with 2 SSI absolute value encoders

The S-DIAS SSI Interface Module SI 021 can evaluate two absolute value

encoders via the S-DIAS interface.

The SSI interface is designed for SSI encoders (e.g. absolute angle

encoded length measurement rods...). Non-coded and Gray coded (Gray

code is internally converted to binary) sensors are supported.
