Working Principle CPU sends output command via backplane bus. Internal opto‑coupler drives sinking transistor to switch on‑off, control DC power loop of field loads. Galvanic isolation separates PLC logic circuit and field DC circuit. Short‑circuit detection circuit monitors channel status and feeds fault information back to CPU.
Installation Requirements Insert module into valid rack slot. Implement rack protective ground. Distinguish positive and negative polarity for field DC wiring. Separate DC output wiring from high‑voltage cables. Confirm load voltage matches 24VDC rating. Power‑off rack before module replacement, hot‑swap forbidden. Maintain qualified ambient temperature and humidity.
Usage Notes Each channel output current cannot exceed 0.5A. Do not connect voltage higher than 24VDC to output terminals. For inductive DC loads, install free‑wheeling diode externally. Avoid dust‑caused poor terminal contact. Check LED indicators regularly. On‑site disassembly is prohibited. Keep away from corrosive gas, liquid splash and oil mist.
