Brand: Consen（康吉森）
Model: AO1681
Status: New/Used
AO1681 supports 16-point 4~20mA current signal output. AO1681 uses TMR architecture, and the redundant three channels are designed on the same module. AO1681 is connected to PM01 and FTA via connectors fixed on the backplane. Each AO1681 has one FTA, where there are 16 points in the FTA. When AO1681 is configured in dual redundant, two redundant modules share the FTA. AO1681 Model has extensive diagnostics on each channel, module, and functional circuit immediately detect and report operational faults by means of indicators or alarms. AO1681 supports HART communication with the instruments which has HART function.
Consen（康吉森） AO1681
The Tricon system is a highly reliable safety control system provided by Kangjisen, with a triple hardware design to improve system reliability and availability. The analog output module (AO module) of the Tricon system is an important component of the system, used to convert digital signals into analog signals for communication and control with external devices.
Specific characteristics of AO1681
According to the search results, although the specific model AO1681 was not directly mentioned, we can infer that AO1681 is an analog output module in the Tricon system. The analog output module of the Tricon system typically has the following characteristics:
Triple design: Each output point has a corresponding triple 12 bit D/A converter, which ensures that the system can still function properly even in the event of a converter failure.
Choose 2 out of 3 circuit: This circuit selects the correct output circuit and periodically checks the circuits of all channels to ensure the accuracy and reliability of the output.
Automatic voltage correction: By using a built-in reference voltage for automatic voltage correction, the accuracy of the output signal is improved.
No single point of failure: The design avoids the possibility of single point of failure, enhancing the stability and safety of the system.
