The IC695CHS016 is a high-capacity universal backplane from the PACSystems RX3i family, originally designed by GE Intelligent Platforms and now supported under Emerson Automation. This backplane provides sixteen (16) slots for hosting a wide range of modules, including CPUs, power supplies, I/O units, and communication adapters. Its dual-bus design incorporates both PCI and serial bus architectures. Consequently, the GE Fanuc IC695CHS016 offers exceptional flexibility by supporting both modern RX3i modules and legacy Series 90-30 components. This makes it an ideal choice for system upgrades or mixed-technology installations.
The IC695CHS016 backplane operates on an isolated +24 Volts DC input. It draws 600 mA at 3.3 VDC and 240 mA at 5 VDC internally, with this power supplied by the RX3i power supply module. The backplane includes a terminal strip (TB1) with Terminal 7 for the isolated 24VDC input and Terminal 8 for the isolated ground. Additionally, an integrated grounding bar simplifies installation and enhances electrical safety.
For physical dimensions, the IC695CHS016 measures 141.4 mm (H) x 602 mm (W) x 147.3 mm (D). In inches, that equals 5.5 x 23.7 x 5.8 inches. The recommended wire size for field connections ranges from 14 to 22 AWG, accommodating most standard wiring practices.

The GE Fanuc IC695CHS016 is built for durability in industrial environments. It requires installation inside an enclosure with a minimum rating of NEMA/UL Type 1 or IP20 (per IEC60529). For more demanding conditions, an enclosure rated up to IP54 is recommended to protect against dust and water splashes.
Proper clearance is critical for thermal management. Specifically, you must maintain a minimum of 102 millimeters (4 inches) of free space on all sides of the backplane. This clearance allows natural convection cooling to dissipate heat effectively. The backplane supports horizontal mounting only, so vertical installation is not permitted.
Installing the IC695CHS016 requires careful planning and adherence to safety practices. First, mount the backplane securely to the subpanel of your chosen enclosure using appropriate fasteners. Ensure the subpanel is flat and rigid enough to support the weight of all installed modules. Second, connect the isolated 24VDC power leads to Terminal 7 (positive) and Terminal 8 (ground) on the TB1 terminal strip. Use 14–22 AWG wire for these connections.
Next, install the required power supply module into the designated slot. Note that some power supplies, such as AC units, may occupy two adjacent slots. Therefore, plan your slot allocation accordingly. After installing the power supply, you can insert CPU, I/O, and communication modules into the remaining slots. The IC695CHS016 supports hot-swapping, so you can replace or add modules without shutting down the entire system. This feature significantly reduces maintenance downtime.
Finally, connect the integrated grounding bar to the enclosure's earth ground. This step is essential for safety and electromagnetic interference suppression.
The GE Fanuc IC695CHS016 backplane accepts a broad range of modules. These include RX3i CPUs, power supplies, analog and digital I/O, and specialty option modules. Additionally, it supports legacy Series 90-30 I/O modules through the serial bus interface. This backward compatibility protects existing investments and simplifies migration paths.
For larger systems, the IC695CHS016 includes an interface for local expansion. You can connect additional expansion backplanes to host more modules while maintaining a single unified bus. This scalability makes the backplane suitable for both medium-sized applications and large, distributed control systems.
1. Which modules are compatible with the IC695CHS016 backplane?
This backplane supports all RX3i PCI-based modules and legacy Series 90-30 I/O modules. It also hosts CPUs, power supplies, and communication adapters.
2. Can I mount the IC695CHS016 vertically?
No, the IC695CHS016 supports horizontal mounting orientation only. Vertical mounting is not permitted due to cooling and mechanical constraints.
3. What clearance does the IC695CHS016 require for installation?
You must maintain a minimum clearance of 102 mm (4 inches) on all sides of the backplane. This space enables natural air circulation and cooling.
4. Does the IC695CHS016 support hot-swapping of modules?
Yes, the backplane supports hot-swapping. You can replace or add modules while the system remains powered on, minimizing downtime.
5. What is the input voltage for the IC695CHS016 backplane?
The backplane requires an isolated +24 Volts DC input. Connect this power to Terminal 7 (positive) and Terminal 8 (ground) on the TB1 strip.
