3RS2500-2AA30 TEMPERATURE MONITORING RELAY

Temperature monitoring relay Pt100, thermocouple J, K 1 threshold value, width 22.5 mm Overshoot and undershoot 24 V AC/DC 1 change-over contact, quiescent current principle Spring-type terminal (push-in) Temperature monitoring relay SIRIUS 3RS2 for the measurement of temperatures in solid, liquid and gaseous media, e.g. for open and closed loop control of processes or for protecting motors and plants against excessive temperatures. The devices are easy to operate using rotary and slide switches, the hysteresis is adjustable. The relays are suitable for type Pt100 and Pt1000 sensors as well as type J and type K thermocouples. The family of 3RS temperature monitoring relays consists of analog and digital adjustable relays for the connection of between one and three sensors (resistance sensors or thermocouples). They are available with screw-type or spring-type terminals. Likewise, versions are available with communication via IO-Link. Labels, push-in lugs and sealable covers are available as accessories. SIRIUS relays – one range for every application.
