The WAGO 789 series fixed-type relay module features a manual/off/auto switch and a red LED indicator. It is a single-pole, normally open (1NO/SPST-NO) electromechanical relay with a control voltage range of 21.6-28.8Vdc (24Vdc nominal). The relay is rated for a continuous current of 16A and utilizes CAGE CLAMP connections for secure wiring. It is designed for DIN-35 rail mounting with a width of 17.5mm and has an IP20 protection rating. The contacts are made of Silver-Tin (AgSnO) material, and it is equivalent to the model 789324.
