ABB 1SVR730740R0300 Industrial Safety Relay Module

ABB 1SVR730740R0300 is the CM-TCS.13S temperature-monitoring relay that safeguards electrical equipment by monitoring temperature with a single sensor circuit and short-circuit detection, offering overtemperature, undertemperature, or combined monitoring. It provides configurable outputs: 2 × 1 c/o or 1 × 2 c/o contacts (DPDT when configured for 2 × 1 c/o), enabling flexible wiring for alarms or interlocks. The unit is powered from 24–240 V AC/DC and senses temperatures from 0 to +200 °C. It uses screw terminals for connections and measures 22.5 mm in width, 85.6 mm in height, and 103.7 mm in depth, with a net weight of 0.151 kg. Ambient operating temperature is −40 to +60 °C (−40 to +85 °C storage). It is RoHS compliant and supports a maximum output circuit voltage of 300 V AC with UL/CSA rating of B300. Terminal conductor capacities include flexible 18–14 AWG (two wires) and flexible 18–16 AWG, or rigid 20–12 AWG (two wires 20–14 AWG). Tightening torque is 7.08 in-lb. The catalog number is 1SVR730740R0300, and the EAN is 4016779852739. Typical applications include temperature monitoring in control panels, safety interlock circuits, and machinery protection where precise 0–200 °C supervision is required.
