Allen-Bradley 193-EC2CB

Overview

The Allen-Bradley 193-EC2CB is a solid-state E3 Plus electronic motor protection relay, designed to protect motors operating in the 5–25 amp full load current range. This Series B model features DeviceNet communication, internal ground fault detection, and PTC thermistor input. With 4 digital inputs and 2 relay outputs, it delivers advanced protection, diagnostics, and local control capability using DeviceLogix.

Key Features

• Full Load Current Range: 5–25A

• Inputs / Outputs: 4 discrete inputs (24V DC), 2 Form C relay outputs

• PTC Thermistor Input: Monitors motor winding temperature

• Internal Ground Fault Sensor: Detects low-level faults (1–5A range)

• Communication: DeviceNet (Series B), slave-only

• DeviceLogix: Local logic execution for faster control response

• Trip Class: Adjustable (Class 5–30)

• Mounting: Directly mounts to 100-C23 to C30 contactors
