Honeywell 10315/1/1 Redundant I/O Backplane

Honeywell 10315/1/1 Redundant I/O Backplane

The Honeywell 10315/1/1, also cataloged as the 10315 redundant I/O backplane, serves as a base board PCB for housing and interconnecting redundant I/O modules within Honeywell rack-mounted control systems.

Hardware Specifications

Channel-to-Channel Isolation and Bus Integrity

The 10315/1/1 backplane enforces channel-to-channel isolation across all I/O slots, preventing electrical interference between modules. Dedicated bus driver slots (20 and 21) maintain deterministic communication across the horizontal bus. EMI shielding via chrome-plated steel chassis ensures stable operation in industrial environments, reducing susceptibility to noise coupling.

Frequently Asked Questions (FAQ)

Q: How many I/O modules can be installed in the 10315/1/1 backplane? A: Up to 18 modules can be installed across slots 1–18.

Q: What is the maximum current supported per connector pin? A: Each I/O connector pin supports up to 2 A, while Faston pins support up to 10 A.

Q: Does the backplane consume power itself? A: No. It is a passive PCB; power is distributed via the integrated busbar.

Field Installation Guidelines

• Mount securely in a 19-inch rack with 3U clearance.
• Ensure grounding continuity between chassis and cabinet earth bus.
• Route signal wiring separately from high-voltage conductors to minimize EMI.
• Verify bus driver modules are installed in slots 20 and 21 before energizing.
• Inspect connector seating and shielding integrity prior to commissioning.
