The AD-9120 digital servo-amplifiers are designed for remote mount to control appropriate Jordan Controls
The AD-9120 digital servo-amplifiers are designed for remote mount to control appropriate Jordan Controls actuators. A microprocessor-based control and an IGBT-based intelligent power module is used to drive the actuator to perform bidirectional positioning. The "rapid setup" feature allows actuator setup using push-button switches (no potentiometers or jumpers). Self-diagnostics and prompts are available through an on-board visual display. Additional features include:
•Overcurrent protection
•Adjustable deadband
•Improved diagnostics and self test features
•Vacuum fluorescent display
•Optimum motor efficiency
•Isolated, two wire, 4-20mA output
•Visual outputs for loss of signal (LOS) indication and increase/decrease driving direction
•Customer adjustable gain, zero and span
•Loss of signal selection and changeable in the field
•Interchangeable powerstage with the AD-7800
•Form C fault relay output
