2042-3074 WAGO Signal Relays

Wago 2042-3074 is a replacement plug-in relay designed for railway applications with an electromechanical design. It features a green LED indicator and operates with a rated current of 5A continuously and can handle up to 15A AC inrush maximum current for 4 seconds. The relay is equipped with 3NO / 3PST-NO contacts and 1NC / SPST-NC contacts, supporting a supply voltage of -40°C and an ambient air temperature for operation ranging from -40°C to +70°C. For storage, the temperature tolerance extends from -40°C to +85°C. The control voltage range is specified as 16.8-30Vdc (24Vdc nominal), with a rated impulse voltage of 0.7...1.25 x Uc and a net width of 250Vac max for switching voltage. The rated insulation voltage stands at 4 kV, and the device features a 4-pole design with a power consumption characteristic of plug-in type and Normally Closed (NC) auxiliary contacts. The dimensions are H77.7mm x W25.9mm x D52mm, and the contacts are made of Silver-Nickel (AgNi) for enhanced durability, supporting up to 10 000 000 operations for the diameter and 100 000 operations for the number of Normally Closed (NC) circuits. The relay operates with a control voltage for AC, has an IP20 communication protocol, and offers a short circuit breaking rating with a speed of operation for contacts closing at 8ms and for contacts opening at 6ms.
