Onguard FG8800-1060 Addressable Field Node Monitors Four Channels of Contact Inputs
The FG8800-1700 4-20MA microprocessor based node accommodates four independent gas sensors. The node contains an LED that blinks for power on status. Each channel has its own unique address and can be treated as an individual input for the system. Color bar graphs indicate the gas concentration levels at the control panel. Real time %LFL and loop current measurement are also displayed on the screen. Each channel accommodates three set point locations. The choice to disable any channel is implemented through the program. The node and its associated field wiring are continuously supervised and interrogated through the control panel.
