Optoisolated Outputs
The DMC-41x3 has several different options for the uncommitted digital outputs (labeled as DO). The default
outputs are 4mA sinking which are ideal for interfacing to TTL level devices. Additional options include 25mA
sinking (lower power sinking, LSNK), 25mA sourcing (low power sourcing, LSRC), and 500mA sourcing outputs (high
power sourcing, HSRC). Please refer to your part number to determine which option you have.
The amount of uncommitted, optoisolated outputs the DMC-41x3 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 J5 - I/O (A-D) 44 pin HD D-Sub Connector (Female) and the pins for wiring
Bank 1 are located on J8 - I/O (E-H) 44 pin HD D-Sub Connector (Female). See the Pin-outs in the Appendix for
more details.
Wiring diagrams, electrical specifications, and details for each bank and output type are provided below.
4mA Sinking Optoisolated Outputs (Default)
Description
The default outputs of the DMC-41x3 are capable of 4mA and are configured as sinking outputs. The voltage range
for the outputs is 5-24 VDC. These outputs should not be used to drive inductive loads directly.

Wiring the 4mA Sinking outputs
With this configuration, the output power supply will be connected to Output PWR (labeled OPnB) and the power
supply return will be connected to Output GND (labeled OPnA), where n denotes 0 or 1 referring to Bank 0 and
Bank 1 respectively. Note that the load is wired between Output PWR and DO. The wiring diagram for Bank 0 is
shown in Figure 3.6 and Bank 1 in Figure 3.7. Refer to Pin-outs in the Appendix for pin-out information.
