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.
