SO2 Gas Transmitter, RS485 Output Signal


The series of 485 main line gas detection alarm system adopts non-standard agreement or MOdBUS protocol for data collection and transmission. This fixed so2 gas detector alarm can detect gas concentraion in the spot and transfer gas signal to a control panel,when gas concentration exceed a preset alarm level,the panel will make alarm. It is with relay output to connected with an alarm light or fans,valves.

What's the differences among 2/3/4 wires connection?

In a 2 wire transmitter, one wire is the power source (+) and other one is the return Power (-) + Signal (mA).

In a 3 wire transmitter, two wires are used as a power supply (+) and (-) and the third one is used as Signal (mA).

In a 4 wire traansmitter, two wires are used for power supply and the other two wires are used for Signal (mA).
