Siemens announces Sirius 3RP25 time relays

October 24, 2014 - Siemens announces Sirius 3RP25 time relays. This series ranges from monofunctional devices with common functions such as switch-on and return delay, right up to multifunctional devices for every application. The latter integrate up to 27 functions in a single device.

The monofunctional devices with a width of 17.5mm are especially space-saving in the control cabinet. The wide voltage range for direct current and alternating current (AC/DC) has been expanded uniformly to 12V to 240V, enabling the number of device variants to be almost halved. This minimizes logistics and simplifies configuring and service. The Sirius 3RP25 time relays are equipped with the necessary international certification and can therefore be used globally.

The devices are also equipped with a watchdog function. This is especially suitable for controlling clock times in cyclic sequences, thus providing benefits in many industrial applications, such as conveyor belts. The variants with wear-free semiconductor output are used especially in applications with frequent, short switching operations, such as longitudinal feed in punching or embossing machines. The devices are even more flexible in use than the predecessor generation, in applications involving compressors or elevators, for example, or in woodworking.

Siemens offers the product range with removable terminals in widths of 17.5mm or 22.5mm. In the mid-term, the new devices will replace time relays of the 3RP15 range.
