8-Channel Relay Outputs – High Load Compatibility:Features dry-contact relay outputs that can switch both AC and DC loads, ideal for driving contactors, lamps, solenoids, and small motors.
High Drive Capacity – Up to 2A per Point:Each output can handle up to 2A current, enabling direct control of medium-power industrial loads without additional relays.
Galvanic Isolation – Strong Noise Immunity:Optically isolated between controller and field side, preventing electrical noise from affecting the CPU and improving system reliability.
Plug-and-Play Installation – Easy Integration:Connects directly to S7-200 SMART CPU via backplane bus; no additional wiring or communication setup required.
Per-Channel LED Indicators – Real-Time Status Feedback:Each output has a green LED to indicate on/off status, facilitating commissioning, monitoring, and troubleshooting.
Supports High-Speed Output (on Selected Channels):Certain outputs can be configured as high-speed PTO or PWM signals, suitable for basic motion control (e.g., stepper motor control).
