TKG- CO- 1 X Y Z C - R–TH/T
 
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)
 
Y: relay dry contact output
         0: no dry contact output
         1: 1xdry contact output
         2: 2xdry contact outputs
 
Z: Communication interface
         0: no communication interface
         1: Modbus RS485
         9: BACnet communication
 
C: 24VDC/VAC power supply
 
R: co range
         001: 0~100ppm (default)
         002: 0~200ppm
         005: 0~500ppm
 
-TH(option)  temperature & RH detection and display
          No –TH indicates without temperature & RH detection and display
 
- T(option)  temperature detection and display
 
-NL(option)  No LCD display, only for the CO detector without the relay output. 
 
For example: TKG-CO-1101-001-TH indicates the CO detector with 1X0~10VDC linear output and Modbus interface. CO range:0~100ppm. It has temperature and humidity detection and display.
