TRICONEX 3674 Dual Digital Output Module
TRICONEX 3674 Dual Digital Output Module
Overview
The TRICONEX 3674 is a 32‑point dual digital output (DDO) module for Triconex TMR Safety Instrumented Systems (SIS) (Schneider Electric). It provides 24 VDC outputs with dual‑redundant circuitry and self‑protected channels, delivering cost‑effective fault tolerance for safety‑critical applications that do not require full TMR output redundancy.
Key Features
- Dual Redundancy Architecture: Two independent output circuits per point; 2oo3 voting on commands from three main processors, ensuring no spurious outputs from single faults.
- 32‑Point 24 VDC Output: 24 VDC nominal (20–30 VDC), 2A max per channel, 10A surge (10 ms) for inductive loads (valves, relays, solenoids).
- Self‑Protected Outputs: Internal overcurrent protection per channel; no external fuses required, simplifying wiring and reducing failure points.
- Comprehensive Diagnostics: Voltage‑loopback circuit verifies output switch operation (no load required); monitors open/short circuits, voltage mismatch, and fuse faults; SOE recording ≤40 ms resolution.
- SIL 3 Safety Certified: Compliant with IEC 61508 SIL 3, TÜV, FM, and CE; suitable for ESD, F&G, and safety interlock loops.
- Hot‑Swappable: Tool‑free installation/replacement; no system downtime during maintenance.
- Harsh Environment: Operates from ‑40°C to +70°C; 1500 VDC galvanic isolation (point‑to‑backplane); vibration/shock resistant (5g vibration, 10g shock).
