788-355 WAGO Signal Relays

Wago 788-355 is a plug-in relay assembly featuring push-in CAGE CLAMP spring connections for efficient setup. It is designed with a socket base and ejector, complemented by a red LED indicator and an electromechanical design. This relay supports a rated current of 16A for continuous operation and can handle up to 120A AC inrush maximum current for 20ms. It is equipped with 1NO / SPST-NO (Single Pole Single Throw - Normally Open) contact type and operates within an ambient air temperature range of -40°C to +70°C for both operation and storage. The relay is designed for a supply voltage of 24Vdc nominal, within a range of 20.4-28.8Vdc, and has a rated impulse voltage of 0.85...1.2 x Uc. Its dimensions are H86mm x W15mm x D64mm, with a width of 15mm, suitable for DIN-35 rail mounting. The relay features Silver-Tin (AgSnO) contacts for the short circuit breaking rating and has a rated operating voltage (Ue) of 250Vac max. (switching voltage), with a rated insulation voltage (Ui) of 4 kV. It supports a control voltage (AC) of single-pole / 1-pole (1P) and has a power consumption tailored for DIN-35 rail installation. The relay's performance is characterized by a switching speed of 8ms for contacts closing and 2ms for contacts opening, ensuring durability with up to 30,000,000 operations. It adheres to an IP20 communication protocol for protection.
