8-Channel Relay Output – AC/DC Load Compatible:Each of the 8 outputs is a dry-contact relay (SPDT), capable of switching both 230V AC and 30V DC loads, ideal for driving contactors, solenoids, lamps, and small motors.
High Load Capacity – Direct Drive for Power Devices:Each channel supports up to 2A, enabling direct control of medium-sized actuators (e.g., 220V AC contactors, 24V DC valves), reducing the need for interface relays.
Group-Based Galvanic Isolation – Strong Noise Immunity:Features channel grouping with 500V AC isolation between groups, minimizing ground loops and crosstalk, enhancing system reliability and safety.
LED Indicators for Real-Time Output Status:Each output has a green LED that lights when active, enabling visual confirmation during commissioning, operation, and troubleshooting.
Supports Mixed Load Types – Highly Versatile:Suitable for both resistive (e.g., lamps, heaters) and inductive loads (e.g., contactors, relay coils), making it ideal for diverse industrial applications.
