Four-channel gas measuring controller for continuous
monitoring and warning of toxic, combustible and
refrigerant gases and vapours.
The Gas Controller GC-04 can monitor up to 4 analog
gas transmitters with 4 to 20 mA signal. Five alarm
thresholds are adjustable per channel. The alarms are
transmitted by up to 5 relays with change-over contact.
Two analog outputs (4 to 20 mA) are free adjustable.
Via expander modules EP-04 the Gas Controller can be
extended to up to 24 analog gas transmitters, 20 alarm
relays and 12 analog outputs.
