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.
■ When output of gas detector is configured with 2-wire(V+,V- ),
connect with the Channel Unit by the following method.
■ Connecting cable should be configured with shield cable of
CVVS or more than CVVSB 0.7sq.
■ Our company's detector models of the relevant method include
TS-1100Tx, TS-2000Tx, TS- 3000 Series, and TS-3100 Series.
