The Safety-TL4896 safety temperature limiter monitors thermal conditions in industrial and thermal process plants. It fulfils all requirements on the redundant electrical configuration for safe switching in all systems for process heat in accordance with EN 746.

Safety temperature limiter: technically on the safe side

The Safety-TL4896 meets the specifications of EN 14597, EN 61508 and SIL2 as a safety temperature and as a safety temperature monitor. It enables direct mounting on the switch panel or the switch cabinet door. There is no need for an additional display on the top-hat rail. Configuration of the Safety-TL4896 (STL) takes place directly via the buttons on the front display. Additional software is not necessary. With the integrated analogue output for the temperature signal, an additional measuring chain for the signal for the PLC or SCADA world can also be omitted. The pre-alarm provides an early warning of critical situations and thus prevents unnecessary downtimes.
