DESCRIPTION:

The SERIES 1100 MOTOR CONTROLS are half-wave, regenerative (four quadrant) units that control the speed and direction of motor torque of shunt wound or permanent magnet (PM) DC motors, with outputs ranging from 1/6 to 1.0 horsepower.

These controls are designed to be easily interfaced to low level analog circuitry or standard currentloops. Input signals are opto-isolated from the motor and power line circuits with a minimum isolation voltage of 1500 VDC. This eliminates the possibility of grounding or noise problems.

Internal switches allow users to field select any of the following input ranges: ±100 MVDC, ±5 VDC, 4–20 mA, 10–50 mA. A failsafe circuit de-energizes the motor if control power is not present.

The Series 1100 motor control units are of open frame construction, suitable for OEM use in user provided enclosures. The aluminum mounting bracket serves as a heat sink for the power semiconductors. Inputs and outputs are connected by plug-in barrier strips or by solder eyelets.
