The Wireless Receiver and Analog Output Modules can be mounted in snap 

track, DIN Rail or surface mounted.

SNAPTRACK MOUNTING

Push in the blue mounting tabs on the receiver and output modules.  These 

units will now fit into the board slots of 2.75” snap track. Insert the receiver at 

the far left of the snap track, then insert each analog output module and slide 

it to the left until its connectors are fully mated into the receiver or the next 

analog output module. You may attach up to 127 analog output modules to a 

receiver.  
If your output modules cannot fit in one piece of snap track, then mount 

another piece of snap track nearby and insert your additional modules. 

Connect wires from the right side of the first string of modules to the left side 

of the second string of modules on the second snap track. This configuration 

requires one or more Pluggable Terminal Block Connector Kits (BA/AOM-

CONN) for the extra wire terminations on the left and right side of the Analog 

Output Modules. Each kit includes 4 connectors. 

DIN RAIL MOUNTING

Push out the blue mounting tabs on the receiver and 

output modules.  These units will now snap onto DIN 

Rail. Catch the EZ mount hook on the edge of the 

DIN rail as shown in Figure 6. The rotate into place.
Attach the receiver at the far left of the DIN Rail, 

then attach each analog output module and slide it 

to the left until its connectors are fully mated into the 

receiver or the next analog output module. You may 

attach up to 127 analog output modules to a receiver.  
If your output modules cannot fit onto one piece 

of DIN Rail, then mount another piece nearby and 

attach your additional modules. Connect wires 

from the right side of the first string of modules to the left side of the second string of modules on the second DIN Rail. This 

configuration requires one or more Pluggable Terminal Block Connector Kits (BA/AOM-CONN) for the extra wire terminations 

on the left and right side of the Analog Output Modules. Each kit includes 4 connectors.

SURFACE MOUNTING

Push out the blue mounting tabs on the receiver and output modules.  Attach the 

receiver to the surface using four screws, one in each blue tab. Attach Analog Output 

Modules by placing each one against the surface and sliding it to the left until its 

connectors are fully mated into the receiver or the next analog output module. Attach 

each module to the surface with two screws, one in each blue tab. You may attach 

up to 127 analog output modules to a receiver.  
If your output modules cannot fit in one straight line on the surface, then mount a 

second string of modules nearby. Connect wires from the right side of the first string 

of modules to the left side of 

the second string of modules. 

This configuration requires one 

or more Pluggable Terminal 

Block Connector Kits (BA/AOM-CONN) for the extra wire terminations 

on the left and right side of the Analog Output Modules. Each kit 

includes 4 connectors.
