5.4 Analog Output
The CRLDS-1000 and CRLDS-CO2 detectors features a single configurable Analog output. During normal operation, the
device’s Analog output signal is proportional to the gas concentration measured, and can be selected from the following
options:
• 1 to 5 V
• 2 to 10 V
• 0 to 10 V
• 4 to 20 mA (default)
The CRLDS-1000 and CRLDS-CO2 detectors uses different voltage/current values to indicate different operating modes.
In normal operation, the gas concentration is indicated by the Analog output signal level. The relationship between
output signal level and gas concentration is shown below:
Gas Concentration 1-5 V 2-10 V 0-10 V 4-20 mA
Underrange 2 mA
0% 1 V 2 V 0 V 4 mA
50% 3 V 6 V 5 V 12 mA
100% 5 V 10 V 10 V 20 mA
Overrange 22 mA
