Produktbeschreibung

general information:

The STL50 safety temperature limiter is used where ever thermal processes must be monitored and the system must be transferred into a safe operational state in case of fault. If the permissible temperature limit value is reached, or if a fault occurs within the permissible temperature range on the monitoring equipment (sensor break, sensor short-circuit, failure of a component part in the device, fault in the software, failure or
inadmissible value of the supply voltage etc.), the STL50 switches off without delay. The alarm contact is activated, the LED ALARM on the front panel and the back-lighting of the display light up, and the error cause is indicated as plain text on the display. In addition, there is a 24 V DC signal present on the terminals 16-17 for an external alarm signal. Alternatively, the device can be reset using an external contact. In addition, the STL50 optionally has a programmable analog output with up or downscaling function, as well as a precontact.
