Working Principle RX3i CPU sends digital control value via backplane bus. Internal D/A converter translates digital data into analog signal. Drive circuit outputs standard current or voltage signal to field actuators. Diagnosis circuit monitors output load and fault state.
Installation Requirements Insert module into RX3i rack slot. Implement cabinet protective grounding. Use shielded twisted‑pair for analog output wiring. Separate analog signal cables from high‑voltage power cables. Power‑off rack before module replacement, hot‑swap not supported. Operate within rated temperature and humidity range.
Usage Notes Configure output signal type through programming software. Confirm field load impedance matches module output specification. Single‑end ground for cable shield layer. Check LED status periodically. Forbid on‑site disassembly. Keep away from corrosive gas, liquid splash and oil mist.
