Multiple event tracking capability for up to 128 independent sensor circuits.
Summary relay contacts, LED status lights, LCD information display at the TTDM-128 panel.
Standard external interface modes include: dry contacts, and RS232/RS485 modbus communication. A 4-20 mA analog output option is available.
Event history accessible from the front panel or via serial port to identify type of event, time, location, and other parameters for all sensor events or user adjustments and interventions.
Layered password protection for setup changes.
Adjustable sensitivity and selectable measurement units.
Universal power supply for 120/240 Vac 50/60 Hz (24 volt option available).
Non-volatile memory for event history, setup and network configuration.
Complete remote operation and monitoring through modbus communications or using optional TT-SUPERVISOR Windows software.
Easy setup and simple operation
The TTDM-128 module directly monitors up to 1500 m (5000 ft) of sensor cable and a network of up to 128 remote TraceTek modules. The remote modules may be a combination of sensor interface modules (TTSIM), relay modules (TT-NRM) or additional TTDM-128 modules. With its networking capability, the TTDM-128 provides tremendous fl exibility in terms of system layout options and monitoring capability. When liquid is detected on any of the sensors, the TTDM-128 sounds an alarm, closes relay contacts, turns on a front panel LED and displays the circuit identifi cation and location of the leak on the alphanumeric display. The leak detection event is logged to a nonvolatile event history fi le. All status and event information is made available via the front panel keyboard or RS232/RS485 modbus digital communication to a host computer, PLC or plant/building automation system. Each sensor circuit detects, locates and tracks leaks independently from any other circuits connected to the TTDM-128. There is no loss of sensitivity and no re-mapping required after an initial leak is detected. A simple map showing where the sensors are installed is the only field calibration requirement.
NON-LOCATING WATER LEAKAGE SYSTEM
The FG-A alarm unit, connected to a TTK FG-ECX, FG-ACX or FG-HC2 sense cables, is designed for the leak detection of liquids. The presence of a conductive liquid on the sense cable triggers an audible
and luminous alarm, and activates dry contacts on the FG-A alarm unit.
This detection system fits in perfectly with a safety and protection system.
Its two dry contacts ensure fault control and transfer back to a centralized management system.
ZD-18 panel can be used for the leak
protection of small computer rooms or
technical service areas. Main application
areas including: under-floor air conditioning
units, over-head fan coil units, hot water
radiator units, sump tanks, drip trays, etc.
The system allows immediate detection of
conductive (water, acid & alkaline) or nonconductive
(hydrocarbon fuel or organic
solvent) by applying different type of liquid
