8-Channel Relay Outputs with High Load Capacity:Features 8 relay outputs, each capable of switching up to 2A at 250V AC or 30V DC, ideal for directly driving contactors, solenoid valves, lamps, and small motors without additional relays.
Galvanic Isolation for Enhanced Safety:Provides opto-isolation between output channels and backplane bus, protecting the CPU from electrical noise and field-side disturbances.
AC/DC Load Compatibility for Flexibility:Supports both AC and DC loads, making it versatile for a wide range of industrial control applications.
Status Feedback Capability (Indirect Diagnosis):Relay operation status can be indirectly monitored via system diagnostics, helping verify command execution.
LED Indicators for Real-Time Monitoring:Each output channel has a green LED to show active status, enabling fast visual troubleshooting and commissioning.
