Output Isolation - Galil Motion Control CDS-3310 User Manual

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 Amp Enable/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.
