FAQs
Begin by verifying the 19-300 VDC or 40-250 VAC supply is within range, then mount the device with removable terminals for easy wiring. Connect 8 digital inputs and 9 digital outputs to the control system, and wire the two analog inputs/outputs for voltage and current sensing. Configure communications for 61850, M-Bus TCP, or DNP3 TCP/UDP over Ethernet RJ45, and ensure proper network addressing for SCADA integration. Verify protection settings and perform functional testing before commissioning.
The unit provides 8 digital inputs, 9 digital outputs, 2 analog inputs, and 2 analog outputs. It supports a power supply range of 19-300 VDC and 40-250 VAC, with a 50/60 Hz frequency rating.
