• With screw terminal connections
• Potted loose cables without connectors
• Status display by means of LED
ELECTRONICS SD7 CHARACTERISTICS
Digital controller module for regulating position, pressure or
volume flow including integrated amplifier.
FEATURES
• Controller mode selectable: pressure, position, speed
• Solenoid current regulated, with superimposed dither
• Command and feedback values as voltage or current
• Up to 7 digital inputs and up to 4 outputs
• Optionally with fieldbus (CANopen, Profibus DP, HART)
• Housing for dome rail mounting
• SSI interface
• Analog output
