11.1 I/O Electrical Features

11.1.1 Electrical Features of Input Signal

The internal circuit of opto-isolated input (Line 0) is as follows.

Note

● The maximum input current of Line 0 is 25 mA.

● Make sure that the input voltage is not from 1 VDC to 3.3 VDC as the electric status

between these two values are not stable.

● The breakdown voltage is 30 VDC. Keep voltage stable.
