Output and Relay Checks
Features:
- Two configurable dynamic measurement channels plus one tachometer input.
- Two isolated 4-20 mA outputs and one onboard double-pole relay.
- DeviceNet networking with local RS-232 configuration through the XM-940 terminal base.
1440-VAD02-01RA is the exact XM-123 aeroderivative execution and is not interchangeable by appearance with another XM dynamic module. The terminal base, transducer type, channel configuration, firmware, DeviceNet node and protection logic must match the controlled installation.
Before removal, record the complete label and series, 1440-TB-A wiring, channel transducers, tachometer source, filters, alarm setpoints, relay logic, 4-20 mA scaling, DeviceNet address and current configuration backup. After installation, validate every measurement and protection path.
The 1440-VAD02-01RA Allen-Bradley XM-123 aeroderivative vibration monitoring module is listed as Obsolete / Discontinued by OEM. Current revision, availability and supplied scope are confirmed in the written quotation.

Important Notice: Confirm the complete order identity, hardware execution, receiving-system configuration and required document revision before replacement.
XM-123 provides two dynamic measurement channels, one tachometer input, two isolated 4–20 mA outputs and one double-pole relay.
The module uses the 1440-TB-A XM-940 terminal base and the documented DeviceNet node settings. Preserve the approved firmware and configuration.
Check sensor bias or power, speed input, analog-output scaling, relay action and every affected alarm or shutdown path.
