IC693CHS398 GE Fanuc 5-Slot Expansion Baseplate | New & Original Stock

GE Fanuc IC693CHS398 Series 90-30 I/O Expansion Baseplate

Configured for specific technical tasks in Series 90-30 PLC platforms, the GE Fanuc IC693CHS398H (IC693CHS398 I/O Expansion Baseplate) provides direct physical/electrical execution. The hardware operates as a local bus extension chassis containing 5 dedicated I/O/option module slots and 1 unnumbered power supply slot. Lacking an integrated central processing unit slot, this component routes logic commands and system power backplane lines from a primary CPU rack through a 25-pin D-shell female expansion connector to facilitate remote physical point concentration.

Hardware Specifications

Profinet / EtherNet/IP Deterministic Networks and I/O Density Scaling

The IC693CHS398 functions as a baseline physical footprint to accommodate structured I/O density scaling across a localized area. When data frames are gathered by input modules in slots 1 through 5, the parallel data packets are pushed across the internal chassis bus to the master CPU via shielded cabling systems. While this chassis uses standard parallel bus architecture, the combined point matrix interfaces directly with modern upstream Profinet or EtherNet/IP deterministic networks through compatible communication bus controllers. All modules residing within this frame preserve native firmware flash compatibility with the supervisory CPU, enabling predictable bit allocation mapping across the distributed layout.

Frequently Asked Questions

Q: What is the maximum number of IC693CHS398 expansion baseplates that can be attached to a single controller system?

A: The maximum configuration limit depends entirely on the model of the supervising CPU module. Systems running a modular CPU 331, 340, or 341 support a maximum connection limit of four expansion baseplates. Systems utilizing a higher-tier CPU 350 processor can scale up to support a maximum limit of seven expansion baseplates connected to the same master node.

Q: Can modules be hot-swapped within slots 1 through 5 while the baseplate power supply is turned on?

A: No. The internal backplane lines of the Series 90-30 system do not possess active isolation or current-limiting controls for on-the-fly card changes. Attempting to pull out or plug in any module while the unnumbered power supply slot is actively running can disrupt parallel bus processing logic and cause processor faults or electrical hardware failure.

Field Installation Guidelines

• Chassis Panel Fastening: Isolate all primary system power supplies before physical attachment. Secure the baseplate frame vertically onto a rigid metallic enclosure backpanel via the integrated pre-drilled flange holes. Confirm a solid metal-to-metal connection to support optimal structural alignment.
• Rack Addressing Selection: Prior to clicking modules into place or supplying electrical current, configure the dedicated chassis identification address using the local onboard DIP switch bank. Duplicate rack address indices on the same physical link will stop the processor from scanning.
• Cabling Integrity and Shielding: Link the 25-pin expansion bus port to the upstream baseplate via continuous-shield cables (models IC693CBL300, 301, 312, 313, or the terminated 302 variant). Total cumulative cable segment lengths across the chain must not cross the maximum threshold of 50 feet (15 meters).
• Common Ground Connection: Attach the frame grounding lug directly to the central panel cabinet copper ground bar using a short, thick-gauge green conductor. Proper common grounding prevents stray electrical noise from corrupting data on the +5 VDC logic bus lines.
