Siemens Temperature monitoring relay

Siemens digital industrial temperature monitoring relay 3RS2500-2AA30. Manufacturer: Siemens. Designation: Temperature monitoring relay PT100, thermocouple type: 3RS2500-2AA30. Electrical connection type: spring-loaded terminal. Rated control supply voltage Us at AC 50 Hz: 24 V. Rated control supply voltage Us at AC 60 Hz: 24 V. Rated control supply voltage Us at DC: 24 V. Voltage type for operation: AC/DC. Number of measuring circuits: 1. Fault storage possible: no. External reset possible: no. Number of contacts as changeover: 1. Width: 22.5 mm. Height: 100 mm. Depth: 90 mm.

The temperature monitoring relay PT100, thermocouple types J and K, has 1 threshold, a width of 22.5 mm, and monitors over- and under-limit conditions at AC/DC 24 V with 1 changeover contact in a quiescent current principle. It is suitable for measuring temperatures in solid, liquid, and gaseous media, for example, to control and regulate processes or to protect motors and systems from excessive temperatures. The devices are easy to operate via rotary and toggle switches, and the hysteresis is adjustable.

The relays are compatible with sensor types PT100, PT1000, thermocouples type J and type K. The family of temperature monitoring relays 3RS consists of analog and digitally adjustable relays for connecting one to three sensors (resistance sensors or thermocouples). They are available with removable screw or spring-loaded terminals. Variants with communication via IO-Link are also available. Accessories include designation labels, insertion tabs, and sealable cover caps. SIRIUS relays - a program for all cases.
