Supply
Power supply (see technical data)
0 V (GND) Power supply (ground).
Attention, PIN 8 and PIN 11 are connected internally. PIN 11 is used as the GND potential
for the command and feedback signals.
Reference voltages output
Reference output voltage (8 V).
PWM output
Current controlled PWM outputs for solenoid A.
Current controlled PWM outputs for solenoid B.
Analogue input signals
Command signal input, range 25...75 % of reference value (supply voltage).
Reference value, supply voltage of the setpoint device (8... 30 V).
Potential connectors of the inputs, have to be connected to 0 V (GND)
0 V (GND) reference, e.g. for the signal inputs.
Digital inputs and outputs
Enable Input:
This digital input signal initializes the application.
The output and the READY signal will be activated.
By deactivating error signals are reset.
READY output:
ON: Module is ready, no errors are detected
OFF: ENABLE (PIN 15) is deactivated or an error is detected.
