Working Principle CPU delivers output commands through backplane bus. Opto‑coupler drives sourcing transistor to output positive 24VDC signal to field load side. Galvanic isolation separates field circuit and PLC logic circuit. Overload detection circuit monitors channel condition and sends status information back to CPU.
Installation Requirements Mount module into Series 90‑30 rack slot. Follow official grounding specification. Pay attention to wiring polarity of sourcing output loads. Separate field wiring from high‑voltage power cables. Verify load working voltage matches 24VDC. Power‑off rack for module replacement, hot‑swap unavailable. Keep ambient condition within specification limits.
Usage Notes Per‑channel output current must not exceed 0.5A rating. Do not connect load voltage higher than 24VDC. Install free‑wheeling diode for inductive loads. Keep terminals clean from dust. Check group LED indicators periodically. On‑site disassembly of module is forbidden. Stay away from corrosive gas, liquid splash and oil mist.
