product description
General information:
The STL4896 safety temperature limiter is used wherever thermal processes have to be monitored and the system has to 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, software error, failure or inadmissible value of the supply voltage etc.), the STL4896 switches off immediately.The alarm contact is activated, the LED ALARM on the front panel and the background illumination 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 STL4896 has a programmable analog output with up- or downscaling function, as well as a precontact.
