Amplifier cards are the control electronics that drive proportional and servo hydraulic valves. They take a command signal from a PLC or controller and supply the precise current to the valve solenoid, so flow and pressure follow the setpoint. Twin Hydraulics Engineering supplies amplifier cards and electronic driver modules across Malaysia.
Many older Bosch Rexroth cards are now obsolete. If your original card is no longer available, send us the card type code and the valve it drives, and we will advise on a replacement or retrofit option. We can also support installation, commissioning and setting of the card on site.
See also our proportional directional control valves and the valve repair service for complete support of proportional and servo systems.
