Gas Module Introduction
FAD gas module with two/three wire TTL/0-20mA/RS485 output, integrates toxic gas sensor + transmitter board. Adopting imported advanced electrochemical gas sensors, it has features of high accuracy, long lifetime, high stability and high anti-interference. The module is designed to prevent circuit reversed connection, high voltage, high current and lightning.

Gas Module Feature

- Long lifetime imported advanced electrochemical sensors

- High accuracy op ams, power supply IC, stable and sensitive

- Detect low or high concentration toxic gases precisely

- High anti-interference ability

- Over range protection, reversed polarity protection and lightning protection

- Low power consumption with a standard 4-20mA two/three-wire signal output

- Interface: pump, diffusing, flange, flange thread types

- 12-36VDC operating voltage
