Working theory： |
| |
GN8020-E Toxic gas detector first sample the signal from sensor,then deal the signal with the internal data processing, final output the consistence of ambient air by the signal such as 4～20mA , Mod-bus digital frame.
The GN8020-E can use in system with our company's GN90000-B、GN90000-P、GN90000-F、GN90000-A、GN90000-S gas controller. Otherwise, through Linkage Output of relay, the GN8020-E can be joined with the host of fire control, and cut-over fire control system immediacy. |
