Allen-Bradley 1440-TB-C Terminal Base Unit for XM-440

Description:

The Allen-Bradley 1440-TB-C Terminal Base Unit is designed specifically for the XM-440 Master Relay Module (catalog number 1440-RMA00-04RC). It provides all necessary field wiring terminations, including 24V DC power input, four DPDT relay outputs (Normally Open, Normally Closed, and Common contacts), remote relay reset switch input, DeviceNet communication ports (CAN_H, CAN_L, DNet V+, DNet V–, shield), and a serial port (TxD, RxD, RTN) for local configuration. The base unit mounts on a standard 35 mm DIN rail or directly onto a panel/wall. It features a side connector that allows interconnection with adjacent XM modules, simplifying external wiring by sharing power and communication signals. The 1440-TB-C is conformally coated and certified for use in Class I Division 2 hazardous locations and ATEX Zone 2 environments.

Key capabilities

• • Designed exclusively for the XM-440 Master Relay Module

  • DIN rail (35 × 7.5 mm) or panel/wall mounting options

  • Side connector for daisy-chaining power (24V DC, up to 3 A) and DeviceNet signals (300 mA max) to adjacent XM modules

  • Terminal block assignments include:

    • 24V DC power input (terminals 0, 1)

    • Reset relay switch input (terminal 2)

    • Four DPDT relays (Relays 1–4) with N.O., N.C., and common contacts

    • DeviceNet connections (CAN_H, CAN_L, DNet V+, DNet V–, shield)

    • Serial port (TxD, RxD, RTN)

    • Chassis ground terminals

  • Operating temperature range: –20…+65 °C (–4…+149 °F)

  • Storage temperature: –40…+85 °C (–40…+185 °F)

  • Humidity: 5…95% noncondensing

  • Conformally coated circuit boards (IPC-A-610C)

  • UL, c-UL, ATEX, IECEx, CE, RCM, KC, CCC certifications for hazardous locations

  • Terminal screw torque: 0.8 N·m (7 lb·in)

  Applications

  • Mounting and wiring the XM-440 Master Relay Module in machine condition monitoring systems

  • Providing relay outputs for machine protection (shutdown, alarm) in turbines, compressors, generators, pumps, fans

  • Voting logic applications (e.g., 2-out-of-3 overspeed detection systems)

  • Remote reset of latched relays via wired switch or DeviceNet command

  • Integration into DeviceNet networks via the terminal base’s communication ports

  • Use in hazardous locations (Class I Division 2, ATEX Zone 2) with proper enclosure
