Review ALLEN BRADLEY Ser Reversing Contactor 24vdc 23a 600vac Se #187657

The **Allen-Bradley 104-C23DJ22** is a high-performance, industrial-grade reversing contactor designed for precise control of three-phase AC motors in demanding automation applications. Part of Rockwell Automation s robust **104 Series**, this contactor is engineered to deliver reliable, high-current switching with a compact yet durable construction, making it ideal for integration into PLC-based systems, motor starters, and other industrial control panels. Operating on a **24V DC coil voltage**, it provides a maximum **23 amps of continuous current** at **600V AC**, ensuring efficient handling of standard three-phase motors while maintaining exceptional longevity under frequent switching cycles. The **reversing configuration** allows for seamless forward and reverse motor rotation control, a critical feature in applications such as conveyors, pumps, and material handling systems where bidirectional motion is essential. Constructed with **SE (Standard Environment) ratings**, this contactor is built to withstand typical industrial environments, offering protection against dust, moisture, and temperature fluctuations within specified limits. Its **187657** product designation aligns with Rockwell Automation s extensive documentation and support network, ensuring compatibility with compatible PLCs, relays, and other control components. The contactor s **mechanical interlocking** prevents simultaneous engagement of forward and reverse contacts, safeguarding both the motor and connected equipment from potential damage. With a **low-profile design**, it optimizes space utilization in control panels while maintaining high electrical performance, and its **quick-disconnect terminals** simplify installation and maintenance. Whether deployed in manufacturing, process control, or automation systems, the **104-C23DJ22** delivers dependable operation, minimal arc flash risk, and seamless integration with Rockwell s ecosystem of industrial automation solutions.

### **Pros and Cons of buying a Allen-Bradley 104-C23DJ22 Reversing Contactor (24VDC, 23A, 600VAC, SE, Part #187657)**

1. **Reliable Brand and Quality** Allen-Bradley (now part of Rockwell Automation) is a well-established manufacturer known for durable, high-performance electrical components. This contactor is designed for industrial applications, ensuring long-term reliability in demanding environments.

2. **Reversing Functionality** The unit is specifically a reversing contactor, meaning it can control motor direction by switching between forward and reverse operation. This eliminates the need for additional relays or complex wiring for motor reversal.

3. **24VDC Coil Compatibility** The 24VDC coil makes it suitable for systems using low-voltage control logic, such as PLCs, relays, or solid-state controllers. This is common in modern automation setups.

4. **High Current Rating (23A)** With a 23A rating at 600VAC, it can handle moderate to heavy-duty motor loads (e.g., small pumps, conveyors, or fans). This capacity ensures it won t overheat under typical operating conditions.

5. **Self-Energizing (SE) Design** The "SE" designation indicates a self-energizing (or self-holding) mechanism, which means once energized, the coil remains powered even if the control signal is briefly interrupted (within limits). This prevents momentary power drops from causing unintended motor stops.

6. **Compact and Industrial-Grade Build** The 104 series is known for its robust construction, suitable for panel mounting in industrial environments. It is designed to withstand vibration, dust, and temperature fluctuations.

7. **Easy Integration with PLCs** Compatible with Rockwell Automation PLCs (e.g., ControlLogix, CompactLogix, Micro800), making it straightforward to integrate into automated control systems.

8. **Standardized Part Number** Being a widely available Allen-Bradley part, it is easy to find replacements, documentation, and technical support if needed.

9. **No Auxiliary Contacts Included** While this may seem like a drawback, it also means fewer potential failure points (no extra contacts to wear out). If auxiliary contacts are needed, they can be added separately.

10. **Cost-Effective for Mid-Range Applications** For applications requiring reversing control without extreme environmental harshness, this contactor offers a balance of performance and price.

---

1. **No Auxiliary Contacts** Unlike some reversing contactors that include auxiliary contacts for status indication or interlocking, this model requires separate auxiliary relays if additional switching is needed. This adds complexity and cost.

2. **Limited Environmental Ratings** While industrial-grade, it may not be rated for extreme conditions (e.g., high humidity, corrosive environments, or explosive atmospheres) without additional protection (e.g., enclosure or sealing). For such applications, a more rugged or NEMA-rated model may be needed.

3. **23A Current Limit** While sufficient for many applications, larger motors (e.g., 5 HP or above) may require a higher-rated contactor (e.g., 30A or 40A). Oversizing slightly is safer, but this unit may not be ideal for very high-load applications.

4. **24VDC Coil Dependency** If your system uses a different control voltage (e.g., 120VAC, 110VDC, or 220VDC), you ll need a compatible driver or transformer, adding to system complexity.

5. **No Built-In Overload Protection** Contactors like this do not include overload protection (that s the role of thermal overload relays). You ll need to pair it with a separate overload relay for motor protection.

6. **Potential for Wear Over Time** Like all mechanical contactors, the main and auxiliary contacts (if added) will eventually wear out, requiring replacement. However, with proper maintenance, this unit should last many years.

7. **No Built-In Arc Suppression** While 600VAC is relatively low for industrial contactors, frequent switching of inductive loads (e.g., motors) can generate arcs. Additional snubber circuits may be needed to extend contact life.

8. **Limited Global Availability** Allen-Bradley parts may be harder to source outside North America or in regions with limited distributors. Always verify availability before purchase.

9. **No Built-In Diagnostics** Unlike some modern solid-state relays or smart contactors, this mechanical unit lacks built-in diagnostics (e.g., contact wear indicators or fault reporting).

10. **Replacement Costs** While the initial cost is reasonable, replacing worn contacts or the entire unit over time may add up, especially in high-use applications.

The **Allen-Bradley 104-C23DJ22** is a solid choice for applications requiring **reversing motor control with a 24VDC coil, 23A capacity, and 600VAC rating** in a standard industrial setting. It strikes a balance between performance, reliability, and cost for mid-range applications where environmental conditions are not extreme. Its self-energizing design and compatibility with Rockwell Automation systems make it a practical option for PLC-based controls.

- **Higher current ratings** (e.g., >23A),

- **Auxiliary contacts** for status signaling,

- **Extreme environmental protection** (e.g., NEMA 4X, IP65),

- **Overload protection** (requires separate relay),

- **Arc suppression** for frequent motor switching,

- **Global availability** (check local distributors),

or

- **Diagnostic features** (e.g., contact wear monitoring),

- A higher-rated reversing contactor (e.g., 104-C30DJ22 for 30A).

- A solid-state reversing relay for lower current or high-frequency applications.

- A contactor with built-in auxiliary contacts (e.g., 104-C23DJ22 with optional auxiliary modules).

- A NEMA-rated or explosion-proof enclosure for harsh environments.

---

- You need a **reliable, mid-range reversing contactor** for a **24VDC control system**.

- Your motor load is ** 23A at 600VAC** (e.g., small pumps, conveyors, or fans).

- Your environment is **standard industrial** (not extremely harsh or explosive).

- You are using **Rockwell Automation PLCs** or compatible control logic.

- You are willing to **add auxiliary relays or overload protection separately**.

- You require **higher current** (>23A) or **auxiliary contacts**.

- Your application demands **extreme environmental protection** (e.g., NEMA 4X, IP67).

- You need **diagnostic features** or **smart control** (e.g., contact wear monitoring).

- Local sourcing is a concern (verify availability with a distributor).

**Final Verdict:** For most **standard industrial reversing motor applications within its specs**, this contactor is a **cost-effective, reliable, and well-supported choice**. Always pair it with appropriate overload protection and consider adding auxiliary contacts if needed.
