Siemens extends time relay range

Siemens is expanding its portfolio of monitoring and control devices to include a series of new time relays which offer greater space-saving and enhanced functionality.

The Sirius 3RP25 series incorporates everything from mono-functional devices with common functions, such as switch-on and return delay, through to multi-functional devices for every application with the ability to integrate up to 27 functions in a single device.

The 3RP25 time relays have a new enclosure design and its mono-functional devices with a width of 17.5mm offer the greatest space-saving in the control cabinet. The wide voltage range for direct current and alternating current (ac/dc) have also been expanded uniformly to 12V - 240V, enabling the number of device variants to be almost halved, minimising logistics and simplifying configuring and service.

The new series includes the necessary international certification for global applications. The new devices are also equipped with a watchdog function which is particularly effective for controlling clock times in cyclic sequences.

The variants with wear-free semiconductor output can be used effectively in applications with frequent, short switching operations, such as longitudinal feed in punching or embossing machines.

The product range encompasses removable terminals in widths of 17.5mm or 22.5mm and in the mid-term, will replace time relays of the 3RP15 range.
