Encoder Specifications
Type:
Incremental, dual channel
Supply:
12V, 250 mA. 12V, 10 mA minimum inputs isolated with differential transmitter, 250 kHz maximum.
Quadrature:
90°, ±27 degrees at 25 degrees C.
Duty Cycle:
50%, +10%
Requirements:
Encoders must be line driver type, quadrature (dual channel) or pulse (single channel), 8…15V DC
output (3.5…6V DC when jumpers are in 5V position), single-ended or differential and capable of
supplying a minimum of 10 mA per channel. Maximum input frequency is 250 kHz. The Encoder
Interface Board accepts 12V DC square-wave with a minimum high state voltage of 7.0V DC. With
the jumpers in the 5V position, the encoder accept a 5V DC square-wave with a minimum high state
voltage of 3.1V DC. In either jumper position, the maximum low state voltage is 0.4V DC.
