ICM-3300 Interconnect module for CDS-3310
The ICM-3300 Interconnect module breaks out the 15 pin and 37 pin connectors on the
CDS-3310 into screw-type terminals to allow for easier wiring of external devices. It
also provides opto- isolation for all digital I/O except the following: brake output, output
compare, reset input and digital input 8. Additionally, it converts four of the CDS-3310’s
standard digital outputs into high-power (500mA @ 24V) sourcing outputs.

Opto Isolation Settings
The ICM-3300 module allows for opto- isolation on digital inputs and outputs. This
includes the dedicated I/O including limits, homes, and abort. The limits and home
are powered by Limit Switch Common. Digital inputs 1-7 and the Abort Input are
powered by Input Common. The digital outputs are also optically isolated including
the Error and Amp- Enable outputs. The first four outputs are configured for hi-side
drive only (sourcing). The supply vo ltage must be connected to output supply
voltage, and the supply return must be connected to output return.

Input Isolation
Opto-isolation of the general purpose inputs and the abort input is used by powering
the Input Common line. The limit switch and home inputs are powered by Limit
Switch Common. Shown below is the circuit diagram for the isolated inputs.

Output Isolation
The first four digital outputs on the ICM-3300 are set up as high current isolated outputs
and are configured for High Side (Sourcing) operation. The outputs are capable of
sourcing 500 mA per output. Digital outputs 5-10 and the AmpEnable/Error output are
low power opto-outputs. The output will be at the voltage that is supplied to the
OUTSUP pin. Up to 24 VDC may be supplied to OUTSUP.
The resistor packs RP10, RP11 and RP12 allow for the configuration of the active state of
the outputs. For example when you issue the SB1 command, the polarity of the resistor
pack will determine whether the output is turned on or off.
