TRICONEX 3009 high-density digital input module

The TRICONEX 3009 is a high-density digital input module designed for the TRICONEX Tricon Safety Instrumented System (SIS) — a core product line of Schneider Electric (acquired TRICONEX) specialized in critical industrial safety and control. As a key component of the Tricon SIS, the 3009 module is engineered to reliably acquire digital signals from field devices (e.g., limit switches, pressure switches, emergency stop buttons) in harsh industrial environments. It integrates triple-modular redundancy (TMR) technology — the hallmark of TRICONEX systems — to ensure fault tolerance, making it suitable for safety-critical applications where downtime or false trips could lead to catastrophic consequences (e.g., process leaks, equipment damage, or personnel harm). Below is its comprehensive detailed information:

I. Core Technical Parameters

Category	Specific Specifications
Basic Identification	- Model: TRICONEX 3009- Product Type: High-Density Digital Input Module (TMR Architecture)- Applicable System: TRICONEX Tricon SIS (compatible with Tricon V9, V10, V11, and newer firmware versions)- Core Role: Redundant acquisition of 24V DC digital input signals from field devices; provides fault-tolerant signal processing for safety-critical logic (e.g., emergency shutdown, process interlock)
Input Configuration	- Channel Quantity: 32 independent digital input channels (divided into 4 groups of 8 channels; each group supports separate isolation and diagnostics)- Input Signal Type: Dry contact (NO/NC) or wet contact (24V DC active-high/active-low, software-configurable)- Input Voltage Range: 18V DC ~ 32V DC (compatible with standard industrial 24V DC power supplies)- Input Current: 5mA ~ 10mA per channel (typical, at 24V DC; low power consumption to reduce heat buildup)- Input Response Time: <10ms (from signal detection to data transmission to the Tricon controller; critical for fast safety interlocks)
Redundancy & Fault Tolerance	- Architecture: Triple-Modular Redundancy (TMR) — each input channel is processed by three independent electronic paths (sensors, signal conditioning, logic circuits). The system uses "2-out-of-3 (2oo3) voting" to validate signals: a valid input is confirmed only if at least 2 of the 3 paths detect the same state (prevents false trips from single-component failures).- Channel Isolation: Galvanic isolation between channel groups (500V AC RMS, 1 minute) and between inputs and backplane (1500V AC RMS, 1 minute); eliminates cross-talk from ground loops or electrical noise.- Self-Diagnostics: Continuous monitoring of internal components (e.g., power regulators, input buffers, isolation circuits). Detects faults such as open circuits, short circuits, or component degradation, and reports them to the Tricon controller via the backplane.

The company has multiple main brands, and if you have other brand requirements, you can also send them to customer service for inquiry.
