Delphian Corporation DC Controller 372-795-01

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 gas type.
