Introduction and technical indicators of intelligent power distribution
2012-1-6 9:59:47

I. Performance Introduction:


可为传感器等需要供电的一次仪表提供DC24V电源,并可接收一路或二路一次仪表输出的各种线性信号,在经过仪表处理后,变送输出相互隔离的 Intelligent power distributor can provide DC24V power for sensors and other primary instruments that need to be powered, and can receive one or two primary instrument output linear signals. After processed by the instrument, the transmission output is isolated from each other

Single or dual voltage or current signal up to three. Provide electrical isolation between input, output, and power.


Technical characteristics:


The intelligent power distributor adopts a highly integrated single-chip microcomputer chip, which has a high degree of integration, high accuracy, high linearity, strong anti-interference ability, and simple adjustment and verification. With traditional analog distribution and many digital distribution

Many advanced properties. The intelligent chip provides software suppression and processing for high and low frequency interference signals in the input signal. Reliable performance is maintained even in high power variable frequency control systems. The meter does not require external zero and

Full-scale potentiometer can digitize the signal automatically / manually. At the same time, the input signal can be automatically compensated.


The intelligent power distributor can also be connected with the JCBC-1001 operator through communication to observe the input and output values online. 除通用的功能外,还可支持对信号进行逻辑处理,对输入的状态设置报警 In addition to common functions, the intelligent power distribution unit can also support logic processing of signals and set alarms on the status of inputs.

The output has brought revolutionary progress to the function of the distributor and widened the scope of use of the distributor.

The powerful software functions of the intelligent power distributor and its excellent hardware and electrical performance provide a solid guarantee for the stability and reliability of the product. And make the overall performance of the product lead the international advanced level.

可与单元组合仪表及DCS、PLC等系统配套使用,可广泛应用于油田、石化、电力、制造、冶金、制药等各类复杂的工控环境。 Intelligent power distributors can be used with unit combination meters and DCS, PLC and other systems. They can be widely used in various complex industrial control environments such as oil fields, petrochemicals, power, manufacturing, metallurgy, and pharmaceuticals.
