CONTROL ELECTRONICS

For the control of proportional valves, electronic control devices are required. They control
the solenoid current on the valve and thus guarantee a highly sensitive, low-hysteresis
valve control by means of Pulse Width Modulation and a superimposed dither signal. The
control devices are equipped with a microprocessor and can be adjusted using the intui-
tive parameterisation software PASO. This extends the functionality and allows for flexible

utilisation in a control system.

AMPLIFIER ELECTRONICS SD7 CHARACTERISTICS
Digital amplifier module for controlling one or two solenoids.

FEATURES
• Control of one 4/3-way spool valve or two 1-solenoid
valves
• Control via solenoid current with dither signal
• Command values as voltage or current
• Up to 7 digital inputs and up to 4 outputs

• Optional with fieldbus (CANopen, Profibus DP, HART)
• Housing for top-hat rail mounting

CONTROLLER ELECTRONICS SD7 CHARACTERISTICS
Digital controller module for controlling position, pressure or

volume flow including integrated amplifier.

FEATURES
• Controller modes selectable: pressure, position, speed
• Control via solenoid current with dither signal
• Command and feedback values as voltage or current
• Up to 7 digital inputs and up to 4 outputs

• Optional with fieldbus (CANopen, Profibus DP, HART)
• Housing for top-hat rail mounting
• SSI interface
• Analogue output

MINIATURE AMPLIFIER PD3 CHARACTERISTICS
Digital amplifier module for controlling a proportional valve.

PD3 is an electronics unit with cable connection. In the MPS

version, it is firmly mounted on a solenoid.
FEATURES
• Housing of protection class IP67
• Command value as voltage or current
• IO-Link interface
• Bluetooth interface
• Parameterisable by App, PASO Software or IO-Link
• Optional with fieldbus (CANopen or J1939)

• Housing with cable connections or mounted on the solenoid
