Item # 176B6010, Vari Speed® A2000 DC Motor Speed Controllers
Operating Conditions
AC Line Voltage:
Rated voltage ±10%
AC Line Frequency: 48 to 62 Hz
Elevation:
Up to 3,300 ft. without derating
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; 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
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
