859-702 WAGO Signal Relays

Wago 859-702 is a solid-state relay (SSR) designed for fixed-type applications. It features CAGE-CLAMP spring connections for secure and reliable connectivity. This SSR operates with a rated current of 0.5A continuously and supports a rated voltage range of 20Vdc to 30Vdc, with a nominal voltage of 24Vdc. The design incorporates a red LED, a 3-wire connection, and low-side switching. Although it does not specify a supply voltage in AC, it operates within an ambient air temperature range for operation from -25°C to +55°C and has a storage temperature range from -40°C to +70°C. The control voltage DC is specified with a net height of 4-6.25Vdc, nominally 5Vdc, and it is designed for single-pole / single-phase / 1-pole (1P) applications. The unit's dimensions are H91mm x W6mm x D56mm, with a 6mm width, making it suitable for DIN-35 rail mounting. It features a rapid response time for switching on and off, measured in microseconds (7μs for switching on and 15μs for switching off), and supports a 10kHz switching frequency. The SSR can operate within a humidity range of 5-95% relative humidity (RH), with no condensation permissible.
