TRICONEX DI3361 Digital Input Module

The TRICONEX DI3361 serves as a critical component in safety instrumented systems, providing high-reliability digital input acquisition for industrial automation. This module excels in environments requiring precise monitoring of discrete signals, such as emergency shutdown systems in oil & gas facilities or turbine control in power plants. Its triple-redundant architecture ensures fault-tolerant operation, making it ideal for SIL 3 applications.

Brand: TRICONEX Model: DI3361 Operating Voltage: 24 VDC Input Channels: 16 isolated inputs Signal Type: Dry contact/24V DC Isolation Voltage: 1500 VAC Communication: TriBus protocol Certifications: IEC 61508, FM, ATEX

In practice, this module has become a workhorse for critical control applications across multiple sectors. A chemical plant in Texas recently upgraded their reactor monitoring system using DI3361 modules, achieving 99.999% uptime over 18 months. The reinforced isolation design proved particularly valuable in their electrically noisy environment. We commonly pair this module with TRICONEX 3009X power supplies and 3721 communication interfaces for complete system solutions.
