Description
The Denison Hydraulics S20-11958 is a Jupiter HI/IQ Driver Card designed for electronic control of variable-displacement hydraulic pumps, hydraulic actuators, and other devices with position feedback. It can also control the speed and direction of a hydraulic servo motor. The driver uses a linear bidirectional current-control architecture and can accept voltage or current-loop commands, potentiometer signals, or active signal sources. It is specifically identified as a driver for Denison Gold Cup high-response hydraulic pump control applications.
The driver supports multiple command-input configurations, command reversal, positive and negative ramp settings, emergency shutdown control, and closed-loop control when used with the appropriate Jupiter options hardware. The documented S20-11958-0 version is identified as the Jupiter HI/IQ Driver Card, while the supplied listing identifies the item as S20-11958 and used condition.
