1.3.1 Main Board

The main board houses the microprocessor, and supporting electronics for controlling the
operation of the Model Mini-ICS Analyzer. The main board receives the sensor signal and flow
switch inputs, and provides the control and display functions of the analyzer.

1.3.2 Relay Board

The Relay Board houses relay contacts for all of the Alarm and Control features of the Mini-ICS.
The relays are mapped discretely to each alarm or control function to provide electrical outputs for
reporting, and process control use.

1.3.3 Power Supply

The power supply board is designed to take 110/220 VAC, 50/60 Hz (90-264 VAC, 47-63Hz). as
input. The supply is internally fused directly on the board. An optional 24VDC (10-30 VDC) power
supply is available for installations where a DC voltage is required to power the Model Mini-ICS. A
12VDC battery-backup power input (battery not provided) is also provided to act as a backup in
case of main power failure.

1.3.4 Display Board

The Display board is designed to generate a digital indication of the concentration of Oxygen, and
