Technical Specifications Power supplied by rack back‑plane bus; Multi‑channel signal filter circuits Operating temperature:0℃~+60℃; Storage temperature:‑40℃~+85℃; Humidity:5‑95% non‑condensing Mounting:rack plug‑in mounting
Functional Features Suppresses industrial surge and electromagnetic interference for incoming field signals. Signal conditioning processing. Front‑panel LED for power and fault status. Built‑in hardware self‑diagnosis.
Application Scenarios Signal noise filtering for GE DCS control rack. Heavy‑industry field signal conditioning. Spare replacement module for cabinet maintenance.
Performance Parameters Effective surge and noise suppression. Stable signal transmission performance. Reliable self‑diagnosis capability.
Material Composition Flame‑retardant plastic housing. Multilayer conformal coated PCB. Filter and surge‑suppression components, back‑plane plug‑in connector, field terminals.
Structural Characteristics Standard rack plug‑in mechanical structure. Rear back‑plane bus connector. Front‑panel signal terminals and LED indicators. Metal locking screw for rack‑slot fixation.
Working Principle Field signals enter front terminals and pass multi‑stage filter and surge‑absorption circuits. Processed signals go to controller via rack back‑plane bus. On‑board circuit monitors module health status.
Installation Requirements Cut rack power before installation. Insert module into rack slot and tighten locking screw. Connect field signal cables. Restore power and verify signal quality in engineering software.
Usage Notes Do not hot‑plug under powered condition. Cable shielding grounding shall follow project specifications. Anti‑static handling required.
