Application
The SV 210 encoder splitter has been designed for clean and trouble-free distribution of the
output signals of sine-cosine type encoders to several target units. Since on the output site the
unit provides both, sine-cosine outputs and incremental outputs, it is suitable for use with
target units with either sine or incremental inputs.
On both sine output channels the same signal format is available as on the input site, including
a reference impulse (if available on the input site). All sine-cosine signals use the differential
1 Vpp format which is most common with industrial sine-cosine encoders.
Current signals according to the 11
μ
A standard are not supported by this unit.
The two incremental output channels at the same time supply square wave signals, namely one
impulse per each sine period and one index pulse per each reference signal on the input side.
At any time the differential signals A, /A, B, /B, Z /Z are available and the output level is
settable to either TTL (5 V) or HTL (10 - 30 V) level, separately for each output channel.
The diagram below explains the correlation between sine signals and incremental signals.

(e.g. 50 increments per sine period) please refer to our Sine-Cosine Interpolator type SI251
