About the Model 493.80 Encoder Interface Board
The Model 493.80 Encoder Interface board converts four channels of
differential RS-422 encoder signals into TTL encoder signals that are
compatible with the Model 494.49 Quad Encoder Interface card. In addition,
the Model 493.80 board can supply DC power to each of the four encoders.
The Model 493.80 board includes jumpers that configure the board for the
following digital transducer types:
• SSI devices–such as Temposonics R transducers, Gurley and other
absolute encoders
• Non-SSI devices–such as incremental encoders, and PWM devices
such as Temposonics G transducers.
