Technical Specifications Multi‑channel isolated digital input and relay drive output. Auxiliary power supplied by system rack, typical power consumption 6.7 W. Operating temperature ‑10 ℃ to +55 ℃, storage temperature ‑40 ℃ to +85 ℃, non‑condensing relative humidity 5%‑95%. Conformal coated surface, channel isolation voltage 2000 V AC.
Functional Features Receives and isolates multi‑path external device status signals. Outputs multi‑group relay control commands for field equipment. On‑board LED gives visual indication for each channel working condition. Built‑in hardware self‑diagnosis function. Conformal coating enhances environmental adaptability for industrial cabinet.
Application Scenarios Spare‑part component for generator excitation system and high‑power industrial drive equipment. Suitable for power plant and heavy‑industry site maintenance and spare‑part replacement.
Performance Parameters Stable signal transmission for each independent channel. Isolation circuit restrains electromagnetic interference introduced from field side. LED indicators provide intuitive fault prompt for channel abnormality.
Material Composition Multilayer glass‑fiber epoxy printed circuit board. Signal conditioning chips, optocoupler isolation assemblies and relay drive units. Conformal protective coating. Multi‑pin back‑plane plug‑in connectors. Screw‑type signal terminals.
Structural Characteristics Plug‑in circuit board matching cabinet internal slot. Board edge fitted with back‑plane connector and multi‑channel signal terminals. Mechanical fixing holes for fastening. Weight approximately 0.66 kilogram.
Working Principle Control instructions from main control unit pass through back‑plane connector to this board. After isolation and drive processing, relay contacts output control signals to external secondary‑loop circuits.
Installation Requirements Fully cut off rack auxiliary power before installation. Insert UFC760BE1042 into corresponding slot and tighten fixing screws. Ensure connectors are fully locked. Restore power supply, observe on‑board LED status and execute whole‑equipment function test.
Usage Notes Implement anti‑static protection during handling. Avoid damage to conformal coating layer. Forbid hot‑plug operation under powered status.
