2042-3879 WAGO Signal Relays

Wago 2042-3879 is a replacement plug-in relay designed for various automation applications. It features an electromechanical design with a green LED indicator and operates with a rated current of 3A continuous and can handle up to 15A AC inrush maximum current for 4 seconds. The relay is equipped with 3NO/3PST-NO (3 Pole Single Throw - Normally Open) and 1NC/SPST-NC (Single Pole Single Throw - Normally Closed) contact types. It recommends a minimum switching load of 12V / 10mA and operates within an ambient air temperature range for operation of -40°C to +50°C and for storage from -40°C to +85°C. The relay has a degree of protection rated at IP20 and supports a control voltage range of 21.6-253Vdc, including nominal voltages of 24Vdc, 120Vdc, 200Vdc, 220Vdc, and 230Vdc. It features a rated impulse voltage (Uimp) of 0.9...1.1 x Uc and a net width of 250Vac max. for switching voltage. The rated insulation voltage (Ui) is 4 kV, and it is designed with 4 poles (4P). The relay's power consumption matches its impulse voltage rating, and it comes in a plug-in design with dimensions of H77.7mm x W25.9mm x D52mm. The manufacturer specifies the use of Silver-Nickel (AgNi) contacts for durability. The operating and closing times are 8ms and 6ms, respectively, for ON to OFF and OFF to ON transitions. It is designed for a rated operating voltage (Ue) of 250 V and is capable of 100,000 operations phase-to-phase with a power dissipation/losses capacity of 10,000,000 operations.
