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
