I’m familiar with analog signals and HART signals in instruments; what kind of signal is S3L?
Thread Content
It doesn’t refer to SIL certification; rather, it means that the output signal is an S3L digital signal. Please take a look at the outputs of certain GF brand products. I searched on Baidu but found no information. Could anyone with expertise explain this?

9600, is it a communication output, with a baud rate of bps?
What kind of signal is this? Are there any tools that can convert an analog signal into this type of signal? It’s the brand GF that uses it
I think it’s serial communication, 485 to 232
If the other party is capable of receiving this signal, but our instruments only provide 485 signals or 4-20mA signals, what should we do?
Is this an on-site temperature sensor or a digital display? There are two ways of output: Hart or communication signals. Wouldn’t it be simple to feed the Hart signal directly into the AI card? The recipient side needs to have a 485/232 communication module for the communication signal
There are modules with 485 to 232 conversion; if it’s 4-20mA, a secondary meter can be added to convert the signal.
