Pulse counting: The counting sampling frequency is 1KHz, and

the width of the high and low levels of the pulse is required to

be >1mS; When each channel has a transition from 1 to 0, the

count value is incremented by 1; the maximum count value of

each channel is 4 bytes: FFFFFFFFH.

Digital Output

Relay 250V*5A(AC) or 14V*20A(DC)

Can be set as electrical level mode or pulse mode output, the

pulse width can be set from 0.1S to 25S

Support maintaining the relay state after power failure
