Delphian offers three different style controllers, all of which are ready to
configured in either a Rack/Panel Mount
Flexirack or Panel/Wall Mount
Zone Alarm Modules
Sage-CE Computerized Gas Monitoring System
A gas detection controller has a simple job - to continually monitor a single
point in space for combustible or toxic gases and give an alarm when an alarm condition
exists. Our Micro and DC controllers perform that job simply and reliably. Up to 32
individual controllers can be mounted in a standard 19" rack space 7" high.
Since sensor power is regulated in the transmitter module, little power is dissipated in
the controller. No cooling fans are needed, even with dozens of controllers in a totally
sealed box. Don't waste valuable control room space. Sealed relays are standard.
THE MICRO CONTROLLER
||The Micro Controller is fixed installation single channel and slides into the
Flexirack. It requires a compact one inch of panel space three
and one-half inches high. It is a simple design with few parts there there is less that
can go wrong. It is easy to maintain and repair. The controller uses a rugged analog meter
and has LED indicators for power, fail, high and low alarms, full 100% RFI shielding and
|Relays can be normally energized, or de-energized with manual or auto
reset. The system operates from a nominal 24 Vdc power supply or 115 Vac. A 4 to 20 mA
current output is standard with other outputs available.
Controller Part Numbers
||The DC controller is a smart two channel digital device which
displays alarms and concentrations of the gas(s) to be sensed.
Each channel can be configured independently and unlike other controllers, the two
channels are completely independent of one another.
Each channel provides three gas alarms, "LO", "HI", "HIHI"
and a "FAIL" alarm for combustible and toxic gases. (For Oxygen deficiency
detector heads, the gas alarms are "LO" "LOLO" and "HI".)
Each channel has four relays which can be energized or de-energized on alarm. The system
requires a nominal 24 VDC power supply. Different front colors are used depending upon the
|When an alarm is activated:
The display on the DC flashes between the gas concentration and the alarm words.
The output relay changes state. The relay can be wired to operate external
For toxic gas sensors the controller will read in parts per million and for
combustible gas detector heads it will read in % LEL. Oxygen sensors read in % gas.
