ATTENTION:
Never open the housing.
Never remove the circuit board from its housing.
Never crimp or cut cables while they are connected
to powered equipment.
The module is not provided with additional protection
against short circuit, therefore it is recommended to
use a power supply with the correct specifications.
Mordomus shall not be liable for any damages
resulting from the use of our equipment outside the
specifications and/or for a purpose other than that
intended.
When using a low cross section cable there might be
voltage drops that could force the module into under-
voltage protection mode.
Do not connect power supplies with an output current
greater than 4A.
The power supply shall never be connected to the
modules at the extremities of the bus as in
IAC88
Do not connect voltages greater than 10V to the
inputs of the iAC88.
Do not connect alternating current to the inputs of the
iAC88.
The power supply shall be connected to a central
module in order to distribute the power to the
remaining modules. For larger installations add as
many power supplies as required, always respecting
a uniform distribution. View

MDiBus connection: To connect the module to the MDiBus a CAT
HW 1.0
6 UTP cable with RJ45 connectors according to EIA568A or
EIA568B standards must be used.
15VDC Power supply: It is recommended to use the iPSE154
power supply. The iAC88 module can source its power from other
nearby modules through the MDiBus cable.

Enrollment:
To enroll the iAC88 module proceed as follows:
1.
Make sure that the iAC88 is powered by a suitable
power supply
.
2.
In the Mordomus software access the menu
Configurations
Modules/Addresses.
3.
On the iAC88, press and hold the addressing button
for at least 1sec. The green LED will blink slowly
until the addressing is complete.
4.
The iAC88 should be added automatically to the list
and the green LED should stop blinking.
Analog Input types: Each analog input can be defined to read
voltage (0-10V) or current (4 – 20mA). To select 4-20mA place
the jumper on the corresponding pins
jumper (factory default).
Analog Input settings: Delta expressed in percent, defines
the necessary input voltage variation to be considered a new
valid reading. This option is configurable in the Mordomus
Software.
Analog
Input
settings:
seconds/minutes, defines rate at which readings are taken.
This option is configurable in the Mordomus Software.
