The following types of I/O modules are available.

· 16 Di or Do
· DC voltage/current input, 2 or 4 points
· Universal input, 2 or 4 points
· T/C or RTD input, 4 points
· Potentiometer input, 4 points
· AC current input, 4 points

In addition, remote Modbus slaves can be connected up to 12 nodes.
At the maximum of 64 analog inputs (16-bit data), 64 discrete inputs, 64 discrete outputs, 32 pulse inputs (32-bit data) plus 32 function inputs (mathematical, logic, filter, etc.) are usable. At the maximum of 120 channels can be plotted on the charts and stored at the storing cycle of 1 minute. The fastest storing cycle is 5 milliseconds for 16 channels, 100 milliseconds for 32 channels.
