ANALOG INPUT: Model 2767A
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. Programmable jumper used for ±10V analog input applications.
