Description
Triconex MA2211-100
(8-Channel Analog Input Module for Safety Instrumented Systems)
Product Overview
The Triconex MA2211-100 is an 8-channel analog input module designed for Tricon CX and Trident safety systems by Schneider Electric. This module converts analog signals (e.g., 4–20 mA, 0–10 VDC) from field sensors into digital data for processing by Triconex controllers, enabling critical safety functions in oil and gas, chemical, and power generation industries. Compliant with IEC 61508 SIL 3 standards, it ensures reliable monitoring of process variables like pressure, temperature, and flow in safety instrumented systems (SIS).
Key Features
- High Availability: Dual redundant circuitry and fault-tolerant design for continuous operation.
- Input Types: Configurable for 4–20 mA, 0–10 VDC, or RTD/TC signals (varies by firmware).
- Diagnostics: Continuous self-testing for open circuits, short circuits, and signal drift.
- Integration: Compatible with Tricon v11/v12 and Trident safety systems via TriBus communication.
- Certifications: SIL 3 (TÜV), ATEX/IECEx (with appropriate barriers).
