Core Functions

1. FieldMonitor rack power feed: Delivers stable regulated 24 VDC logic and transducer bias power for all FieldMonitor I/O modules on the baseplate.
2. Built‑in fault protection: Protects against input over‑voltage, reverse polarity and downstream short‑circuit faults to avoid collateral damage to monitoring modules.
3. System health indication: Front‑panel OK LED provides quick visual diagnostic for power‑supply operational status.
4. Backplane power distribution: Distributes power via baseplate internal bus to each plugged‑in signal‑monitor module.
5. Transducer bias power source: Provides required DC bias voltage for proximity probe transducer channels within FieldMonitor system.

Installation, Replacement & Critical Warnings

1. De‑energize 18‑36 VDC primary input power before removing module; non‑hot‑swappable.
2. Only use with compatible 1701/05 or 1701/06 FieldMonitor baseplates; wrong baseplate prevents power‑supply seating and operation.
3. Verify input DC voltage stays within 18‑36 VDC range; excessive input voltage will destroy internal power‑circuit components.
4. After installation, confirm OK LED illuminates; measure 24 VDC backplane output voltage and verify all monitoring modules power‑up normally.

5. Common failure mode: Input‑side electrical surge damage, internal fuse blow. Investigate cabinet DC‑bus transients when entire FieldMonitor rack loses power.
