500mA Sourcing Optoisolated Outputs (HSRC)
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 V
DC
. 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 V
DC
Output PWR Min Voltage 12 V
DC
Max Drive Current per Output 0.5 A (not to exceed 3A per Bank)
Wiring the 500mA Sourcing Optoisolated Outputs
With this configuration, the output power supply will be connected to Output PWR (labeled OPnA) and the power
supply return will be connected to Output GND (labeled OPnB) , where n denotes 0 or 1 referring to Bank 0 and
Bank 1 respectively. Note that the load is wired between DO and Output GND. The wiring diagram for Bank 0 is
shown in Figure 3.12 and Bank 1 in Figure 3.13. Refer to Pin-outs in the Appendix for pin-out information.
