Working Principle CPU sends output control data via backplane bus. Opto‑coupler array drives sinking transistor groups to switch on‑off status, control external 24VDC field loads. Galvanic isolation isolates high‑noise field circuit and PLC internal logic. Multi‑channel protection circuit detects over‑current fault and feeds status back to CPU.
Installation Requirements Insert module into Series 90‑30 rack slot. Complete reliable protective ground. Strictly follow polarity requirement for field DC wiring. Separate output signal cables from high‑voltage power wiring. Confirm load rated voltage is 24VDC. Power‑off rack before module replacement, hot‑swap not supported. Operate within rated temperature and humidity without condensation.
Usage Notes Each channel output current shall not exceed 0.5A. Prohibit input voltage over 24VDC to output terminals. Equip external free‑wheeling diode for inductive DC loads. Avoid dust deposit on wiring terminals. Check group LED status regularly. Do not disassemble module on‑site. Keep module away from corrosive gas, liquid splash and oil mist.
