Compatible I/O Modules

Main Functions

1. Field Wiring Connection Carrier
    
   Centralize all sensor, actuator, valve, relay field wires onto unified screw terminals, orderly wiring layout for cabinet maintenance.
2. Detachable Split Wiring Design
    
   The terminal base can be unplugged from the I/O module independently. When replacing faulty I/O modules, no need to disconnect field cables, greatly shortening downtime.
3. Vibration-resistant Screw Clamping
    
   Screw fastening eliminates loose wire risks caused by equipment vibration, far more stable than spring terminals for heavy machinery, metallurgy and mining environments.
4. Standardized Signal Routing
    
   Correspond 18 wiring terminals one-to-one with I/O module internal channels, standard pin definition consistent across all matched 5069 I/O modules.
5. Overcurrent & Insulation Protection
    
   Flame-retardant plastic housing prevents fire spread from short-circuit faults; reinforced insulation isolates field signals from PLC backplane power circuits.
6. Quick On-site Troubleshooting
    
   Detachable terminal base allows offline continuity testing of field sensors and actuators without powering off the PLC rack.

Key Advantages

• Screw terminal structure offers superior anti-vibration performance, ideal for stamping, metal processing, heavy conveyor equipment
