MeloAuto-Trusted PLC & DCS Parts Supplier
The IC693CHS392F functions as a bus expansion baseplate for the Series 90-30 PLC system. This unit adds five additional I/O slots to your existing rack configuration. It connects to the main CPU rack through a dedicated expansion cable. Therefore, you can expand your control system without replacing the existing hardware.
Technical Specifications
We engineered this expansion baseplate for reliable operation in industrial environments. Its rugged metal construction provides excellent mechanical support for installed modules. Additionally, the unit includes a passive backplane with no active components.

Bus Architecture and Signal Flow
The IC693CHS392F provides a passive backplane for all installed I/O modules. This baseplate carries both power and data signals between modules simultaneously. It supports any combination of discrete, analog, and specialty modules. Consequently, you can build a flexible I/O configuration for your specific application needs.
Physical Design and Mounting
This expansion baseplate features a heavy-duty steel chassis for mechanical rigidity. Five module slots accept standard Series 90-30 I/O modules without any adapters. The unit includes built-in mounting tabs for panel or rack installation. Each slot has a plastic keying mechanism to prevent incorrect module insertion.
Cable Connection and Bus Extension
The IC693CHS392F requires a single 50-pin expansion cable to function. This cable carries the full I/O bus from the main CPU rack. You can locate this baseplate up to 50 feet away from the primary rack. Always use shielded cable for runs exceeding 25 feet to maintain signal integrity.
Energy State and Power Requirements
This passive baseplate does not contain any energy storage components internally. It draws all necessary operating power from the installed power supply module. The backplane distributes 5V DC to each occupied I/O slot equally. No battery backup exists on this unit for data retention.
