Performance Parameters Input filter time is configurable Fault tolerance: Single channel abnormal signal does not impact other channels Designed for long‑term continuous operation Shock & vibration: Comply with IEC 60068
Structural Characteristics Standard plug‑in module for Series 90‑30 backplane slot Front‑panel separate LED indicator for every input channel Front‑side field wiring terminal block Backplane gold‑finger bus contact Internal opto‑coupler and filter circuit assembly Mechanical locking latch
Working Principle Field 24VDC switch signal enters module via front terminals. Hardware filter eliminates bounce and high‑frequency noise. Opto‑coupler completes galvanic isolation between field side and PLC logic side. Convert isolated signal into logic data and transfer to CPU through backplane bus. Front LED reflects real‑time channel on‑off state.
Installation Requirements Install module into designated rack slot. Execute rack protective grounding as specification. Separate 24VDC signal wiring from high‑voltage power cables. Confirm input voltage within rated range before power‑on. Power off rack for module replacement, hot‑swap not supported. Keep ambient environment without condensation.
Usage Notes Never apply voltage over 30VDC to input terminals. Reduce cabinet dust accumulation. Check LED indicators regularly. Adjust filter parameters via GE programming software. Do not disassemble module on site. Keep away from corrosive gas, liquid splash and oil mist.
