WAGO 788-312 Relay Module 24VDC 8A 2CO Grey for DIN Rail

The WAGO 788-312 is a pluggable relay module from the 788 Series, designed for DIN-35 rail mounting in control and interface applications. It accepts a 24 VDC nominal input (±10%) and switches up to 8 A limiting continuous current through 2 changeover contacts, with a maximum switching voltage of 250 VAC. A red LED provides at-a-glance coil status indication on the module face.

Features and benefits:

• Push-in CAGE CLAMP terminals accept solid and fine-stranded conductors from 0.34 to 2.5 mm² without tools, cutting wiring time on dense panels.
• Reinforced insulation between coil and contacts; 5 kVrms dielectric strength between control and load circuit suits demanding installation environments.
• Compact 15 mm module width enables high-density DIN-rail layouts; a separator plate (e.g. 209-191) extends use to voltages above 250 V between adjacent modules.
• Certified to EN 61010-2-201, EN 61810-1, EN 61373, and UL 508; UL listed under file E175199 and EAC approved.
• Wide operating temperature range of -40 to +70°C supports use in harsh ambient conditions and outdoor enclosures.

Applications:

• Switching resistive or inductive loads in PLC output circuits up to 250 VAC / 8 A continuous current.
• Signal isolation between 24 VDC control circuits and AC load circuits in machine control panels.
• Interfacing control signals to AC lighting or heating loads where AC-15 rating (3 A / 250 VAC) is required.
• Rail-mounted relay switching in automation panels where IP20 protection and compact form factor are specified.
