The PMC Output Modules 00-00844 are members of Intellitec's
Programmable Multiplex Control family as well as the 160 Channel
Multipoint Switching System. They work in combination with the PMC CPU
or the 160 channel IPX master and other standard, semi-custom, or
custom I/O modules. These modules provide solid-state outputs with the
capability of dimming lights.
The modules provide power fusing, switching, and distribution.
Switching is accomplished via long life, field effect transistors
instead of relays. Each output will handle
10 Amps. The total module current is limited by the on the following
page.
The approximate module dimensions are 7.0" X 6.250" X 1.875" (16.2mm X
15.9mm X 4.8mm). The 844 module can be set for module addresses, A-P. “I
squared rule" It should be installed in a protected environment, inside
the vehicle. Using the chart on the next page, set the dip switches 1-4
to address the module.
The 844 modules provide the ability to dim lights from any Intellitec
multiplex keypad. With the PMC system, a momentary push button can be
used if it is connected to a PMC input. These modules come in two
versions. The 00- 00844-120 works with the 160 Channel Multipoint
Switching System.
This module dims the lights using pulse width modulation or PWM.
Variable power is applied to the load by quickly turning the power on
and off. By varying the duty cycle we can vary the intensity of the
lamp.
By adjusting the dip switch, it is possible to select the channels that
will operate to dim lights
