Performance characteristics:

Processor and Memory: 32-bit RISC processor with 256KB of data memory and 480KB of programme memory to support more complex control programmes and large amounts of data storage and processing.

Input and output configuration:

Analogue input: 8 analogue input channels, signal types can be configured as 0...+5V, -5...+5V, 0...+10V, -10...+10V, 0...20mA, 4 ...20mA, Pt100 (2-wire or 3-wire), etc., can flexibly access a variety of analogue sensor signals.

Analogue output: 4 analogue output channels, the output signal range is - 10...+10V, 0...20mA, which can meet the control requirements of a variety of actuators.

Digital inputs: 24 digital input channels, which can be easily connected to digital sensors, switches and other devices to achieve the monitoring of equipment status.

Digital output: 16 digital output channels, can be used to control relays, solenoid valves and other actuators, to achieve the switching control of equipment.

Communication interface: support RS-232, RS-485, Ethernet and other communication protocols, can achieve rapid data communication with the host computer, other controllers or intelligent devices, to facilitate the construction of distributed control systems, to meet the communication needs of different industrial scenarios.

Application areas:

Industrial automation: In various industrial production processes, such as chemical, pharmaceutical, food and beverage industries, it can be used as the core control unit to achieve precise control and monitoring of production equipment to ensure the efficient and stable operation of the production process.

Process control: It is suitable for production process control in petrochemical, metallurgy, electric power and other industries, and it can accurately control physical quantities such as temperature, pressure, flow rate, etc. It can realise real-time monitoring and automatic adjustment of process parameters through its rich input/output interfaces and powerful computing ability.

Intelligent building: It can be applied to building automation system in intelligent building, centralised control and management of air-conditioning system, lighting system, ventilation system, etc. It can automatically adjust the operating status of the equipment according to the environmental parameters and users' demands, improve the energy efficiency and comfort of the building, and achieve energy saving, emission reduction and intelligent management.

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.

Product Benefits
