6.4. Connection method of 3-wire type for Gas detector
■ When the gas detector is configured with power supply and 4-20mA output using 3 wires(V+, mA, V- ),
connect to the channel unit by the following method.
■ Connection cable should be configured with shield cable of CVVS or CVVSB of more than1.5sq.
[Figure 8. 3-wire connection method for gas detector]
■ Our company's detector models of the relevant method include TS-1100Ex, TS-2000Ex, TS-2100 Series,
TS-4000 Series, TS-4100P Series, TS-5100 Series, GTD-1000 Series, GTD-2000 Series, GTD-3000 Series,
and GIR-3000 Series.
6.5. Connection method of 2-wire type for Gas detector
■ When output of gas detector is configured using 2-wires(V+, V- ), connect to the channel unit by the following method.
■ nection cable should be configured with shield cable of CVVS or CVVSB of more than1.5sq.
■ Our company's detector models of the relevant method include TS-1100Tx, TS-2000Tx, TS-3000 Series, and
TS-3100 Series.
