Description
Product Description
The TRICONEX 8310 is a 32-channel triple modular redundancy (TMR) digital input (DI) module from Schneider Electric’s Triconex 8300 series, tailored for Tricon V10/V11 safety controllers in SIL 3 safety instrumented systems (SIS). It supports 24-125 VDC dry/wet contacts with 2oo3 voting for fault tolerance, and optical isolation per channel to shield against surges and noise. The TRICONEX 8310 integrates with TriStation 1131 engineering software for channel-level diagnostics (open/short circuits) and real-time monitoring, with <10ms response time for critical safety actions. Its hot-swappable design allows maintenance without system shutdown, and TÜV certification ensures compliance with IEC 61508/IEC 61511. The TRICONEX 8310 operates in -40°C to +70°C with 5g vibration resistance, ideal for harsh industrial settings. It delivers 99.99% availability via redundant voting and on-line diagnostics, minimizing unplanned downtime in ESD, BMS, and F&G systems. The TRICONEX 8310 is a cost-effective choice for safety-critical DI expansion, combining TMR reliability with seamless Tricon platform integration.

Selection Suggestions and Precautions
- Selection Suggestions
- Choose the TRICONEX 8310 for Tricon V10/V11 SIS needing 32-channel DI with 2oo3 redundancy and SIL 3 compliance.
- Pair with redundant Tricon controllers for ESD/BMS/F&G systems requiring hot-swappable maintenance.
- Prioritize for applications needing <10ms response and on-line diagnostics to enhance safety and reduce downtime.
- Precautions
- Use 24-125 VDC input to avoid damaging the TRICONEX 8310 or causing voting errors.
- Calibrate channels quarterly to maintain <10ms response and 2oo3 voting integrity.
- Follow ESD protocols during hot-swap to protect TMR circuitry and communication ports.
- For new projects, ensure compatibility with Tricon V10/V11 firmware; the TRICONEX 8310 is not compatible with Trident controllers.
