The GE IC695CHS016-CA is a 16-slot universal backplane  from the PACSystem RX3i series, originally manufactured by GE Intelligent Platforms (now part of Emerson Automation ). It’s designed to host a variety of controller and I/O modules, supporting both the newer RX3i series and the legacy Series 90-30 modules .

Here are its detailed technical specifications:

⚙️ 1. General Specifications

• Model: IC695CHS016-CA
• Type: Universal Backplane (also referred to as a chassis or rack)
• Slot Configuration: 16 slots
  • Slot 0: Reserved for a power supply module (IC695 type) .
  • Slots 1-5: Dual-connector slots supporting both PCI-based (for RX3i modules like IC695) and serial-based (for Series 90-30 modules like IC693/IC694) connections .
  • Slots 6-15: PCI-only slots, compatible only with RX3i modules .
• Compatibility: Supports RX3i PACSystem modules (IC695 series) and Series 90-30 I/O and option modules (IC693, IC694 series) .

? 2. Electrical Characteristics

• Input Voltage: +24 VDC (isolated)
• Internal Power Consumption:
  • 5 VDC: 240 mA
  • 3.3 VDC: 600 mA
• Backplane Current Consumption: 80 mA @ 5VDC and 125 mA @ 24VDC
• Isolation: Features isolated 24 VDC terminal block (TB1, Terminal 7) and isolated ground (Terminal 8) .

? 3. Physical Dimensions & Mechanical Design

• Dimensions (H x W x D): 141.4 mm x 602 mm x 147.3 mm (5.57 in x 23.7 in x 5.8 in)
• Installation:
  • Orientation: Horizontal mounting only . Other orientations may affect airflow and system performance .
  • Enclosure Requirement: Requires a protective enclosure rated at least NEMA/UL Type 1 (IP20 per IEC 60529) . For hazardous locations (Class I, Division 2, Groups A, B, C, D), a higher protection rating of IP54 or greater is needed .
  • Clearance: Minimum clearance of 102 mm (4 inches) on all sides is required for adequate natural air cooling .
• Features: Includes an integrated grounding bar for module shields and ground connections, and clear slot numbering . A terminal block for isolated 24VDC input is located at the left end .

? 4. Functional Features

• Bus Support: Dual bus architecture:
  • High-speed PCI bus (27 MHz) for enhanced data transfer with complex I/O applications .
  • Serial bus for optimized performance with simpler I/O applications .
• Hot-Swap Support: Allows for module hot-swapping, which can reduce system downtime during maintenance .
• Expansion Capability: Provides interfaces for local expansion rack interconnection, allowing connection to additional modules on the same bus .

? 5. Standards & Certifications

• Safety Standards: UL 508
• Equivalent Standards: CSA C22.2 No. 142
• Hazardous Locations Certification: Class I, Division 2, Groups A, B, C, D .

?️ 6. Typical Applications

This universal backplane is a core component in industrial automation systems, used to build and expand PACSystem RX3i controllers. Its applications span across:

• Manufacturing: Automotive assembly lines, robotic control .
• Energy: Power generation monitoring and control (e.g., wind turbine control ), substation automation .
• Oil & Gas: Monitoring and controlling process parameters like temperature and pressure .
• Water Treatment: Controlling pumps, valves, and filtration systems .
• Infrastructure: Transportation systems .
