PAM-195-P-S3
4.4
Input and output signals
Connection
Supply
PIN 7
Power supply (see technical data)
PIN 8
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.
Connection
Reference voltages output
PIN 12
Reference output voltage (8 V).
Connection
PWM output
PIN 3 / 4
Current controlled PWM outputs for solenoid A.
PIN 1 / 2
Current controlled PWM outputs for solenoid B.
Connection
Analogue input signals
PIN 9 / 10
Command (input) signal (W), range -
100…100 % or 0… 100 % corresponds with 0…10 V or
4…20 mA. Other signal ranges can be scaled.
PIN 14 / 13
Feedback input
(actual pressure), range 0… 10 V or 4… 20 mA corresponds with 0… 100 %.
PIN 11
0 V reference for the signal inputs.
Connection
Digital inputs and outputs
PIN 15
Enable Input
:
This digital input signal initializes the application.
The output and the READY signal will be activated.
By deactivating error signals are reset.
PIN 6
Direction input:
Switching direction (changing solenoids).
PIN 5
READY output
:
ON:
Module is ready, no errors are detected
OFF:
ENABLE (PIN 15) is deactivated or an error is detected.
