TRICONEX 2301 Digital Output Module
Product Overview
The TRICONEX 2301 is an 8-channel digital output module designed for TRICONEX’s Tricon Triple Modular Redundancy (TMR) safety systems, a core platform in safety instrumented systems (SIS) for industrial automation. This module serves as a critical link between the Tricon controller and field actuators—such as solenoid valves, motor starters, and alarm buzzers—converting digital control signals from the controller into electrical outputs to trigger safety actions in high-risk processes.
As a key component of the Tricon TMR architecture, the TRICONEX 2301 integrates seamlessly with Tricon racks and processors like the TRICONEX 3008, ensuring redundant signal processing to eliminate single points of failure. It supports 24 V DC output signals, a standard in industrial settings, with each channel capable of handling up to 1 A of current—sufficient to drive small to medium-sized actuators used in oil refineries, chemical plants, and power stations. The module communicates with the controller via the TMR bus, ensuring real-time transmission of control commands essential for timely safety responses, such as emergency shutdowns.
Built to withstand harsh industrial environments, the TRICONEX 2301 operates in temperatures from -40°C to 70°C and humidity up to 95% (non-condensing). It features channel-to-backplane isolation (250 V AC) to resist electrical noise and ground loops, ensuring reliable operation even near large motors or high-voltage equipment. With SIL 3 certification (IEC 61508), it meets the highest safety standards, making it ideal for critical applications where failure could lead to personnel harm or environmental damage. Though a legacy model, the TRICONEX 2301 remains vital for maintaining older Tricon systems, offering compatibility with both legacy and modern actuators to avoid costly full-system upgrades.

Main features and advantages
Triple Modular Redundancy (TMR): The 2301 uses TMR technology, with three independent channels generating output signals simultaneously. If one channel fails, the other two ensure the correct signal reaches the actuator—critical for safety applications like triggering emergency shutdown valves in an oil pipeline, where a failed output could lead to spills.
8-channel control: With 8 isolated output channels, the 2301 can control 8 separate actuators—such as solenoid valves in a chemical mixing process—with a single module. This reduces hardware complexity, saving space in Tricon racks and simplifying wiring, which is valuable in compact control cabinets on offshore platforms.
24 V DC compatibility: The module outputs 24 V DC, the standard voltage for most industrial actuators. This allows direct connection to solenoid valves, motor starters, and alarms without external relays, cutting costs and reducing points of failure in the control chain.
SIL 3 certification: Certified to IEC 61508 SIL 3, the 2301 meets the highest safety standards, making it suitable for high-risk environments—such as nuclear power plants or refineries—where reliable output control is critical to preventing harm to personnel or the environment.
Rugged design: Operating in temperatures from -40°C to 70°C and resisting high humidity, the 2301 performs reliably in extreme conditions—from arctic oil fields to desert solar plants. Its 250 V AC isolation shields against electrical noise, ensuring outputs remain stable near large motors or welding equipment.
Hot-swappable capability: The module can be replaced while the system runs, allowing maintenance without shutting down critical processes. This minimizes downtime in continuous operations like natural gas processing, where unplanned stops cost thousands per hour.

Installation and maintenance
Pre-installation preparations: Verify the 2301 is compatible with your Tricon rack (e.g., Tricon 2000) and controller (e.g., 3008). Ensure the power supply provides 24 V DC ±10%. Power off the system and disconnect all power sources. Align the module with an empty I/O slot and push until it clicks into the backplane. Connect actuators to the terminal block, matching each to a channel (positive to signal terminal, negative to common terminal). Use shielded cables and ground the shield to reduce noise. Power on the system and check the module’s status LED—solid green indicates normal operation.
Maintenance suggestions: Inspect the 2301 quarterly. Wipe dust from its surface with a dry cloth to prevent overheating. Check terminal screws to ensure tight connections—loose wires can cause intermittent actuator failures (e.g., a valve failing to open). Use Tricon’s diagnostic software to monitor output status; if an actuator doesn’t respond, test the actuator first. If the actuator works, power off the system, remove the 2301, and reinsert it to fix backplane connection issues. Store a spare 2301 in a dry, cool area (10–30°C) to enable quick replacement during failures, minimizing process interruptions.
Application fields
The TRICONEX 2301 is widely used in industries requiring reliable digital output control for safety and efficiency:
- Oil and gas: In onshore refineries, the 2301 controls 8 emergency shutdown valves (ESVs) on crude oil lines. When the Tricon controller detects high pressure via input modules like the 2101, the 2301 triggers the ESVs to close, preventing pipeline ruptures.
- Chemical processing: In a pharmaceutical plant, the 2301 operates 8 purge valves in a sterile manufacturing chamber. It opens valves to flush contaminants when input sensors detect impurities, ensuring compliance with strict cleanliness standards.
- Power generation: In coal-fired plants, the module controls 8 damper actuators in a boiler’s air intake system. It adjusts dampers based on temperature data from analog modules, optimizing combustion efficiency and reducing emissions.
- Water treatment: In wastewater facilities, the 2301 activates 8 sludge pump motors. It starts pumps when float switches (monitored by input modules) detect high sludge levels, preventing overflow and maintaining treatment efficiency.
