New safety relay for monitoring machine speed and standstill at the same time

This device, which belongs to the range of Sirius 3TK28 safety relays, can simultaneously monitor three parameterizable limit values for downtime, setup speed and automatic speed. The device is set with menu guidance, for instance speed limits defined, via buttons arranged on the front of the device and an LCD display.

Diagnostics and status information are displayed in plain text with several LEDs to facilitate the early detection of faults, for example. This reduces downtimes and increases plant availability. There is one safe output and one signaling output for each of the three values that can be monitored. The user uses these values, for instance, to initiate measures to ensure continued operation of the plant in a safe state.

A complete protective door monitoring system with spring-loaded or magnetic locking tumbler mechanism is already integrated in the Sirius 3TK2810-1 speed monitor. No additional evaluation unit is thus required which not only saves costs, but also space, and the safety function has the same quality. The new safety relay is suitable for all standard sensors for speed monitoring and is available in the 24 V DC and 120 to 240 V AC/DC voltage versions.
