The Emerson IC694CHS392, also cataloged as the IC694CHS392 10-slot Serial Expansion Backplane, operates as a hardware component for expanding the input/output capacity of a primary controller rack via an expansion bus cable within the PACSystems RX3i control platform.

Model Configuration

The IC694CHS392 is configured as a standard 10-slot serial expansion baseplate utilizing high-speed serial backplane communication exclusively. It requires the leftmost slot to be dedicated to a compatible serial power supply module such as the IC694PWR331, IC694PWR330, or IC694PWR321.

Hardware Specifications

Engineering Characteristics

Designed for modular expansion, the backplane integrates a bus connector provision at its right end to facilitate daisy-chaining optional or additional expansion cables. System configuration relies on user-set integrated DIP selection switches located on the assembly. The unit maintains robust signal integrity across expansion distances up to 15 meters.

Installation and Electrical Integration

• Power Supply Placement: Insert a compatible serial power supply (IC694PWR331, IC694PWR330, or IC694PWR321) into the leftmost slot of the expansion base.
• DIP Switch Configuration: Properly set the integrated DIP selection switches before physical module installation and mounting.
• Hot-Swapping Prohibition: Ensure the system is completely powered down before swapping components; hot installation and removal of modules is strictly prohibited on this expansion backplane.
• Cabling and Daisy-Chaining: Link the base to the primary controller rack using specialized I/O expansion cables, utilizing the right-end bus connector for additional daisy-chained segments.
