Installation Guidelines
- The terminator plug must be installed exclusively on the final baseplate in an I/O expansion chain.
- Locate the "I/O BUS OUT" port on the right side of the last expansion baseplate.
- Insert the IC693ACC307 firmly into the 25-pin connector.
- Secure the connection by tightening the mounting screws on the D-shell connector to prevent vibration-induced signal loss.
- Always power down the PLC system before connecting or disconnecting I/O bus components to prevent electrical damage.
- Failure to install the terminator may result in "Loss of I/O Module" errors or failure of the CPU to recognize remote racks.
FAQ
What is the primary function of the IC693ACC307?
The IC693ACC307 acts as a bus terminator containing a resistor pack. It prevents signal reflections on the I/O expansion bus, which is critical for maintaining reliable communication between the main CPU and remote expansion racks.
Where should this plug be installed?
It must be installed on the "I/O BUS OUT" port of the very last baseplate in your expansion configuration.
Is this component compatible with all Series 90-30 racks?
Yes, it is designed for use with Series 90-30 CPU and expansion baseplates that utilize the 25-pin I/O bus architecture.
