AXB-REL8 Relay Controller

Overview

The AXB-REL8 (FG5774) controls closure-activated devices, acting as an eight-channel

relay control port on the AxLink bus.

Installation

Setting the DEVICE DIP Switch

Note: Use the DIPSwitch 2.0 application available for free download from AMX to quickly

figure out DIP Switch settings for all types of DIP Switches.

Set the device number on DEVICE DIP switch, located on the front of the AXB-REL8. The

device can be 1 of the 255 devices in an Axcess control system. The device number must

match the device assignment in the Axcess program. Device numbers are assigned into the

following three segments:

• Cards 1 through 95

• Boxes 96 through 127

• Panels 128 through 255

Set the device number by setting the device DIP switches. The device number is the total of

all of the switches in the ON position, and take effect by cycling the power.

Wiring

Preparing and Connecting Captive Wires

1. Strip 0.25 inch of wire insulation off all wires.

2. Insert each wire into the appropriate opening on the connector according to the wiring

diagrams and connector types described in this section.

3. Tighten the screws to secure the wires. Do not tighten the screws excessively; doing

so may strip the threads and damage the connector.

Wiring Guidelines

The interface requires a 12 VDC power to operate properly. The interface uses a PSN2.8

power supply. The Central Controller supplies power via the AxLink cable or external 12 VDC

power supply.

The maximum wiring distance between the Central Controller and interface is determined by

power consumption, supplied voltage, and the wire gauge used for the cable.

The table below lists wire sizes and maximum lengths allowable between the REL8 and

Central Controller. 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.

AxLink Data and Power Connections

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.

Wiring AxLink With Optional 12 VDC Power Supply

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, 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).

Front Panel Components

AxLink Status indicator AxLink LED (green and blinks to indicate AxLink

communication activity and power:

• Full-Off indicates no power is being received or the

controller is not functioning properly.

• One blink per second indicates power is active and

AxLink communication is functioning.

• Full-On indicates there is no AxLink control or activity, but

power is On.

Device DIP switch An eight-position DIP switch is used to set the device

number for the AXB-REL8.

Relay LEDs 1-8 (Red) Illuminate when associated relay is closed. Relay LED's

should match panel control function.

Rear Panel Components

AxLink connector Four-pin captive wire receives power and information via

the AxLink bus and AxLink system controller.

Relay contacts Eight (normally -open) isolated two-pin relay contacts

1 A @ 28 VAC or VDC:

• Relays 1-4 can share a common if use jumper "A" pins

with a tab strip

• Relays 5-8 use discrete commons (wire commons

individually)
