High Power Optoisolated Outputs
The DMC-40x0 has different interconnect module options, this section will describe the 500mA optically isolated
outputs that are used on the ICM-42x00.
The amount of uncommitted, optoisolated outputs the DMC-40x0 has depends on the number of axis. For
instance, 1-4 axis models come with a single bank of 8 outputs, Bank 0 (DO[8:1]). 5-8 axis models come with an
additional bank of 8 outputs, Bank 1 (DO[16:9]), for a total of 16 outputs.
The wiring pins for Bank 0 are located on the ICM-42x00 I/O (A-D) 44 pin HD D-sub Connector and the pins for
wiring Bank 1 are located on the ICM-42x00 I/O (E-H) 44 pin HD D-sub Connector. See the the Appendix for your
ICM: A11 – ICM-42000 (-I000), A12 – ICM-42100 (-I100), or A13 – ICM-42200 (-I200) for pin-outs.
Description
The 500mA sourcing option, referred to as high power sourcing (HSRC), is capable of sourcing up to 500mA per
output and up to 3A per bank. The voltage range for the outputs is 12-24 VDC. These outputs are capable of driving
inductive loads such as solenoids or relays. The outputs are configured for hi-side (sourcing) only.
Electrical Specifications
Output PWR Max Voltage 24 VDC
Output PWR Min Voltage 12 VDC
Max Drive Current per Output 0.5 A (maximum 3A per Bank)
Wiring the Optoisolated Outputs
The output power supply will be connected to Output PWR (labeled OPWR) and the power supply return will be
connected to Output GND (labeled ORET). Note that the load is wired between DO and Output GND. The wiring
diagram for Bank 0 is shown in Figure 3.6 and Bank 1 in Figure 3.7. See the “I/O 44 pin HD D-sub Connector” for
your specific ICM module in the Appendix for the correct pin-outs.
