    Isolation
      AGB0 provides isolation of non-isolated inputs and allows multiple A2000 controls to be controlled by a single process signal. AGB0 also provides isolated open collector with adjustable time delay for current limit indication, and a speed follower output signal when used with a tachometer.

      AGB0 Isolation Option
      Isolation provides isolation for non isolated input command signals. Provides the A2000 with the ability to accept various process speed signals and isolated tachometer feedback inputs. Includes a minimum speed adjustment, range adjustment and run status LED.
      AGB0 Application Data
      Speed Signal Input:
      • 0-10 VDC (0-20 mA DC)
      • 1-5 VDC (4-20 mA DC)
      • 5K, 1W potentiometer (input impedance = 80K ohm)

      Run/Stop input:
      • Contact or solid state (NPN) switching device acceptable

      Tachometer input:
      • 20.8V/1,000 rpm
    Enclosure 7V/1,000 rpm
    Isolated open collector sinking output signal with adjustable time delay for current limit indication and a speed follower output signal when used with a tachometer. Allows multiple A2000s to be controlled by a single input signal.

    Adjustments:
    • Minimum speed
    • (0-50% of motor base speed)
    • Range adjust
    • (0-110% of motor base speed)
    • Limit Time Delay (0.2-2.0 sec)


    AGB0 Application Output Data
