Allen-Bradley 1440-TB-B Terminal Base Unit for XM-220

Description:

The Allen-Bradley 1440-TB-B Terminal Base Unit is designed specifically for the XM-220 Dual Speed Module (catalog number 1440-SPD02-01RB). It provides all necessary field wiring terminations, including power supply connections, relay outputs, tachometer inputs, DeviceNet communication, and buffered outputs. 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 and sharing power and communication signals. The 1440-TB-B is conformally coated and certified for use in Class I Division 2 hazardous locations and ATEX Zone 2 environments.

Key capabilities
