Models Guide

TKG- CO- 1 X Y Z C - TH-R

1: wall mounted with the external sensor in an adown probe

X: analog output
          0: no analog output
          1: 1x0~10VDC linear output(default)
          2: 1X4~20mA linear output (default)
          3: 1X0~10VDC output and can be switch to 4~20mA (just for only one analog output)
          4: 1x0~5VDC linear output (default)

Y: relay dry contact output
        0: no dry contact output
         1: 1xdry contact output
         2: 2xdry contact outputs

Z: communication interface
        0: no communication
        1: Modbus RS485 interface
         9: Bacnet MS/TP interface

C: 24VDC/VAC power supply

-NL(option) No LCD display, only for the transmitter which only has one analog linear output.

-TH(option) temperature & RH detection and display
         No –TH indicates without temperature & RH detection and display

R: CO range
     005: 0~500ppm (default)
    001: 0~100ppm
   002: 0~200ppm

For example: TKG-CO-1101C-TH-001 indicates the CO detector with 1X0~10VDC linear output and Modbus interface. CO range:0~100ppm. It has temperature and humidity detection and display.
