Performance Characteristics

Input channels and signal types: Usually there are several analogue input channels, which can accept a variety of standard analogue signals such as 0-10V, 0/4-20mA and so on, and can meet the signal input requirements of different sensors.

Accuracy and resolution: the use of high-precision A/D converters, high resolution, measurement accuracy of ± 0.1% to ± 0.5% between the analogue signal can be accurately converted to digital signals to ensure accurate measurement and monitoring of analogue quantities.

Isolation and anti-interference: the input channels are isolated from each other, the isolation voltage is generally up to several hundred volts, which can effectively prevent signal interference between the channels and common mode interference, to protect the stability and reliability of the system, and can work stably in the harsh industrial environment.

Sampling Frequency: With high sampling frequency, the analogue signals of multiple channels can be sampled quickly in a short time, and the changes of analogue signals can be captured in time to meet the needs of dynamic monitoring and control.

Application Fields

Process control: in the chemical, pharmaceutical, food and beverage industries, it can be used to monitor temperature, pressure, flow, level and other physical quantities to achieve accurate control of the production process.

Manufacturing automation: In automotive manufacturing, electronics manufacturing and other fields, it can be used to measure displacement, speed, acceleration, force and other parameters, providing accurate feedback signals for automated production equipment to ensure product quality and production efficiency.

Energy management: in the power system, it can be used to monitor voltage, current, power and other parameters, to achieve effective management and monitoring of energy, and improve the efficiency of energy use.

AC 800F Controller Redundancy

Controller redundancy can be achieved by installing two  AC 800F. To ensure quick and smooth takeover by the secondary AC 800F in case the primary AC 800F fails, a dedicated  redundancy communications link through the second Ethernet  module makes sure that both AC 800F are always synchronized. All inputs and outputs are designed to support redundant  operation.
