3. Installation Guide

1. Install the module on standard industrial DIN rail inside DCS control cabinet

2. Connect 24VDC power supply with positive/negative polarity strictly distinguished; redundant power is recommended for critical production lines

3. Connect Ethernet/ControlNet communication cable to upper controller, RS232 port for local parameter debugging

4. Wire analog output terminals to field actuators with shielded cables to reduce signal interference

5. Keep ventilation space ≥20mm around the module; avoid direct sunlight, water splash and corrosive gas contact

4. Operation & Maintenance Notes

1. Do not plug/unplug the module when power is on to prevent circuit burnout

2. Regularly clean aluminum shell dust every 3 months; check cable terminal tightness

3. If communication offline occurs, inspect Ethernet cable and bus address configuration first

4. Replace the module immediately if self-diagnosis light shows red permanent alarm

5. Storage environment must be dry, no condensation; avoid vibration during transportation

5. Safety Warning

• Only certified automation engineers are allowed to install, debug and disassemble this module

• Do not use power supply beyond 22~26VDC to avoid permanent hardware damage

• Not suitable for explosion-proof Zone 0 hazardous areas without matched explosion-proof cabinet

• Disconnect all power before maintenance operation to prevent electric shock risk
