789-324 WAGO Industrial Automation Components

Wago 789-324 is a fixed-type relay module featuring CAGE-CLAMP spring connections for secure and maintenance-free wiring. It is designed with a MANUAL / OFF / AUTO switch, a red LED indicator, and an electromechanical design. This relay supports a rated current of 16A for continuous operation and can handle up to 165A AC inrush maximum current for 20ms. It is equipped with 1NO / SPST-NO (Single Pole Single Throw - Normally Open) contacts, suitable for applications requiring a single-pole configuration. The supply voltage for AC operations is specified as -25°C to +40°C, with an ambient air temperature for storage ranging from -40°C to +70°C. The control voltage (DC) is within 21.6-28.8Vdc (24Vdc nominal), and the relay operates at a rated insulation voltage (Ui) of 4 kV. It features a control voltage for AC as single-pole / 1-pole (1P) and is designed for mounting on a DIN-35 rail. The dimensions are H90mm x W17.5mm x D55mm, with a width of 17.5mm. The contacts are made of Silver-Tin (AgSnO) to handle short circuit breaking efficiently. The rated operating voltage (Ue) is 250Vac max. (switching voltage), with a rated impulse voltage (Uimp) of 0.9...1.2 x Uc. It has a power consumption suitable for DIN-35 rail installations and supports up to 5 000 000 operations, demonstrating its durability. The relay operates effectively within 75% relative humidity (RH), with no condensation permissible, ensuring stable performance in various environmental conditions.
