Technical Specifications Back‑plane bus powered; Multi‑channel digital input filter circuits; Galvanic signal isolation Operating temperature:0℃~+60℃; Storage temperature:‑40℃~+85℃; Humidity:5‑95% non‑condensing Mounting:rack plug‑in mounting
Functional Features Filters surge and contact bounce interference for field digital inputs. Galvanic signal isolation. Hardware self‑diagnosis. Front‑panel LED channel status indication.
Application Scenarios Digital input signal conditioning for GE control rack. Heavy‑industry switch‑status signal acquisition. Spare replacement filter board for cabinet maintenance.
Performance Parameters Effective suppression of field surge and bounce noise. Stable digital‑signal transmission performance. Reliable hardware fault detection.
Material Composition Flame‑retardant plastic housing. Multilayer conformal coated PCB. Filter‑isolation components, back‑plane plug‑in connector and field signal terminals.
Structural Characteristics Standard rack plug‑in module. Rear back‑plane bus connector. Front‑panel field wiring terminals and LED indicators. Metal locking screw.
Working Principle Field digital input signals enter front terminals and pass multi‑stage filter‑isolation circuits. Processed digital status data transmits to controller CPU via rack back‑plane bus.
Installation Requirements Cut rack power before installation. Insert board into target rack slot and tighten locking screw. Connect field digital signal cables. Restore rack power, verify input status matches field actual conditions.
Usage Notes Hot‑plug under power is prohibited. Cable shielding grounding shall comply with site specifications. Observe anti‑static handling rules.
