Working Principle RX3i CPU sends output control commands through backplane bus. Opto‑coupler array drives sinking transistor groups to complete on‑off action for external 24VDC loads. Galvanic isolation separates field circuit and PLC internal logic. Protection circuit detects over‑current fault and feeds status back to CPU.
Installation Requirements Insert module into RX3i rack slot. Reliable cabinet protective grounding. Strictly follow DC wiring polarity requirements. 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 range.
Usage Notes Each channel output current cannot exceed 0.5A. Do not apply voltage higher than 24VDC to output terminals. Install external free‑wheeling diode for inductive DC loads. Prevent dust‑caused poor terminal contact. Check group LED indicators periodically. Forbid on‑site disassembly. Avoid corrosive gas, liquid splash and oil mist.
