SSM24C User Manual

The IN3 digital input is designed for low speed digital input operation between 5 and 24 volts.
The diagrams below show how to connect them to various commonly used devices like sensors,
switches, relays, PLCs, etc.
Note: If current is flowing into or out of an input, the logic state of that input is low or
closed. If no current is flowing, or the input is not connected, the logic state is high or
open.
3.3.4 Programmable Output
The SSM24C 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
