P1: analog outputs (analog-out option / U4 present).
Counting from top
1VAO+Supply-out when U1 is present.
Supply-in when no U1 present: 10..15V
41
2AO0outAnalog 0..10V output from opamp
42
3AOGNDAnalog output ground. Has to be either:
connected to FGND and jumper P12 shorted and R73 shorted
or
separate, no jumper "5V Out - 5V In", external 5V supply is needed for U7 to function on jumper "5V In" pin relative to GNDA
43
4AO1outAnalog 0..10V output from opamp
44
5AOGNDAnalog output ground.

Counting from top
1VAO+Not used
51
2AO0outPWM output, 5V CMOS logic, 10mA absolute max current
52

P7: Digital outputs.
Counting from top
1VDO+Supply in11..35V has to be supplied for digital outputs to function.
Design idea: wiring emergency-stop between field power supply and DO+ pin guarantees no output will be on when e-stop is triggered
61
2DO0outPositive logic digital outputs, capable of 0.625A per channel.
Switching resistive, inductive and capacitive loads.
Short circuit, overload, overvoltage, undervoltage, thermal, ESD protection.
Maximum current limited, high immunity.
