193-ECPM2 Allen‑Bradley Panel Mounting Base

Product Specifications (Parameters)

The 193-ECPM2 acts as an interface between the controller and the current transformers (CTs).

Key Product Features & Advantages

• Modular Flexibility: Allows the E3 relay to be used with external Current Transformers (CTs), enabling the protection of very large motors that exceed the standard integrated current range of the relay.

• Enhanced Precision: Provides accurate monitoring of motor current, allowing for sophisticated thermal modeling and fault detection.

• Reduced Footprint: By separating the sensing module from the main logic, it allows for more flexible cabinet wiring and space management.

• Comprehensive Protection: Supports trip functions for:

• Thermal Overload

• Phase Loss / Phase Unbalance

• Ground Fault (depending on configuration)

• Stall/Jam Protection

Product Applications

The 193-ECPM2 is primarily used in heavy industrial environments where motor uptime is critical.

1. Large Motor Control Centers (MCCs): Used in water treatment, mining, and oil & gas where high-horsepower motors are common.

2. Pumping Stations: Monitoring for dry-run or jam conditions in large-scale fluid transport.

3. Conveyor Systems: Protecting against mechanical jams in manufacturing and logistics.

4. Compressors & Fans: Ensuring thermal protection for HVAC and industrial air handling units.

Important Usage Notes (Precautions)

• Wiring Integrity: Ensure the ribbon cable connecting the 193-ECPM2 to the E3 base is securely seated and protected from electromagnetic interference (EMI).

• CT Scaling: You must correctly configure the CT ratio in the E3 relay software (such as RSLogix/Studio 5000) to ensure the current readings are accurate. Incorrect scaling will lead to nuisance trips or failure to protect the motor.

• Environment: While robust, the module should be installed in an enclosure that meets the necessary NEMA/IP rating for the specific environment (e.g., protecting against conductive dust or moisture).

• Firmware Compatibility: Ensure the firmware of your E3/E3+ base module is compatible with the ECPM2 expansion module.
