Safety First with our Safety-TL4896

The next innovation of the GHM GROUP in the field of industrial safety technology: The Safety-TL4896 is the first safety temperature limiter for panel mounting, offers a number of cost and resource savings:

  • Since he does not sit on the DIN rail, he works directly as an indicator. An additional display for the STL signal from the DIN rail is superfluous
  • The integrated analog output for the temperature signal eliminates the need for another measurement chain for the signal to the PLC or SCADA world.
  • The direct execution of the reset function on the device eliminates the need for an additional element in the control panel.
  • Configuration via the buttons and the front display - without additional software.
  • The pre-alarm, which triggers an alarm before reaching the limit value, thus avoiding possible shutdown. This avoids unnecessary process downtime.
  • The unit is certified to EN 14597, EN 61508 and SIL2.
