The PMC 6 Relay / 4 Input I/O Module is a member of
Intellitec's Programmable Multiplex Control family. It
works in combination with the PMC CPU and other
standard, semi-custom, or custom I/O modules.
The 917 module provides six undedicated relays for
switching floating signals. Each relay can carry up to 10
amps of current. There are diagnostic LED’s for each of
the relay circuits. These LED’s will light when the
respective relay is closed.
In addition to the six output diagnostic LED’s on the
outputs, there is also one that indicates the failure of
communications. This LED will light in the event of loss of
signal.
There are four input connections for rocker, limit, or
sensor switches. Each individual input can be configured
as either a low side switch to ground, or a high side switch
to battery. There are four jumpers on the board that can
be set to have the input be a high side or low side input.
