Optically Isolated Remote Inputs - Cardinal 225 Installation, Set-Up And Operation Manual

OPTICALLY ISOLATED REMOTE INPUTS

The Model 225 has seven (7) programmable inputs that may be used to remotely (up to 100
feet) initiate various functions within the indicator. These inputs are accessed via a terminal
block (P17) on the back of the Main PC board. The 7 inputs are defined on the following page.
Remember that the input must be connected to GND to initiate the function.
Input Cable Installation
1. If the rear panel of the indicator has been removed, proceed to step 2. Otherwise,
remove the 14 acorn nuts securing the rear panel to main housing
2. Loosen a gland connector for the cable and slip the cable through the gland connector
and into the enclosure.
3. Remove 2 inches of the cable outer insulation jacket and then remove 1/4 inch of
insulation from each of the wires.
4. Connect each of the wires to the Remote Input terminal block (P17).
5. To terminate a wire, use a small flat blade screwdriver and press down on the release
bar for the terminal. Insert the wire into the terminal opening. Remove the screwdriver,
allowing the release bar to return to its original position, locking the wire in place.
6. Repeat procedure until all wires are in place.
AC Input Relay Board(s)
The AC Input Relay Board(s) are mounted in an external junction box for use with the 225
Indicator. The RB4-ACIN (115 VAC) or RB4-ACINV (230 VAC) contain one board and
supports 4 inputs (jumper selectable). The RB8-ACIN (115 VAC) or RB8-ACINV (230 VAC)
contain two boards and supports seven inputs that are jumper selectable. The relay board
used in the 115 VAC versions is Cardinal p/n 8200-C324-0A. The 230 VAC version uses relay
board Cardinal p/n 8200-C324-1A. Connect the devices as shown in Figure No. 2.
