There are the following three methods for wiring a Pulse I/O Module.
• Using Connector-Terminal Block Conversion Units
Connector-Terminal Block Conversion Units are used when using normal I/O, quick-response
inputs, interrupt inputs, PWM outputs, or pulse outputs to stepping motors or other manufacturer's
Servo Drives.
• Using Servo Relay Units
Servo Relay Units are used when using OMRON's Servo Drives.
• Directly Connecting a Self-made Cable with a Connector
A self-made cable with a Connector can be used to directly connect the I/O.
