5. The analog input AI is ±10V, with a maximum operating
frequency of 10kHz, a sampling rate of 100kSPS, and a peak
sampling accuracy of ±2%;
6. When the 24V DC output power supply of the I/O interface
is used in conjunction with the DO, it serves as an active
output to provide energy to the outside and can be
connected to resistive, inductive and capacitive loads. The
one-way 24V DC power supply has a maximum output
current of less than 1A, and can be used for up to 4-way DO
at the same time, otherwise the internal protection circuit of
the system would be burned out due to overcurrent.
7. To ensure reliable and stable operation of the load, it
should be connected to an external 24V power supply in
conjunction with DO.
