Product description
Temperature limiter Senseca TB225-0-0-0-00-SIL
The Temperature Limiter TB225-0-0-0-00-SIL from Senseca (formaly Martens) is suitable for thermal process monitoring and securing the operating status in the event of a fault. Both thermocouples and Pt100 sensors, as well as analogue signals can be connected to the universal input. The temperature limiter TB225-0-0-0-00-SIL is SIL2-certified and has two relays, which can be configured independently of one another, and an analogue output that can forward the temperature value. The unit is controlled via the buttons on the front and the integrated graphic display. The display colour changes from white to red in case of an alarm.
