Allen-Bradley 1440-TB-A Terminal Base Unit for XM-124

Description:

The Allen-Bradley 1440-TB-A Terminal Base Unit is designed specifically for the XM-124 Standard Dynamic Measurement Module (catalog number 1440-SDM02-01RA). It provides all necessary field wiring terminations, including 24V DC power input, two dynamic transducer inputs with buffered outputs, one tachometer input with buffer, two isolated 4…20 mA outputs, one onboard relay (SPST, Form A) contacts, DeviceNet communication ports (CAN_H, CAN_L, DNet V+, DNet V–, shield), a serial port (TxD, RxD, RTN) for local configuration, and switch inputs for setpoint multiplication and remote relay reset. 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 (24V DC, up to 3 A) and DeviceNet signals (300 mA max). The 1440-TB-A is conformally coated and certified for use in Class I Division 2 hazardous locations and ATEX Zone 2 environments.
