Connection and Wiring
Do not connect power to the AXB-REL8 until the wiring is complete. If you are using a 12 VDC power supply, apply power to the AXB-REL8 only after installation is complete.
Preparing captive wires
To connect the wiring into a captive-wire connector:
1.Strip 1/4 inch off the wire insulation for all four wires.
2.Tin 2/3 of the exposed wire.
3.Insert each wire into the appropriate captive-wire connector up to the insulation.
4.Tighten the captive screws to secure the fit in the connector.
Wiring guidelines
The AXB-REL8 requires 12 VDC power to operate properly. The Central Controller supplies power via the AXlink cable. The maximum AXlink wiring distance between the Central Controller and AXB-REL8 is determined by power consumption, supplied voltage, and the wire gauge used for the cable. The following table lists wire sizes and the maximum lengths allowable between the AXB-REL8 and the Central Controller, based on the maximum power consumption rating of 170 mA (all eight relays ON).
The maximum wiring lengths for using AXlink power are based on a minimum of 13.5 volts available at the Central Controller's power supply.
Wiring Guidelines at 170 mA
Wire Size | Maximum Wiring Length |
| |
18 AWG | 690.42 feet (210.43 m) |
| |
20 AWG | 436.80 feet (133.13 m) |
| |
22 AWG | 272.33 feet (83.00 m) |
| |
24 AWG | 171.66 feet (52.32 m) |

If the AXB-REL8 is installed farther away from the control system than recommended in the above table, connect a 12 VDC power supply to the AXlink connector on the AXB-REL8 rear panel (see Wiring AXlink with Optional 12 VDC Power Supply).
Connecting the Wiring
The following paragraphs describe wiring connections for using the AXlink and relay connectors.
If using power from AXlink, disconnect the wiring from the control system before wiring the AXB-REL8.
