Allen Bradley 1440-TB-B Terminal Base

Product Introduction

The Allen Bradley 1440-TB-B Terminal Base is specifically designed for Rockwell Automation 1440 series measurement modules, providing a reliable screw clamp interface and side connector for seamless module interconnection.

It facilitates organized and secure wiring connections, transmitting primary power, DeviceNet protocol power, and expansion signaling to adjacent modules. This design ensures stable operation in industrial environments while maintaining compact and efficient installation layouts.

The terminal base supports XM-220 and XM-320 modules, with a single slot layout that is ideal for tight panel spaces. Terminal screws are rated for 0.8 N·m torque, ensuring secure clamping of wiring while minimizing the risk of loose connections.

Designed for rail mounting, it accepts 24 V DC input from a Class 2 supply and is built to withstand industrial environmental conditions, operating down to –20 °C and tolerating high relative humidity in noncondensing environments.

This terminal base is widely used in process monitoring, measurement systems, distributed I/O applications, and control cabinets requiring reliable module power and signaling.
