TRICONEX 3806E Analog Output Module

TRICONEX 3806E Analog output module

Functional characteristics

Multi-channel analog output: Usually equipped with multiple output channels (commonly 8 channels), it can simultaneously output multiple analog signals and independently control multiple field devices, such as control valves and frequency converters, meeting the requirements of complex industrial control systems for multi-parameter regulation.

High-precision output: It features A high resolution (typically 16 bits or higher), capable of achieving high-precision D/A conversion, outputting stable and accurate analog signals, accurately conveying the instructions of the control system to on-site equipment, ensuring precise control of industrial processes, and reducing control deviations.

Three-mode Redundancy (TMR) design: It adopts a three-mode redundancy architecture, with three independent circuit channels inside the module for parallel processing and voting of the output signal. This design significantly enhances the reliability and fault tolerance of the module. Even if one of the channels fails, the module can still output the correct analog signal to maintain the stable operation of the system and meet high-level safety and integrity requirements such as SIL3. It is suitable for industrial scenarios with extremely high safety requirements.

Real-time fault diagnosis and feedback: It features a powerful self-diagnosis function that can monitor the module's own working status in real time, including power faults, channel faults, output abnormalities, etc. Once a fault is detected, it can promptly issue an alarm signal and visually display the fault information through indicator lights and other means. At the same time, it feeds back the fault information to the control system, facilitating maintenance personnel to quickly locate and eliminate the fault and reducing the risk of system downtime.

Wide range output and compatibility: It can output various types and ranges of analog signals, such as 4-20mA current signals and 0-10V voltage signals, etc. It is compatible with all kinds of industrial field equipment without the need for complex signal conversion and adaptation circuits.

Electrical isolation: It has excellent electrical isolation performance between channels and between modules and other parts of the system, effectively suppressing electromagnetic interference and common-mode interference, improving the stability and accuracy of signal output, and ensuring reliable transmission of control signals to on-site equipment even in complex electromagnetic environments.

Technical parameters

Output channel quantity: Generally 8 channels, which can be independently configured and used.

Output signal type: Supports 4-20mA, 0-20mA current output, as well as 0-5V, 1-5V, 0-10V, ±10V and other voltage output signals.

Resolution: Usually 16 bits, it can provide fine output control and meet the high-precision control requirements of industrial sites.

Output accuracy: Within a certain temperature range (such as 0-60 ℃), the output accuracy can reach ± 0.1%FS (full scale) or higher, ensuring the accuracy of the output signal.

Output load capacity: It has a strong load-carrying capacity. For instance, when outputting current, the load resistance can generally be within a certain range (such as 0-600 Ω). When outputting voltage, there are also corresponding load requirements to ensure the stability of the signal output.

Working voltage: Mostly 24VDC DC power supply is adopted, allowing a certain voltage fluctuation range (such as ±15%) to adapt to the complex and changeable power supply environment in industrial sites.

Isolation voltage: The isolation voltage between channels and between the module and the backplane is relatively high. For instance, the isolation voltage between channels can reach 500VDC, and the isolation voltage between the module and the backplane can reach 2500VDC, effectively ensuring electrical safety and signal quality.

Application scenarios

Petrochemical industry: It is used to precisely control parameters such as the feed flow rate of the distillation column, the opening degree of the pressure regulating valve at the top of the column, as well as the temperature and stirring speed of the reaction vessel, ensuring the stable and efficient operation of the production process and avoiding product quality issues or safety accidents caused by inaccurate control.

In the power industry, in power plants, the speed regulation system of steam turbines, the excitation regulation of generators, and the adjustment of the tap positions of transformers in substations are controlled to maintain the voltage and frequency stability of the power system and ensure reliable power supply.

Pharmaceutical and food industries: During the production process, precisely control parameters such as the temperature of the reaction vessel, the amount of material added, and the filling liquid level to meet strict production process requirements, ensure the consistency and stability of product quality, and comply with the production norms and standards of relevant industries.

In the sewage treatment industry: Control the rotational speed of aeration fans and the flow rate of dosing pumps in sewage treatment equipment, optimize the sewage treatment process, improve the efficiency and quality of sewage treatment, and ensure that sewage is discharged up to standard.
