Product Details

◆ Overview

The intelligent power distributor provides a power circuit for primary instruments such as sensors that require power supply, and can measure various output signals of the primary instruments on the same line. After being processed by the instruments, it outputs isolated single, double, triple, and up to four linear current or voltage signals. Provide electrical isolation between input, output, and power supply.

◆ Characteristics

Provided hardware and software suppression and processing for high and low frequency interference signals in the input signal.

Can maintain reliable performance in high-power variable frequency control systems.

Without the need for external zero and full potentiometer, the signal can be digitally/automatically/manually calibrated. Simultaneously perform automatic compensation on the input signal.

By connecting with communication and intelligent operators, input and output values can be observed online.

It can be used in conjunction with unit combination instruments, DCS, PLC and other systems, and can be widely applied in various complex industrial control environments such as oil fields, petrochemicals, power, manufacturing, metallurgy, etc.

◆ Panel display

Five core communication interface

Used for communication connection between dedicated data cables and intelligent operators

PowerPower status indicator light (continuously on when powered on)

Communication status indicator light (communication flashing)

Fault status indicator light (flashing fault)

ALM1When the first alarm is triggered and the alarm conditions are met, the indicator light will remain on for a long time

ALM2When the second alarm is triggered and the alarm conditions are met, the indicator light will remain on for a long time

When the input and output signals are in a fault state, the indicator light flashes.
