TRICONEX 3720 Module

Category	Specific Content
Product Name	TRICONEX 3720 Analog Output Module (Tricon Safety Instrumented System)
Product Description	The TRICONEX 3720 is a high-reliability analog output module designed for the TRICONEX Tricon safety instrumented system (SIS), developed by Schneider Electric’s Triconex brand (formerly Invensys). It is engineered specifically for critical industrial applications requiring SIL 3 (Safety Integrity Level 3) certification, such as petrochemical refineries, offshore platforms, power generation plants, and pharmaceutical production lines. As a core component of the Tricon fault-tolerant control system, the module adopts a triple-modular redundant (TMR) architecture, which ensures continuous operation even if one or two of its internal channels fail. It converts digital control signals from the Tricon controller into precise analog outputs (current or voltage) to drive field actuators like control valves, variable frequency drives, and positioners. The module features built-in self-diagnostic functions, real-time fault monitoring, and hot-swappable capability, minimizing system downtime and ensuring the safety and availability of mission-critical processes. It seamlessly integrates with Tricon’s engineering and diagnostic tools, enabling easy configuration, calibration, and troubleshooting for maintenance personnel.
Product Parameters	1. Output Channel Parameters: Configured with 4 independent analog output channels; supports two output types per channel: 4–20mA DC current (default) and 0–10V DC voltage (selectable via configuration). Each channel provides isolated signal output to prevent cross-channel interference. 2. Accuracy & Resolution Parameters: Current output accuracy is ±0.1% of full scale (FS); voltage output accuracy is ±0.2% of FS; output resolution is 16 bits for both current and voltage signals, ensuring high-precision control of field devices. 3. Power Supply Parameters: Operates on 24V DC redundant power input from the Tricon chassis backplane; voltage fluctuation tolerance is ±10% (21.6V DC–26.4V DC); typical power consumption per module is ≤ 15W, with no additional power required for field-side signaling. 4. Environmental & Reliability Parameters: Operating temperature range is -40°C to 70°C; storage temperature range is -40°C to 85°C; adaptable to humidity of 5%–95% RH (non-condensing); complies with IEC 61000-4-2/3/4/5 for EMC protection against electrostatic discharge, radio frequency interference, and electrical surges; certified to IEC 61508 (SIL 3) and TÜV Rheinland safety standards for critical SIS applications.
