CMD5B1 Greystoneenergy máy dò khí CO Greystoneenergy Vietnam
CARBON MONOXIDE DETECTOR
The CMD series carbon monoxide detector uses an electrochemical sensor to monitor the carbon monoxide level and outputs a factory calibrated 4-20 mA, 0-10 Vdc, or Modbus signal. Optionally, the device may be configured with an alarm relay.
PRODUCT HIGHLIGHTS
- 0-300PPM for analog and 0-500PPM for Modbus units.
- Analog outputs, 4-20mA or 0-10Vdc factory selectable
- Modbus RTU communication
- Coverage area of 700m2
- Optional form C relay with jumper selectable alarm point.
