WAGO 788-512 Relay Module 24VAC 8A 2CO Grey for DIN Rail

The WAGO 788-512 is a relay module for DIN-35 rail mounting that accepts a 24 VAC nominal input voltage and switches two changeover contacts at up to 8 A limiting continuous current. At 15 mm wide, it integrates into compact control cabinet assemblies with reinforced insulation between coil and contacts and a red LED for at-a-glance status monitoring.
