2042-3024 WAGO Industrial Automation Components

Wago 2042-3024 is a replacement plug-in relay designed for railway applications with an electromechanical design featuring a green LED. It operates with a rated current of 5A continuously and can handle up to 15A AC inrush maximum current for 4 seconds. The relay is specified with 4NO / 4PST-NO contacts, suitable for operations within an ambient air temperature range of -40°C to +70°C for operation and -40°C to +85°C for storage. It requires a control voltage of 16.8-30Vdc (24Vdc nominal) and has a rated impulse voltage (Uimp) of 0.7...1.25 x Uc. The relay's dimensions are H77.7mm x W25.9mm x D52mm, and it features silver-nickel (AgNi) contacts for the switching mechanism. The rated insulation voltage (Ui) is 4 kV, with a maximum switching voltage of 250Vac and a control voltage for AC at 4-poles (4P). It has a power consumption characteristic of a plug-in design, with Normally Closed (NC) auxiliary contacts. The relay's operation speed is marked by contacts closing in 8ms and opening in 6ms, designed for a frequency of 250 V and capable of 100,000 operations for Normally Closed (NC) circuits and 10,000,000 operations overall.
