Material number:
  • 4 digital outputs
  • Relay module for 250 VDC / 240 VAC
  • 2 normally open contacts and 2 changeover contacts
  • Single-channel isolated outputs

This module is equipped with 4 relay outputs. It can switch DC voltages up to 250 VDC and is therefore suitable for use in power generation systems.
