ANALOG INPUT OPTION: Model 2900A
for applications up to 1 horsepower
These controls are easily interfaced to low level analog circuitry.
Motor speed and direction are determined by amplitude and polarity
(5 volts full scale) of input signal. Input signals are isolated
from the motor and power line with a minimum isolation voltage of
1500 VDC. This reduces the possibility of grounding, noise or safety
problems. In addition, a failsafe circuit de-energizes the motor
if the input control power is not present.
