The TRICONEX 3625 analog output module is a high-performance card designed specifically for the fields of industrial automation and process control. It has high precision, high reliability, and powerful functional characteristics, and is widely used in key industrial scenarios such as petroleum, chemical, and power.

1、 Core functional characteristics

High precision analog signal processing

Adopting advanced analog signal acquisition and conversion technology, supporting multi-channel input and output, capable of processing multiple analog signals simultaneously, meeting complex industrial control requirements.

Typical applications include real-time monitoring and control of physical quantities such as temperature, pressure, and flow rate.

The third mock examination Redundancy (TMR) Architecture

The module is equipped with three independent sub circuits that execute independent control logic. Through a voting mechanism, it ensures that a single point of failure will not affect system operation, greatly improving the system's fault tolerance.

Support online diagnosis and repair, enabling fault isolation and module replacement without interrupting the control process.

Multi channel output capability

Provide 32 digital output points (DO), support 24VDC voltage range, typical voltage drops below 2.8VDC, and load capacity up to 1.7A (surge).

The output channel has point level isolation (1500VDC) to effectively prevent external interference.

Communication and compatibility

Supports industrial communication protocols such as Modbus and TCP/IP, and can be seamlessly integrated into existing control networks.

Compatible with TRICONEX series controllers and other mainstream DCS (distributed control systems) such as Foxboro, Honeywell, etc.

Environmental adaptability and protection

The working temperature range is -40 ° C to 85 ° C, the relative humidity is 5% to 95% (no condensation), and the protection level is IP20.

The power module is equipped with undervoltage and overvoltage protection to ensure stable operation of the system in harsh industrial environments.

2、 Application advantages

Reliability assurance for critical task scenarios

In high-risk industries such as oil and gas, chemical, etc., TMR architecture can avoid production interruptions caused by single point failures and reduce safety risks.

For example, in the temperature control of a refinery reactor, the module can output accurate analog signals in real time to ensure stable process parameters.

Flexible Expansion of Complex Industrial Systems

Supports up to 118 I/O modules (analog and digital) and optional communication modules, expandable to remote I/O sites up to 12 kilometers away from the host.

Modular design facilitates flexible configuration according to project requirements and reduces system integration costs.

Efficient maintenance and low operating costs

Provide comprehensive online diagnostic functions, support hot plugging and online configuration, and reduce downtime.

Low power design (typical value of 3 watts) helps reduce system energy consumption and is in line with the trend of green industry.

3、 Typical application scenarios

Oil and gas: pressure control of oil and gas pipelines, monitoring of wellhead equipment.

Chemical industry: temperature regulation of reaction vessels, fluid flow control.

Electricity: excitation control of generator sets, grid monitoring.
