Optoisolated Outputs - Galil Motion Control DMC-21 5 Series User Manual

Optoisolated Outputs

The ICM-20105 allows for optoisolation for the digital outputs (DO). The ICM outputs are 500mA sourcing outputs.
The amount of uncommitted, optoisolated outputs the DMC-21x5 has depends on the number of axis. 1-4 axis
controllers have a single bank of 8 outputs, Bank 0 (DO[8:1]). 5-8 axis controllers have an additional bank of 8
outputs, Bank 1 (DO[16:9]).
Description
The outputs are capable of sourcing up to 500mA per output and up to 3A per bank of outputs. The voltage range
for the outputs is 12-24 V
outputs are configured for hi-side (sourcing) only.

Wiring the Optoisolated Digital Outputs
The output power supply will be connected to Output power (Output PWR) and the power supply return will be
connected to Output GND (Output RET). Note that the load is wired between DO and Output GND. The wiring
diagram is shown in Figure A7.4.
