Installation - Cardinal 225 Installation, Set-Up And Operation Manual

Logic Level Output
Your Model 225 indicator has logic level outputs that can be used to control peripheral devices
used to signal when the weight is within preset limits. Note that these outputs (defined on the
next page) are at logic level and cannot drive external devices directly. Solid-state relays can
be used to accept the logic level output from the 225 and in turn, drive the external device.
Output 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.
3. Slip the cable through the gland connector and into the enclosure.
4. Remove 2 inches of the cable outer insulation jacket
5. Next, remove 1/4 inch of insulation from each of the wires.
6. Connect each of the wires to the Remote Outputs terminal block (P15).
7. 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.
8. Repeat procedure until all wires are in place.
AC Output Relay Board(s)
The AC Output Relay Boards are mounted in an external junction box for use with the 225
Indicator. The RB4-ACOUT contains one board and supports four outputs (jumper selectable).
The RB8-ACOUT contains two boards and supports eight outputs. The relay board used in
both is (Cardinal p/n 8539-C062-0A). Connect the devices to be controlled as shown in Figure
No. 1.
The individual relays can be configured to be on (closed) or off (open) at weights under the
preset weight then switch at the preset weight from on-to-off or off-to-on by setting the under
weight condition to on or off during setup and calibration or setup review.

NOTE! All relays are the normally-open type that will open when power to indicator is lost.
