TRICONEX 3000678-100 Termination Board Module
Product Overview
The TRICONEX 3000678-100 is a termination board module designed for TRICONEX’s Tricon Triple Modular Redundancy (TMR) safety systems, a critical platform in industrial safety instrumented systems (SIS). This module serves as a physical and electrical interface between field devices—such as sensors, transmitters, and actuators—and Tricon I/O modules, providing secure signal termination, isolation, and conditioning for reliable data flow in safety-critical processes.
As a key component of the Tricon TMR architecture, the TRICONEX 3000678-100 integrates seamlessly with Tricon racks and processors like the TRICONEX 3008, ensuring redundant signal paths to eliminate single points of failure. It is engineered to handle both analog and digital signals, supporting 24 V DC power and featuring channel-to-channel isolation to resist electrical noise and ground loops—essential for stable operation near large motors or high-voltage equipment in industrial settings.
Built to withstand harsh environments, the TRICONEX 3000678-100 operates in temperatures from -40°C to 70°C and humidity up to 95% (non-condensing). Its design aligns with SIL 3 certification (IEC 61508), making it suitable for high-risk applications where failure could lead to personnel harm or environmental damage. Though a legacy model, the TRICONEX 3000678-100 remains vital for maintaining older Tricon systems, offering compatibility with both legacy and modern field devices to avoid costly full-system upgrades.

Main features and advantages
Triple Modular Redundancy (TMR) compatibility: The 3000678-100 is designed to work with Tricon’s TMR architecture, where three independent signal paths ensure that even if one path fails, the other two maintain reliable signal transmission. This redundancy is critical for safety systems in oil refineries, where a break in signal could delay an emergency shutdown during a leak.
Secure signal termination: The module provides dedicated terminals for field devices, organizing wiring and reducing the risk of loose connections. Each terminal is designed to handle 24 V DC signals, the standard for industrial sensors and actuators, making it easy to connect devices without additional adapters.
Effective isolation: Channel-to-channel isolation (250 V AC) protects against electrical noise and ground loops, ensuring that signals from one field device do not interfere with others. This is especially important in factories with large motors or welding equipment, where electrical interference could distort sensor data.
Rugged design: The 3000678-100 operates in temperatures from -40°C to 70°C and resists high humidity, making it suitable for extreme environments—from arctic oil fields to desert power plants. Its durable construction ensures long service life, reducing the need for frequent replacements.
SIL 3 certification: Certified to IEC 61508 SIL 3, the module meets the highest safety standards, making it suitable for high-risk applications such as chemical reactor control, where reliable signal termination is critical to preventing accidents.

Installation and maintenance
Pre-installation preparations: Check that the 3000678-100 is compatible with your Tricon rack (e.g., Tricon 2000) and I/O modules (e.g., 2101, 2301). Ensure the power supply provides 24 V DC ±10%. Power off the system and disconnect all power sources. Mount the module on the Tricon rack, aligning it with the mounting holes and securing it with screws. Connect field device wires to the terminal block, matching each wire to the correct terminal as per the wiring diagram. Ground the module using the dedicated grounding terminal to reduce electrical noise.
Maintenance suggestions: Inspect the 3000678-100 monthly. Use a dry cloth to wipe dust from the terminals and surface to prevent overheating. Check that all wires are tightly connected—loose wires can cause intermittent signal loss, such as a sensor failing to send a “high pressure” alert. If a terminal shows signs of corrosion, clean it with a soft brush. Store a spare 3000678-100 in a dry, cool area (10–30°C) to replace quickly if the module fails, minimizing downtime in critical processes.
Application fields
The TRICONEX 3000678-100 is widely used in industries where secure signal management is key to safety and efficiency:
- Oil and gas: In offshore platforms, the module terminates signals from 16 pressure sensors in a pipeline system. It routes these signals to the Tricon controller via the 3008 module, ensuring that any pressure spike triggers an immediate shutdown via output modules like the 2301.
- Chemical processing: In a fertilizer plant, the 3000678-100 manages connections for 12 temperature sensors in a reaction vessel. Its isolation features prevent electrical noise from nearby pumps from distorting temperature readings, ensuring the controller maintains safe operating conditions.
- Power generation: In coal-fired plants, the module terminates signals from 10 flow meters in a boiler’s water supply system. It ensures that flow data reaches the controller accurately, allowing timely adjustments to prevent overheating or water shortages.
- Water treatment: In wastewater facilities, the 3000678-100 organizes connections for 8 level sensors in filtration tanks. Its rugged design resists humidity, ensuring reliable signal transmission even in damp environments, helping the controller maintain optimal water levels.
