About the Model 494.49 Quad Encoder Interface Card
The Model 494.49 Quad Encoder Interface is a mezzanine card that resides
in one of the slots on the Model 494.40 I/O Carrier board. The Model 494.49
card can accept up to four digital transducer (encoder) signals from a Model
493.80 Quad Encoder transition board.
Supported transducers The Quad Encoder Interface card supports the following transducer types:
• SSI (Temposonics R)
• Gurley (Teledyne)
• Incremental/Velocity (includes counter selection)
• Pulse-width-modulated (PWM) (Temposonics G)
Note The digital transducer interface type that you select applies to each
of the four channels on the Model 494.49 card.
External clock output
The Model 494.49 board can also be configured to provide TTL external-
clock and external-trigger outputs to synchronize external systems (such as
data acquisition systems) to the controller clocks.
