859-720 WAGO Signal Relays

Wago 859-720 is a fixed-type solid-state/static relay (SSR) featuring CAGE-CLAMP spring connections for secure and reliable connectivity. It is designed to handle a rated current of 3A continuously and operates with a rated voltage (DC) range of 10Vdc to 30Vdc, with a nominal voltage of 24Vdc. The SSR is equipped with a red LED for status indication, supports a 3-wire connection, and utilizes low-side switching. It does not require a supply voltage (AC), and it is designed to operate within an ambient air temperature range of -25°C to +40°C and can be stored in temperatures ranging from -40°C to +70°C. The control voltage (DC) specification is 16-30Vdc (24Vdc nom.), and it features a single-pole/single-phase/1-pole (1P) design. The SSR's dimensions are specified as H91mm x W6mm x D56mm, with a width of 6mm, making it suitable for mounting on a DIN-35 rail. It offers a response time of 30μs for switching on and 75μs for switching off. The SSR is capable of a 1kHz switching frequency at a 2A load and a 2kHz switching frequency at a 1A load. It operates effectively within a humidity range of 5-95% relative humidity (RH), with no condensation permitted.
