8-Channel Relay Output – AC/DC Load Compatible:Each of the 8 outputs is a dry-contact relay, capable of switching both AC and DC loads (e.g., 220V contactors, 24V solenoids, indicator lamps), offering high application flexibility.
High Load Capacity – Strong Driving Capability:Each contact can handle up to 2A at 230V AC or 30V DC, allowing direct control of small to medium-sized actuators without additional interface relays.
Strong Galvanic Isolation – Enhanced Safety:Provides 500V AC isolation between field outputs and backplane bus, preventing high-voltage transients from damaging the PLC and ensuring operator safety.
LED Indicators for Real-Time Output Status:Each output has a green LED that lights up when the PLC output is active, enabling visual confirmation during commissioning, operation, and troubleshooting.
Supports Various Load Types – Highly Versatile:Suitable for both resistive loads (e.g., lamps, heaters) and inductive loads (e.g., contactors, solenoids), making it ideal for diverse industrial applications.
