Allen-Bradley 193-EC2CB

Overview

The Allen-Bradley 193-EC2CB E3 Plus electronic motor protection relay stands as a robust and intelligent solution for safeguarding industrial motors. Engineered for motors operating within the 5–25 amp full load current range, this Series B model integrates advanced protection capabilities with seamless communication. It features DeviceNet communication for streamlined integration into existing control systems, internal ground fault detection for enhanced safety, and a PTC thermistor input for precise motor winding temperature monitoring. With its 4 digital inputs and 2 relay outputs, the 193-EC2CB delivers comprehensive protection, real-time diagnostics, and local control functionality, all within a compact and efficient package. Leveraging DeviceLogix, it enables faster control response by executing local logic, minimizing reliance on a central PLC.

This versatile relay is designed for direct mounting to 100-C23 to C30 contactors, simplifying installation and reducing wiring complexity. Its adjustable trip class (Class 5–30) allows for tailored protection to suit various motor applications, while thermal memory ensures continuous heat model maintenance even after power loss. Advanced phase monitoring detects critical conditions like phase loss and imbalance, further extending motor lifespan and preventing costly downtime. The 193-EC2CB is an ideal choice for intelligent protection in low- to mid-range motor applications across diverse industrial environments.
