SSM23Q/IP Hardware Manual
3.3.4 AIN Input
The SSM23Q/IP drives have an analog input (AIN) which can accept a signal range of 0 to 5 volts.

power external devices such as potentiometers. It is not the most accurate supply for reference,
for more precise readings use an external supply that can provide the desired accuracy.
3.3.5 Programmable Output
The SSM23Q/IP 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

Diagrams of various connection types follow.
Do not connect the output to more than 30 volts. The current through the output terminal
must not exceed 100mA.
