G123-820 Setpoint and Ramp


The G123-820 is a command signal generator that produces a sequence of ramped commands suitable for use as an input signal to a Servo-Proportional Valve, for open loop control of a hydraulic cylinder or motor. Other applications include the provision of pre-set values for a closed-loop control system. User supplied logic inputs select the four front panel set points, output polarity and ramp off. This product requires a 24V DC supply.
