WARNING! Plugs with free-wheeling diodes and LED indicators cannot be used with
current controlled power outputs. They interfere with the current control and can
destroy the output stage.
Switched inductances (relays and valve coils) which are connected to the same power supply
must always be provided with appropriate overvoltage protection directly at the coil.
The 15-poles terminal strip accepts connections of a 1.5 mm² conductor with ferrule.
Applications that require larger cross sections require mandatorily a junction box.
WARNING! Engage the terminal block ONLY with the panel switched off.

Connection
Supply
PIN 1
Power supply
PIN 2
0 V (GND) Power supply (ground).
0 V reference for PIN 9.
0 V reference for PIN 12 in EDM-M version B.
Connection
PWM output
PIN 3 / 4
Current controlled PWM output for the solenoid
Connection
Analog input
PIN 7
Reference (input) signal, corresponds with 0…10 V or 4…20 mA
PIN 8
0 V reference for the input signal
Connection
IO
PIN 9
Digital output for card status.
LOW: power output not enabled
HIGH: card ok, power out enabled
PIN 12
VERSION A
–
Digital input
Function depends on parameter
ENABLE
(INT|EXT)
EXT
=
Enable Input
.
This pin receives ENABLE signal from the PLC.
The current output is generated.
INT
=
no associated function. (Enable signal is generated by internal
logic)
VERSION B
–
Aux voltage output
It replicates PIN1 value. (0 V ref. PIN2)
PIN 13
Auxiliary voltage output for potenti10 V
PIN 14
Auxiliary voltage output for potentiometer -10 V
PIN 15
0V reference PIN 13 and PIN 14
