DA-100 detects combustible or toxic gas leakage and transmits standard electric current output signal 4 ~ 20mA to be connected with various controllers such as gas leakage warning device (GMS-1000/1500/2000), PLC, DDC, or MMR for individual or integrated gas monitoring system(controller).
[ Features ]
ㆍ 4-20mA Transmitter: standard electric current output signal (4-20mA) enables a stable transmission even in long distance up to 2.5km.
