Encoder
Type:
Incremental, dual channel
Supply:
5V/12V Config/-5%
Quadrature:
90° +/-27° at 25° C.
Duty Cycle:
50% +10%
Requirements
Encoders must be line driver type, quadrature (dual
channel) or pulse (single channel), single-ended or
differential and capable of supplying a minimum of 10
mA per channel. The Encoder Interface Board
accepts 5V or 12V DC square-wave with a minimum
high state voltage of 3.5V DC (5V mode) and 7.0V DC
(12V mode). Maximum low state voltage is 1V DC (for
both 5V and 12V modes). Maximum input frequency is
250 kHz.

Applied noise impulses may be counted in addition to the standard pulse train causing erroneously high [Pulse
Freq] readings.
