The Triconex 3301 digital input module is a key component in the Triconex family of control systems for receiving and processing digital input signals from external devices. Here are the details:

Functional characteristics

Digital signal reception: can receive discrete digital signals from switches, relays, sensors and other field equipment, used to monitor the operating status of equipment, alarm signals, such as the reception of button press or release signal, relay contact closure or disconnection signal.

High reliability design: Redundant design compatible with the Triconex system's Triple redundancy (TMR) architecture. The system works even if some modules fail, ensuring high reliability in mission-critical applications.

Excellent safety performance: in line with SIL3 safety standards, with high safety, can be used in petroleum, chemical, aerospace and other industrial control occasions with high safety requirements.

Electrical isolation protection: Provides electrical isolation between the input channel and the module, which can effectively prevent the impact of external electrical interference and potential faults on the system, and enhance the stability and anti-interference ability of the system.

Fast response ability: With fast signal acquisition and processing ability, it can respond to the status change of the field equipment in real time, which is suitable for real-time control applications with high response time requirements.

Hot swap function: Supports hot swap, and can easily expand, maintain, and replace modules without downtime during system operation, thus reducing system downtime and improving production efficiency.

Technical specification

Number of input channels: Typically up to 32 digital input channels are supported to connect multiple field devices at the same time to meet the control needs of different scales.

Input signal type: can handle dry contact, DC voltage level (usually 24V DC) and other standard digital signals, can adapt to a variety of field equipment output signal types.

Input voltage range: accepts a wide input voltage range, generally 15-30V DC, with strong voltage adaptability, can adapt to the fluctuations of different on-site power supplies.

Response time: The response speed is fast, and the change of the input signal can be transmitted to the control system in a short time to meet the requirements of real-time control.

Operating temperature range: can work stably in a certain temperature range, generally 0℃ -60 ℃, to adapt to a variety of industrial environment temperature conditions.

Installation method: Usually using DIN rail installation or installation in the control cabinet, convenient and fast, easy to maintain and manage.

Triconex is both the name of a Schneider Electric brand that supplies products, systems and services for safety, critical control and turbomachinery applications and the name of its hardware devices that utilize its TriStation application software. Triconex products are based on patented Triple modular redundancy (TMR) industrial safety-shutdown technology. Today, Triconex TMR products operate globally in more than 11,500 installations, making Triconex the largest TMR supplier in the world.

Company History: The history of Triconex was published in a book called ‘The History of a Safer World’ by Gary L. Wilkinson. The company was founded in September, 1983 by Jon Wimer in Santa Ana, California and began operations in March, 1984. The business plan was written by Wimer and Peter Pitsker, an automation industry veteran and Stanford graduate. They presented the plan for a TMR (Triple Modular Redundant) based system that would improve the safety and reliability in industrial applications. Among the customers they targeted were the petro-chemical giants, such as Exxon, Shell, Chevron, and BP.

Pitsker and Wimer presented the business plan to Los Angeles based investor Chuck Cole, who was also a professor at USC. Cole was interested, so he contacted his personal attorney, future two-time Los Angeles Mayor Richard Riordan. Riordan agreed to invest $50,000 and Cole’s venture capital team matched it, providing the seed money for Triconex. After two years, however, the company nearly failed due to the expense and complications of testing a new safety system. In February, 1986, founder Wimer left the company and the board asked a seasoned executive, William K. Barkovitz to become CEO. Barkovitz ended up leading the company for 9 years. At the end of his term, Triconex became the leading safety system in a market it largely created, made acquistitions, and completed an IPO. In January, 1994, Triconex was acquired by British based SIEBE for 90 million dollars.

The Triconex system usually consists of the following typical modules:

Main Processor modules (triple).

Communication module(s) .

Input and output modules: can be analog and/or digital and work singular or in hot-spare (standby).

Power supply modules (redundant).

Backplane(s) (chassis) that can hold the previous modules.

System cabinet(s): can compact one or more chassis in one cabinet.

Marshalling cabinets to adapt and standardize interface connections between the field instruments and the Triconex system cabinets.

Human machine interface (HMI) to monitor the events.

Engineering workstation (EWS) for programming. monitoring, troubleshooting and updating.

The Triconex main processors can communicate with the so-called TriStation 1131 application software to download, update and/or monitor programs. These programs are either written in:

Function Block Diagram language,

Ladder diagram language, or

Structured text (Pascal like) Language.

Cause and Effect Matrix Programmable Language (CEMPLE).

Besides, a Sequence of Events (SOE) recorder software and Diagnostic monitor software are implemented.
