TTSIM-3/4 Sensor Interface Modules

The Raychem TraceTek TTSIM-3 monitors up to 350 m (1150 ft) and TTSIM-4 up to 1500 m (5000 ft) of Raychem TraceTek sensing cable. When liquid is detected, the TTSIM 3 or 4 units indicate the leak with an LED, and switches one or two independently programmable relays to provide local voltage‑free contact closure. The TTSIM-3/4 can also be used as a stand alone leak detection alarm unit or communicate to a host monitoring system such as Raychem TraceTek TT‑TS12, TTDM‑128 or directly to a PLC or other host system using standard protocols. TTSIM-3/4 are the direct replacements for TTSIM-1/1A/2.
