3.3.4 Programmable Output
The SSM23C drives feature one optically isolated digital output (OUT). This output can be set
to automatically control a motor brake, to signal a fault condition, to indicate when the motor is
moving or to provide an output frequency proportional to motor speed (tach signal). Or the output
can be turned on and off by program instructions like Set Output (SO). The output can be used to
drive LEDs, relays and the inputs of other electronic devices like PLCs and counters. The OUT+
(collector) and OUT- (emitter) terminals of the transistor are available at the connector. This allows
the output to be configured for current sourcing or sinking.
