Information

Overview Manuals Common Applications Product Precautions

Built for aeroderivative gas-turbine monitoring, the 1440-VAD02-01RA combines configurable vibration acquisition, speed reference and local analog retransmission in one XM module.

Accepts two dynamic-measurement channels from eddy-current probes, accelerometers or compatible voltage-output devices.
Provides one tachometer input covering 1 to 50,000 events per revolution and up to 20 kHz input frequency.
Includes two individually programmable, isolated 4-20 mA outputs with a documented maximum load of 300 ohms.
Communicates over DeviceNet at 125, 250 or 500 kbit/s and provides an RS-232 configuration interface.

The vibration inputs, tachometer reference, isolated retransmission outputs and network configuration form one measurement path; keep their ranges and scaling together during replacement.

Important Notice: Confirm the complete 1440-VAD02-01RA catalog number, firmware, terminal base, transducer type, channel ranges, tachometer setup and DeviceNet configuration before installation.

Aeroderivative vibration monitoring

Conditions two configured vibration channels from the documented sensor families.

Speed-reference capture

Uses the tachometer input for speed-related monitoring and analysis functions.

Analog retransmission

Provides two isolated 4-20 mA outputs for selected measured values.

DeviceNet integration

Exchanges module data and status with a compatible DeviceNet control architecture.

Read the applicable product and site instructions before work. Verify 1440-VAD02-01RA, the installed host and every connected interface before isolation or replacement.

Match the complete 1440-VAD02-01RA catalog number and recorded firmware before work.

Record both transducer types, sensitivities, channel ranges and installed terminal-base wiring.

Capture the tachometer events-per-revolution value and observed speed before isolation.

Back up DeviceNet address, data rate, produced data and alarm or relay configuration.

Isolate sensor, tachometer, output-loop and network conductors using the approved procedure.

Restore shielding, grounding, polarity and 4-20 mA scaling exactly as documented.

Review module, channel, tachometer and network status indicators after energization.

Function-test vibration response, speed tracking and both analog outputs before release.

Technical notes

Verify the complete 1440-VAD02-01RA catalog number, firmware, terminal base, sensor type, channel ranges, tachometer setup, DeviceNet address and 4-20 mA scaling before replacement or commissioning.
