That sounds right, its hard to find much about the module with Google though.
It sounds like there are two versions of the module - AUD1A and AUD1B:
Output:
AUD1A: output high level 3mA or low level 3mA. The output high level of the active signal is detected.
AUD1B: output high level 1500mA or open circuit state. The output high level of the active signal is detected. Output terminal with a protective diode, can be directly connected to a variety of load (including inductive load).
Not totally clear what that means though, anyone here able to explain? Perhaps that AUD1B is able to drive a directly connected relay?
