Product Overview
The TRICONEX 3564 is a high-performance digital input module designed for safety instrumented systems (SIS) and critical industrial automation environments. As a key component of TRICONEX’s Tricon and Trident platforms, it specializes in receiving and processing discrete digital signals from field devices such as switches, sensors, and relays, converting them into actionable data for safety controllers. This role makes the TRICONEX 3564 essential for maintaining operational safety in settings where even minor signal errors could lead to catastrophic incidents.
Built on TRICONEX’s triple modular redundancy (TMR) architecture, the TRICONEX 3564 features three independent processing channels that operate in parallel. If one channel fails, the other two continue functioning, ensuring uninterrupted operation and meeting SIL 3 safety standards (IEC 61508). It supports 32 isolated digital input channels, each with 2.5 kV galvanic isolation to protect against voltage spikes, ground loops, and electromagnetic interference—common challenges in industrial settings like refineries and power plants.
The TRICONEX 3564 integrates seamlessly with TRICONEX’s TriStation configuration software, allowing users to configure input thresholds, filtering, and diagnostic parameters to match specific application needs. Its rugged construction enables operation in extreme temperatures (-40°C to 70°C) and high-humidity environments, making it suitable for offshore platforms, chemical plants, and nuclear facilities. Whether monitoring emergency stop signals or pressure switch statuses, the TRICONEX 3564 delivers real-time data with precision, reinforcing its role as a cornerstone of modern safety-critical systems.

Main features and advantages
Triple modular redundancy for uncompromising reliability: The TRICONEX 3564 uses three independent processing channels to process signals simultaneously. This TMR architecture ensures that even if one channel fails, the module continues operating without interruption, meeting SIL 3 safety standards. This reliability is critical in applications like emergency shutdown systems (ESD) in oil refineries, where downtime could lead to environmental disasters or equipment damage.
High channel density with robust isolation: The TRICONEX 3564 supports 32 isolated digital input channels, each protected by 2.5 kV galvanic isolation. This isolation prevents voltage spikes, ground loops, and electromagnetic interference from disrupting signals, ensuring accurate transmission of critical data such as emergency stop commands or pressure switch alerts. The high channel density reduces the need for multiple modules, saving space in control cabinets and simplifying system design.
Rugged design for harsh industrial environments: Built to withstand extreme temperatures (-40°C to 70°C) and high humidity, the TRICONEX 3564 performs reliably in harsh settings like Arctic pipelines, chemical reactors, and offshore platforms. Its ATEX/IECEx certification further allows use in explosive atmospheres, ensuring compliance with strict safety regulations and reducing the risk of operational failures in hazardous areas.
Seamless integration and easy configuration: The TRICONEX 3564 works seamlessly with TRICONEX’s TriStation configuration software, enabling users to set input thresholds, filtering, and diagnostic parameters to match specific application needs. It supports standard industrial protocols like Modbus RTU, ensuring compatibility with third-party controllers and legacy systems. This flexibility simplifies both new installations and system upgrades, reducing deployment time and costs.
Advanced diagnostics for proactive maintenance: The TRICONEX 3564 includes built-in diagnostics that continuously monitor channel health, detecting faults such as open circuits, short circuits, or signal degradation. Faults are isolated and flagged in real time, allowing maintenance teams to address issues before they escalate. This reduces mean time to repair (MTTR) and enhances overall system availability, ensuring that critical processes remain operational.

Installation and maintenance
Pre-installation preparations: Before installing the TRICONEX 3564, power off the target system to avoid electrical damage. Verify that the system firmware is compatible with the module—outdated firmware may cause communication issues or limit functionality. Inspect the TRICONEX 3564 for physical defects, such as bent pins, cracked casings, or damaged terminals, which could impair performance. Ensure the mounting area (DIN rail or rack) is clean, level, and securely fastened to resist vibration, which can loosen connections over time. Confirm that the 24 V DC power supply meets the module’s current requirements (0.5 A max) to prevent overloading and ensure stable operation.
Maintenance suggestions: Regular maintenance is essential to keep the TRICONEX 3564 operating reliably. Conduct quarterly visual inspections to check for loose terminal connections, dust accumulation, or corrosion on the module’s surfaces. Clean the module with compressed air to remove dust from vents, as buildup can cause overheating. Test signal transmission quarterly by sending test signals from connected devices and verifying that the TRICONEX 3564 transmits them accurately to the controller. Update the module’s firmware annually using TriStation software to address bugs and improve compatibility with system upgrades. If faults are detected, use the module’s LED indicators to identify issues; replace the TRICONEX 3564 if necessary, leveraging its hot-swap capability to minimize downtime.
Application fields
The TRICONEX 3564 is widely used in industries where safety and reliability are critical. In the oil and gas sector, it monitors signals from pressure switches, flow meters, and emergency shutdown buttons in drilling rigs and pipelines. For example, if a pipeline pressure sensor detects a dangerous spike, the TRICONEX 3564 processes this signal and sends it to the SIS, which triggers an emergency shutdown to prevent leaks, explosions, or environmental damage.
In chemical processing plants, the TRICONEX 3564 is part of fire and gas detection systems, receiving signals from gas detectors, heat sensors, and flame detectors. It ensures these signals are transmitted accurately to the SIS, which activates suppression systems, vent valves, or isolation barriers to contain hazards, protecting workers and preventing the release of toxic chemicals.
In power generation facilities—including fossil fuel, nuclear, and renewable plants—the TRICONEX 3564 monitors turbine vibration, boiler pressure, and generator temperature sensors. It ensures that critical status signals are transmitted to the SIS, which can shut down equipment if readings exceed safe limits, preventing costly damage or power outages that could disrupt energy supplies.
In pharmaceutical manufacturing, the TRICONEX 3564 monitors cleanroom sensors, such as air pressure monitors, door interlocks, and sterilization equipment statuses. It ensures that deviations from sterile conditions are quickly detected and addressed, helping facilities comply with Good Manufacturing Practices (GMP) and regulatory standards, and preventing contamination of sensitive products.
