CO controller with BACnet RS485

Short Description:

Model: TKG-CO Series

Key words:
CO/Temperature/Humidity detection
Analog linear output and optional PID output
On/off relay outputs
Buzzer alarm
Underground parking lots
RS485 with Modbus or BACnet

 

Design for control carbon monoxide concentration in undergroung parking lots or semi underground tunnels. With a high quality Japanese sensor it provides one 0-10V / 4-20mA signal output to integrate into PLC controller, and two relay outputs to control ventilators for CO and Temperature. RS485 in Modbus RTU or BACnet MS/TP communication is optional. It displays carbon monoxide in real time on the LCD screen, also optional temperature and relative humidity. The design of external sensor probe can avoid internal heating of the controller from affecting measurements.
