Emerson E2 Manuel D’Utilisation

There are five I/O Network boards that may accept 

inputs: the MultiFlex, the 16AI, the ARTC, and the 8IO 
Combination Input/Output Board. Wiring an input to these 
boards requires three steps:

1.

Connect the sensor’s signal wires to the two ter-
minals of an input point.

2.

Set the input type dip switch that corresponds to 
the point being connected.

3.

If necessary, connect the power lead of the sensor 
to one of the 5V or 12V power terminals.

An input point connector on a MultiFlex, 16AI, and 

16AIe board consists of two terminals, as shown in Figure 
9-1. One of these terminals, labeled “SIG”, reads the sig-
nal from the sensor, while the other, labeled “0v” is where 
sensor’s ground and/or cable shield wire is connected.

On a 16AI, terminals are numbered 1-32, starting with 

the first terminal of point 1 and ending with the last termi-
nal of point 16. The even-numbered terminals of a 16AI 
are always where the signal voltages are connected. The 
sensor grounds and cable shields are connected to the odd-
numbered terminals.
8IO and ARTC Boards

On an 8IO board, the two terminals of every point are 

labeled “-” or “+”. The ground wire is always connected to 
the “-” terminal, and the signal wire is connected to the 

“+” terminal.

On the ARTC board, the input and output points are 

predefined and are labeled accordingly.

Specific wiring types are required for each type of sen-

sor used with E2. 
All Analog Temperature Sensors and Air Flow Sen-
sors

Temperature and air flow sensors are to be wired with 

shielded, 2 conductor, at least 22 GA wire (Belden # 8761 
or equivalent).
All Pressure Transducers, Humidity Sensors, and 
Refrigeration Transducers

Pressure and refrigeration transducers and humidity 

sensors are to be wired with shielded, 3 conductor, at least 
22 GA wire (Belden #8771 or equivalent).
Dewpoint and Light Level Sensors

These sensors are to be wired with shielded, 4 conduc-

tor at least 22 GA wire (Belden # 8729 or equivalent).

An input type dip switch must be set for each input 

point. Input type dip switches are located in the switch 
banks labeled S1 and S2 on the MultiFlex, 16AI, and 
switch bank S4 on the 8IO.

The input type dip switch tells the input board whether 

or not the sensor connected to the point requires a DC sup-
ply voltage in order to operate. If the sensor requires DC 
voltage, the dip switch should be set to the DOWN posi-
tion. If the sensor does not require power, or if it uses AC 
power, the dip switch should be set to the UP position. Dip 
switches for unused points should be set to the UP posi-
tion.

The dip switch positions for each specific sensor type 

is shown in Figure 9-2.
