OC_Output_1-4_Common_Return
PWR-IN
Common power return pin for discrete, isolated, outputs
1 to 4
Note: 5v supply limitation:
Note that the 5v supply that is provided both on pin 7 in Port J6 and Port J9 are internally limited
to 0.5A (both pins together). This is in order to protect the amplifier from short to GND.
Future firmware version of the amplifier will be able to detect and report this fault and to disable
the 5v supply until the fault is fixed. Currently, the current will be limited, but the detection of
this limit and the shutting off of the 5v supply is not supported yet.

▪
The interface circuit is identical for all outputs 1 to 4 in Port J6 and outputs 5-8 in Port
J8.
▪
Each output can be programmed (by a software parameter) to act as a current sourcing
output (up to 300mA) or as a current sinking output (up to 500mA).
▪
Common power is shared by all 4 outputs.
▪
Common power can go up to 45 volts. Yet, typical usage should be limited by 36v.
