2.3.2 Analog Input
The Analog Input Interface Board (
) provides sixteen separate 4-20 mA inputs in two rows
identified as JP1 though JP16. The board plugs into a Carrier Board to complete an Analog Input Stack.
The function of the Analog Input board is to provide connectivity for up to sixteen 4-20 mA loops. The
board receives the analog signal inputs and converts them to digital data communicating with the SBC.
The board includes:
(1) Individual field connections for analog sensor power and signal
(2) Individual jumpers to select 2, 3 or 4 wire operation
(3) Field connection for Trouble Relay
(4) Factory installed wire and ribbon cable connections for power and inter-stack and SBC
communication
Each analog loop connector has four positions to provide 24VDC power and isolated 4-20 mA signal
wiring. A terminal jumper located behind each connector is factory installed for two or three wire loop
connection and can be moved to a four wire position.
Analog Stacks can be installed in any stack position in the controller and must configured for the
corresponding stack position number on the Carrier Card rotary switch. A maximum of two Analog Input
Stacks are allowed per controller. The Analog Board also provides also provides a programmable SPDT
Relay intended for use as a local Trouble Relay.
