ACC EMX 151
Installation Guide
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 con-
trollers 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 mod-
ules you plan to use.
Warning
Be sure wiring and installations comply with local, state,
and national electrical codes.

Dimensions
Each EMX 151 module is approximately 6.13 × 4.88 × 1.52 in.
Power Requirements
The first module receives power from the controller and
operates on 24 VDC +/–15%/–5%. You can add addition-

al EMX modules other than an EMX 151 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 151 consumes up to 70 mA at 24 VDC.
Environmental Requirements
The EMX 151 operates in the same environment that any
Infinet controller operates in.
Output Characteristics
You can wire the outputs as either voltage or current. The
voltage output has 2.5 mA maximum output over the
range of 0 to 10 VDC. The input impedance of the device
being controlled can be no less than 4000 Ω .
Resolution of each voltage output is 2.44 mV.
The current output has a 0 to 20 mA control signal. The
input impedance of the device being controlled can be no
greater than 1000 Ω .
The circuitry that produces the 0 to 20 mA signal acts as a
"current sourcing device." It sources the current to ground.
Resolution of each current output is 4.88 µ A.
Accuracy of voltage and current is +/–0.1 % of the range
of the output.

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 to the Infinet Controller
