Product Introduction

The GE IC694CHS392 10-Slot Serial Expansion Backplane is a high-performance backplane designed for use with the GE PACSystems RX3i programmable automation controller family. It provides an efficient platform for connecting up to ten I/O and communication modules in a single rack configuration, offering both reliability and scalability for industrial control applications.

This backplane serves as a critical component in large automation systems, allowing for expansion beyond the primary CPU rack. Through its built-in serial expansion port, the IC694CHS392 enables seamless communication between the main rack and remote or auxiliary racks, ensuring consistent data flow and synchronized operations across distributed control systems.

Built to meet the demands of modern industrial environments, the backplane features a durable structure, gold-plated connectors for signal integrity, and intelligent grounding to minimize noise interference. Its design allows easy installation, maintenance, and module replacement, supporting high system uptime and flexibility for future upgrades.

FAQ 

1. What is the primary function of the IC694CHS392 backplane?
   It serves as a 10-slot expansion platform for connecting additional I/O and communication modules to a PACSystems RX3i controller.

2. How does the backplane communicate with the main RX3i rack?
   It uses a dedicated serial expansion interface connected via an expansion cable to the primary CPU rack.

3. Can the IC694CHS392 support both I/O and communication modules?
   Yes, all slots are universal and can accommodate a mix of I/O, communication, and special function modules.

4. What power supply modules are compatible with this backplane?
   It supports standard RX3i power supplies that provide 5 VDC backplane power up to 2.0 A.

5. Does this backplane support redundancy or hot standby configurations?
   Yes, when used with a compatible RX3i CPU and redundancy modules, it supports redundant system architectures.

6. What is the isolation level between logic and field circuits?
   The backplane provides optical isolation to protect control logic from electrical noise and voltage transients.

7. Can the IC694CHS392 be mounted in any orientation?
   It is recommended to mount it vertically or horizontally on a panel or rack to ensure optimal cooling and accessibility.

8. What happens if the expansion cable is disconnected during operation?
   Communication with the modules on that rack will be lost, and the CPU will generate an expansion fault until the connection is restored.

9. Is there a limit to how many expansion racks can be added to an RX3i system?
   Yes, the number of expansion racks is limited by the CPU’s expansion capability, typically up to 7 racks depending on configuration.

10. Does the backplane require special configuration in the software?
    Yes, it must be defined in the RX3i configuration software to assign slot addresses and module types correctly.
