AMX AXB-REL8 Manual De Usuario

Connect the control system's AXlink connector to the AXlink connector on the rear panel of the 

AXB-REL8 for data and 12 VDC power as shown in FIG. 3.     

Connect the control system's AXlink connector to the AXlink connector on the rear panel of the 

AXB-REL8 as shown in FIG. 4.      

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).

After set-up is complete:

Check continuity of relay wiring.

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

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

Insert relay wiring terminals into AXB-REL8.

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.
