Core Functional Features
- 16-channel high-density transistor output, compact size reduces cabinet space occupation
- Built-in freewheeling protection diodes for inductive loads such as small solenoid valves
- Distributed XIOC bus cascading, long-distance remote output control up to 100 m from PLC main station
- Overcurrent short-circuit protection per independent channel, single-channel fault does not affect other output points
- Front panel LED indicators for each channel’s output on/off status
Working Principle
After receiving output control commands from XC PLC via XIOC bus, the module’s drive chip controls the conduction of each channel’s MOSFET transistor to output 24 V DC voltage to field actuators. Each output channel integrates independent current sampling protection circuit; when load current exceeds 0.35 A, the channel is automatically locked off to avoid burnout. The optocoupler isolates PLC internal control circuit from field load circuit to prevent surge voltage generated by inductive loads from damaging the main controller.
Structural & Material Characteristics
- Housing: UL94 V0 flame-retardant plastic, same series unified appearance with XIOC-16DI
- Output drive components: Low on-resistance power MOSFET per channel
- Wiring terminals: Quick spring push-in terminals for fast on-site wiring
Installation Requirements
- DIN rail mounting inside PLC cabinet, can be cascaded with XIOC-16DI in arbitrary order
- Field output cables must be separated from high-current power cables with minimum 20 mm spacing
- Inductive loads must add parallel freewheeling diodes at field terminals for secondary protection
Application Scenarios
Automated production line indicator light control, small conveyor solenoid cylinder drive, packaging machine auxiliary relay control, environmental monitoring equipment alarm light output, logistics sorting equipment actuator control.
Operation & Maintenance Precautions
- Forbid parallel multiple inductive loads on a single channel to avoid exceeding 0.3 A current limit
- Do not directly drive large contactors with coil current exceeding 0.3 A; must add intermediate relays
- Check output channel load current regularly to prevent long-term near-limit load accelerating transistor aging
