　　AM811F signal unit

　　Communication module AM811F

　　AM811F communication unit

　　The AM811F analog module is a device used for measuring and controlling analog signals. It usually consists of analog input ports, analog output ports, and digital interfaces, which can convert analog signals into digital signals and perform corresponding processing and control.

　　It has the following main characteristics and functions:

　　Suitable for single or redundant applications: The AM811F analog module is suitable for single or redundant applications and has 8 unipolar analog output channels.

　　Self diagnostic function: This module has a self diagnostic function and can cycle through self checks. If problems such as low process power supply to the output circuit, output current less than the output set value (and output set value greater than 1mA, i.e. open circuit state), and output circuit failure to provide the correct current value are detected, the module will report corresponding external channel errors or internal channel errors.

　　Report Module Error: In a redundant pair, if the module bus master detects issues such as output transistor errors, short circuits, checksum errors, internal power supply errors, status link errors, watchdog or incorrect OSP behavior, the module will report a module error.

　　Current range: The current output range of each channel is 4-20mA.

　　Isolation and protection: 8 channels are isolated from the ground and have analog input short-circuit protection to ZP or+24V.

　　Hart Direct Communication: Supports the function of Hart Direct Communication.

　　In addition, the AM811F analog module also has high-performance digital signal processing capabilities, which can operate within the operating temperature range of -25 ° C to+70 ° C, and has an IP20 protection level, suitable for use in some harsh environments.

　　External channel error report: If the process power supply to the output circuit is too low, or the output current is less than the output set value and>1 mA (open circuit), the module will report an external channel error (only reported on the active channel).

　　Redundant application support: In redundant pairing, the module bus master station will command the module to enter an error state to ensure system stability and reliability.

　　Current output range: The current output range of the 8 channels of the module is 4-20mA.

　　Isolation and Protection: This module has a ground isolation design and provides analog input short circuit protection to ZP or+24V.

　　Communication function: AM811F supports direct communication with HART, facilitating communication and data exchange with other devices.

　　In addition, the AM811F analog module also has the following specifications:

　　Input voltage and output voltage: 24V DC.

　　Output current: 1A.

　　Working temperature range: -25 ° C to+70 ° C (or -40 ° C to+85 ° C, depending on information from different sources).

　　Storage temperature range: -40 ° C to+85 ° C.

　　Protection level: IP20.

　　Product size and weight: may vary depending on specific manufacturer and model, but the general size is 100mm x 50mm x 20mm, with a weight of approximately 1.2kg.

　　The application fields of analog modules are very extensive, including automation production, instrument control, optoelectronic control systems, etc. In automated production processes, analog modules can be used to monitor and control various process parameters to ensure the stability of the production process and product quality. In the field of instrument control, analog modules can be used to detect and control parameters such as temperature and humidity. In optoelectronic control systems, analog modules can be used to convert digital to analog signals to control corresponding devices and devices.
