ATS109TD Fixed Type Nitrogen Dioxide Gas Leak Detector

Fixed Type Nitrogen Dioxide Gas Leak Detector single channel digital control modules are designed to supervise and display the satus of a single intergal or remote sensor Model ATS 109TD assembly. Model ATS 109TD is housed in a NEMA 4 x wall mount enclosure or Ex -proof enclosure. Model ATS 105M Single channel controllers interface with industry standred two or three wire 4-20mA sensor or other standred voltage / current sensor transmitters and provide the user with concentration display and two independent adjustable alarms levels. The Graphics display can read the concentration. LEDs on the front panel provide indication of all three alarms.

• The alarm relays can be programmed to be either latching or non-latching and to activate either as a rising or failing alarm. The relays are SPDT Form C type rated at 5 Amps. to provide direct alarm action, reducing the need for interposing relays . Local Alarm devices can be connected to the configurable on board alarms.The Fail safe supervisory provides a reliable indicaiton that the Monitor is fully operational. The "Fail Safe" design monitors the input power and sttaus of the Power suppy for the e amplifiers.A failure of any one of these functions illuminates a " Fault" Light Emitting Diode.
