TRICONEX DI3361 is a high-security digital input module designed for triple modular redundancy (TMR) safety control systems for emergency shutdown (ESD), process interlocking, and safety instrumentation systems (SIS) in high-risk industries such as oil, gas, and chemical. The module belongs to Triconex Tricon V11 series and conforms to IEC 61508 SIL 3 safety class. It supports fault self-diagnosis and redundancy fault tolerance to ensure reliable acquisition and processing of critical signals.

Core Functions

Multi-channel signal input

Support 24 VDC dry/wet contact input, compatible with switching signals (such as limit switches, relay contacts).

32 channels of independent isolated input, each channel equipped with dual LED status indication (operation/failure).

Triple redundancy architecture

Using TMR (Triple Modular Redundant) design, each channel is processed by three independent circuits in parallel to realize "2-out-of-3" voting logic and improve system reliability.

Real-time diagnosis and protection

Built-in broken line detection, short circuit detection and reverse polarity protection function, real-time report channel abnormal status.

Supports online health monitoring and generates diagnostic reports via the Tricon controller.

Technical parameters

Input type:

Dry contact: 0-5 VDC logic level (open/closed).

Wet contact: 15-30 VDC input with overvoltage protection (±35 VDC tolerance).

Number of channels: 32 channels (each channel independently isolated, isolation voltage ≥2500 VAC).

Response time: ≤5 ms (typical value, from signal change to system response).

Power requirements: backplane power supply (5 VDC, maximum power consumption 4 W).

Working Environment:

Temperature: -40°C to +70°C (in line with industrial wide temperature standards).

Humidity: 0%-95% non-condensate.

Protection grade: IP20 (to be installed in the control cabinet to avoid dust/water vapor intrusion).
