Product Description
The Triconex 3700E is a high-precision analog input module designed for integration into the Tricon safety instrumented system (SIS). This module captures reliable analog signals from field devices, including sensors, transmitters, and controllers, and delivers them to the Tricon controller for processing in critical industrial environments.
Engineered for applications where safety and continuous operation are essential, the 3700E uses Triple Modular Redundancy (TMR) architecture to maintain operation even if one channel fails. With 32 isolated analog input channels, this module supports 4–20 mA signals with 12-bit resolution, ensuring accurate and dependable signal conversion.
Diagnostics continuously monitor signal integrity and wiring faults, detecting open or short circuits to maintain system safety. The module is hot-swappable, enabling replacement or maintenance without interrupting system operation. With compliance to IEC 61508, ANSI/ISA, CE, UL, ATEX, and IECEx standards, the 3700E is ideal for SIS deployments in oil & gas, chemical, petrochemical, and power generation facilities. It supports standard industrial communication protocols, including Modbus, Profibus, HART, and Foundation Fieldbus, for seamless integration into complex process control systems.
