I/O user Interface is designed for processing of binary input and control (setting) binary
output. Binary output is open in the default configuration. Insulation strength is 1.5 kV. The
pins are isolated from each other with the same strength.
The input circuits are bipolar and allow connection as needed with common plus or minus
(according to connection of an external voltage).
