TTSIM-1A
Leak Detection Module
The
TTSIM-1A
is a primary sensor interface module with the capacity to monitor up to 150 m (500ft) of sensor cable. The output is via relay contacts and serial data. When liquid is detected, the TTSIM-1A unit indicates the leak with an LED, and switches a relay to provide local voltage-free contact closure. The TTSIM-1A can also communicate to a host monitoring system such as a TraceTek TTDM-128 or directly to a PLC or other host system using standard protocols. The low cost of the TTSIM-1A makes it economical to build very robust systems with many small independent sensing cable segments. No field calibration is required.
FEATURES
- Voltage-free contacts for alarm signaling.
- LEDs to indicate power, leak, cable trouble, and communication status.
