Description
Intellitec PMC Output module 00-00844-510
The PMC 844-500 & 844 510 modules are member of Intellitecs Programmable Multiplex Control family and work in conjunction with the PMC CPU. The 844 series provide 10 solid state PWM outputs that can be used with any Intellitec multiplex keypad for light dimming.
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.

It should be installed
in a protected environment, inside the vehicle.

address the module.
PWM PROVIDES VARIABLE POWER
(PULSE WIDTH MODULATION)
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. The 00-00844-500 and 00-00844-510 work with
the PMC 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.
When set as a non-dimmable output, the outputs will
operate as any other PMC output. To keep the output on, it’s
channel must be on. If the output is set to be a dimmable
output, the output will latch on at the output module. To turn
the output on, all that is required is that it’s channel be turned
on momentarily. When the channel comes on, the output
turns on and latches. When the channel turns off, the output
remains latched until the channel turns on again, at which
time the output turns off.
If the lighting output channel is B3 and a momentary push
button is placed at D5 you could write a boolean such as
B3=D5. When momentary button D5 is pressed and
released output B3 will turn on at 100% intensity and remain
on even though switch channel D5 is off. When D5 is
pressed and released a second time, output B3 will turn off.
This happens because we latch the output on and off at
the module. When button D5 is pressed and held, the
output will begin to ramp up, increasing the lamp
intensity. When the button is let go, the lamp will remain
at that intensity. Pressing and holding the button a
second time will cause the intensity to begin ramping
down. When the button is released, the lamp will
remain at that intensity. Pressing and releasing the
button quickly will cause the output to toggle off. If
power has been maintained at the module, the output
will remember it’s last intensity setting.
This module works with the non-programmable
Multipoint Master. This module works in a similar
fashion to the 844-500 and 510, except that when it’s
outputs are not set for dimming they will latch on and off
just as the dimmer outputs do. With the Multipoint
Master and Intellitec programmable momentary push
button switches 00-00841-XXX, a switch is set for the
same channel as the output. When the switch turns the
channel on, the output latches on. When the switch
turns the channel on again, the output latches off.
Using the GUI and setting a switch for BL/MR (back
light/Master Reset), instructs the switch to turn all 10
outputs off when the switch is held for 3 seconds.

next page for dip switch settings.
