Signal description
PIN 22 +
PIN 24 -
Power supply
: 10… 30 VDC:
For safety-related applications, the output stage
can be deactivated thanks to the separate power supply inputs.
PIN 17 + 19
Solenoid current output A
PIN 18 + 20
Solenoid current output B
Connection
Signals modified from the standard (A and I version)
PIN 15
0… 10 V / 4… 20 mA output with the scaled position demand value
PIN 16
0
… 10 V / 4… 20 mA
17
output with the scaled position actual value
