- Housing: Flame-retardant ABS
Working Principle: When a 24V DC signal is applied to an input terminal, current flows through the input LED of an optocoupler. The optocoupler’s phototransistor switches on the logic side, sending a “1” to the CPU. When the signal is removed, the optocoupler turns off, sending a “0”. The shared common return per group of 8 allows wiring flexibility — all 8 inputs in a group can share one negative wire. Installation Requirements:
- Wire all field devices to the module’s terminal block
- Connect the common return (COM) for each group of 8 to the negative side of the 24V DC supply
- Use shielded cable for long runs; ground shield at PLC end
- Do not mix AC and DC inputs on the same module
Usage Notes:
- This is a SINK (NPN) module — your field devices must be NPN/PNP-sinking type
- If you have PNP (sourcing) sensors, use IC200MDL240 (sourcing version) instead
- The 1.6ms filter eliminates contact bounce but adds slight delay — disable for high-speed counting applications
- Maximum cable length: 100m for 24V DC inputs with 3mA current
