AGBØ

AGBØ 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.

AGBØ 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:
• 20.8V/1,000 rpm; 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)

AGBØ Application Output Data
Current limit indication (overload) with adjustable ignore time.

Output:
NPN transistor capable of switching 24 VDC at 250 mA

Speed follower output signal usable with armature or tachometer feedback

Output:
0 - 10VDC = 0 - 100% motor base speed
Maximum current: 10 mA
