After processing by the instrument, the transmission output is isolated from the single and double channels. Three voltage or current signals. Provide electrical isolation between input, output, and power.
采用高度集成的单片机芯片，集成化程度高、精度高、线性度高、抗干扰能力强，调整及校验简单。 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. It has many advanced features that traditional analog power distributors and many digital power distributors do not have. 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 can digitize signals automatically / manually without external zero and full-scale potentiometers. 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. In addition to the general functions, the intelligent power distributor can also support the logical processing of signals and the setting of alarm output on the state of the input, which has brought revolutionary progress to the function of the power distributor and broadened the scope of use of the power 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. The energy distribution device can be used with unit combination meters and DCS, PLC and other systems. It can be widely used in various complex industrial control environments such as oil fields, petrochemicals, power, manufacturing, metallurgy, and pharmaceuticals.
