Andover Controls ACC EMX 150 Installation Manual

ACC EMX 150
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 150 module is approximately 6.13 × 4.88 × 1.52 in.
Power Requirements
The first two modules receive power from the controller
and operate on 24 to 26 VDC. You can add additional
EMX modules other than an EMX 150 if you have an ex-

ternal 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 150 consumes up to 55 mA at 24 VDC.
Environmental Requirements
The EMX 150 operates in the same environment that any
Infinet controller operates in.
Output Characteristics
The voltage output has 5 mA maximum output over the
range of 0 to 20 VDC. The input impedance of the device
being controlled can be no less than 4000 Ω .
Resolution of each voltage output is 0.100 V or 100 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 750 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 100 µ A or 0.1 mA.
Install the EMX 150
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
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.
