Order No. 30-3001-197
Version A
Your warranty is effective for 18 months starting on the
date the system is shipped.
Before You Begin
You can connect one or more EMX modules to most Infinet
controllers that have an expansion port. The particular controllers are covered in the ACC EMX Modules Configuration
Guide (also enclosed with this product).The configuration
guide also tells how many inputs and outputs are allowed for
any a particular controller. Before you proceed, be sure the
controller allows modules and the number and type of modules you plan to use.
Warning
Be sure wiring and installations comply with local, state,
and national electrical codes.
Figure 1 shows the EMX 140 module.
Dimensions
Each EMX 140 module is approximately 7.98 × 6.13 × 1.95 in.
Power Requirements
The first module receives power from the controller and
operate on 24 to 26 VDC. You can add an additional EMX
140 module or other EMX modules other than an EMX
140 if you have an external power supply source of 24
VDC and properly connect the modules to it. See the ACC
EMX Modules Configuration Guide for more information.
The EMX 140 consumes up to 110 mA at 24 VDC.
Environmental Requirements
The EMX 140 operates in the same environment that any
Infinet controller operates in.

The EMX 140 and 141 have pneumatic output channels.
The EMX 140 has two, the 141 has one. These outputs automatically convert the electronic signal to pounds per
square inch (psi) and operate in the range of 0 to 20 psi.
Each channel requires 20 to 30 psi of supply air.
The EMX 142 and 143 do not have expansion port connectors, but have input terminals (INA and INB) that you
wire to analog output terminals on your controller. The
EMX 142 has two, the 143 has one. The analog input terminals receive current from current outputs on your
controller and each has a 0 to 20 mA control signal.
Install the EMX 140
1. Unpack
Be careful when unpacking the unit or units to not damage
the packaging material—you must reuse it if you ship the
product back for repair.

2. Connect EMX 140 or 141 to Infinet
Controller
Connect the module to the Infinet controller as outlined in
the steps that follow.
Caution
Be sure you disconnect the Infinet controller’s AC power
source before you connect any modules.
1.Look at the bottom panel of your Infinet controller. On
that panel is an expansion port in approximately the
center of the panel.
2.Look at the EMX 140 module. Notice that it has a
connector on the top and on the bottom. Plug the top
connector into the Infinet controller.
3.If you are connecting more than one EMX 140 module
to your Infinet controller, connect the second one to the
bottom of the first. If you connect more than one
module, you must use an external power supply (see
details later).
4.Set the BOARD switch to 1 on the first EMX 140 on the
controller, and the BOARD switch to 2 on the second
EMX 140. If you do not plan to connect more than one
EMX 140, you should set the BOARD switch to 1.
Never set two modules of the same model number to the
same board number.
5. Wire EMX 142 or 143 Outputs
For the EMX 142 or 143, you need to run some extension
wire between the output on the controller and the input terminals on the module. You wire from the controller output
current (I) terminals to the module terminals as follows:
1. Slip the appropriate extension wire under the INA screw
on the EMX module and tighten the screw down on it.
2. Slip the ground extension wire under the RET screw on
the EMX module and tighten the screw down on it.
Figure 2 illustrates the wiring for the outputs.

3. Extend the wire to the controller; then slip the
appropriate wire under the I screw of an output on the
controller and tighten the screw down on it.
4. Extend the ground wire to the controller; slip it under
the RET screw and tighten the screw down on it.
5. Repeat the process for the INB connection .
6. Connect the External Power Supply
3. Connect EMX 140 or 141 Outputs
You do not have to wire the pneumatic outputs to the EMX
140 or 141; they are built-in. Instead, you connect air tubes
to the tubes associated with each output, one on the left side,
the other on the right. For each output, you connect one tube
to SUPPLY AIR and the other to OUT.
4. Connect EMX 142 or 143 to Infinet
Controller
The EMX 142 and 143 do not have expansion port connectors. So, how do you connect them to the Infinet? You
wire the analog outputs from the controller to the input
terminals on the module—INA and INB. The module
then converts those analog outputs to pneumatic outputs.
See the section called Wire the EMX 142 or 143 Outputs.
(if necessary)
If you are installing multiple modules, you may need an
external power supply. To determine what you need, refer
to the ACC EMX Modules Configuration Guide. If you
are installing an EMX 142 or 143, you require external
power, since you are not connecting the module directly
to an Infinet controller via its expansion port.
Figure 3 shows where you connect the external power
supply to the 2-pin Berg type connector on the EMX 140.

You change the jumper position only on the module or modules connected to the external power supply, not on any other
modules.
Note
You need to change the jumper position only on the module(s) actually connected to an external power supply. Never
change the jumper position of other modules.

Troubleshoot
For information on how to assign point numbers and program the outputs, see the Andover Controls Infinity CX
Programmer’s Guide.
7. Reposition Jumper on One Module
The Berg type connector immediately to the right of the
external power supply connection has a jumper that you
reposition to indicate you are using external power.
Figure 4 shows the jumper in the two possible positions,
one for the internal power supply, the other for the external.
