FIG. 4 Wiring AXlink with Optional 12 VDC power supply

Use a 12 VDC power supply when the distance between the control system and AXB-REL8 exceeds the limits described in the Wiring Guidelines at 170 mA table on page 4, or the power supply current capacity cannot accommodate the 170 ma (max) draw of the AXB-REL8. Make sure to connect the GND and +12 VDC wire on the AXB-REL8 AXlink connector end. Do not connect the optional +12 VDC power supply wire to the control system's power supply side of the AXlink connector (FIG. 4).

Checking the installation

After set-up is complete:

1.Check continuity of relay wiring.

2.Check cable numbers and wiring, interfaces and sources against supplied documentation.

3.Install tab strips to jumper between shared commons and clip off excess tabs.

4.Insert relay wiring terminals into AXB-REL8.

Relay connections

The relay specification is 1 A @ VAC or VDC. FIG. 5 on page 6 shows the relay wiring diagram for the AXB-REL8. The dotted lines are used to indicate commons. Install supplied tab strips to jumper between shared commons. Clip off excess tabs and bend strip up, away from other wiring.
