1440-VAD02-01RA XM-123 Aeroderivative Module

1440-VAD02-01RA is the XM-123 two-channel vibration monitor for aeroderivative gas turbines. It measures vibration and tachometer speed, supports tracking or bandpass filtering per channel, and can exchange live status and data over DeviceNet.

1440-VAD02-01RA accepts standard eddy-current probe systems, IEPE accelerometers and voltage-output dynamic measurement devices such as velocity or pressure transducers. The two vibration channels are configured for the chosen transducer signals.

1440-VAD02-01RA uses DeviceNet for real-time data and status exchange with compatible control systems. Local configuration is available through its RS-232 serial port; DeviceNet carries the communication protocol, while module power is supplied independently.

1440-VAD02-01RA provides two independently programmed isolated 4–20 mA outputs and one onboard DPDT relay. An XM-441 Expansion Relay module can add four relays through the compatible terminal base.

1440-VAD02-01RA mounts on the XM-940 Dynamic Measurement Terminal Base, catalog number 1440-TB-A, through a keyswitch and 96-pin connector. Match the base, field wiring and installed sensor arrangement before replacing the module.

1440-VAD02-01RA requires +21.6 to +26.4 V DC module power and is specified for operation from −20 to +65 °C. The official manual lists 300 mA maximum module current; confirm the installed power architecture.

1440-VAD02-01RA should be identified by its complete catalog number, 1440-TB-A terminal-base requirement, sensor types, DeviceNet setup and installed firmware or configuration needs. Include quantity and a clear nameplate photo so the replacement can be checked against the existing system.
