GE Fanuc IC693CHS392E Series 90-30 PLC Expansion Baseplate

Product Overview

The GE Fanuc IC693CHS392E is a 10-slot expansion baseplate engineered for the Series 90-30 PLC system. Designed to extend system I/O capacity beyond the main CPU baseplate, it allows up to 10 discrete, analog, or option modules to be mounted in a single rack. The IC693CHS392E requires a Series 90-30 Power Supply unit installed in its left-most slot to deliver power across the backplane and connects to the primary CPU rack or preceding expansion rack via a standard I/O bus expansion cable. Weighing approximately 1.0 kg (2.2 lbs), this panel-mount baseplate ensures long-term industrial durability and seamless modular scalability.

Technical Specifications

Key Design & Hardware Features

• 10-Slot High-Density Capacity: Maximizes rack density by offering 10 full-featured slots for I/O modules, motion control modules, and communication interfaces.
• Dual Expansion Bus Connectors: Equipped with female 25-pin expansion bus ports (IN and OUT) to allow daisy-chaining multiple expansion racks up to maximum system cable limits.
• Dedicated Power Supply Position: Features a left-hand dedicated power supply slot to generate backplane 5 VDC and 24 VDC relay power for installed modules.
• Industrial Panel Installation: Rugged metal backing plate ensures mechanical rigidity and proper ground connection when secured to control panel sub-panels.

Installation & Engineering Guidelines

1. Rack Addressing: Set the rack DIP switch on the IC693CHS392E baseplate to assign a unique rack address (Rack 1 through 7) so the CPU can correctly address all installed I/O points.

2. Bus Termination: If the IC693CHS392E is the final expansion rack in the daisy chain, attach a bus terminator plug (IC690ACC901) to the OUT expansion connector to prevent bus signal reflection.

3. Power Supply Selection: Ensure the power supply module inserted into the expansion baseplate can provide sufficient 5 VDC current to meet the cumulative power consumption of all 10 module slots.

Frequently Asked Questions (FAQs)

Q1: Can a CPU module (e.g., IC693CPU370) be installed directly into the IC693CHS392E baseplate?
A1: No. The IC693CHS392E is an expansion baseplate. CPU modules can only be installed in slot 1 of a Main Baseplate (such as the IC693CHS391).

Q2: How many IC693CHS392E expansion racks can be connected to a single Series 90-30 CPU system?
A2: Depending on the specific CPU model used, a Series 90-30 system supports up to 7 expansion baseplates daisy-chained together using expansion cables.

Q3: Does the IC693CHS392E expansion rack require its own separate power supply module?
A3: Yes. Each expansion rack requires a dedicated Series 90-30 Power Supply unit installed in the left-most power slot to supply power to the local backplane.
