Installation of Application Modules
The IOM-1 and PCM application modules allow for memory expansion, I/O
expansion and more complex motion programming capability. The IOM-1 and PCM
application modules (Programmable Control Module) attach to the front of the drive
amplifier with two locking arms. All electrical connections (except I/O) are made via
the 48 pin connector.
NOTE: For programming and operation of the PCM Modules, see "PCX
VERSION 6.X OPERATORS" Manual P/N 400240-01.

PCM Modules I/O Connections
All PCM application modules are equipped with 8 inputs and 4 outputs which are
optically isolated for +10 to +30 vdc operation. Each input and output has 2 screw
terminals associated with it to provide for either sinking or sourcing operation. The
first 8 pairs of designated terminals are inputs and the last 4 pairs of terminals are
outputs. The outputs are capable of sinking or sourcing 200 mA. It is the users
responsibility to limit the output current to less then or equal to 200 mA.
Adding a IOM-1 or a PCM module will double the I/O capabilities of the 525 PMC.
The number of input lines are increased from 8 to 16 and the number of output lines
is increased from 4 to 8.
The inputs and outputs allow for proper timing and coordination between the
drive's motion and other machine control functions. The inputs and outputs
typically are connected to the machine's programmable logic controller (PLC) or
