Encoder Signal Broadcaster
The Encoder Signal Broadcaster accepts standard incremental encoder inputs, (two channels
in quadrature plus an index and complements) and can broadcast up to four encoder signals
to four independent devices. Each of the broadcast signals is optically isolated eliminating
ground loops. This compact package also allows for signal processing options, such as anti-
dither filter, integer divide-by or pulse and direction outputs, to be incorporated into each of
the four broadcast signals independently. The broadcaster is ideal for driving multiple
receivers from a single encoder in applications like electronic line shafting or synchronization
of multiple devices to a single operation.

Optical Isolator Module
This is a versatile interface between an incremental encoder and any receiving electronics. It accepts single ended or differential
inputs and provides single ended or differential outputs in either an open collector or line driver configuration. It accommodates all
standard operating voltages from 5 to 28 VDC. Up to eight Optical Isolator Modules can be daisy-chained to provide multiple, simulta-
neous outputs to controllers or PLC's. This Optical Isolator can help clean up noisy signals by converting to a differential line driver
output. It has a 1 MHz throughput capability and can be used wherever a fast. optically isolated interface is required.
Anti-Dither Module
This module performs a specialized yet critical function for applications that may be subject to position errors due to stop/start cycles
or vibration environments that are not using the direction-detection functions provided by a quadrature signal. The Anti- Dither mod-
ule accepts A and B signals and, through internal discrimination circuitry. passes the signals through only when there has been true
movement of the encoder. This acts like 1/4 cycle of hysteresis and avoids encoder signal transition dithering due to mechanical
vibration. This is especially useful in web processes, handling and inspection systems that use conveyors and simple speed control in
applications that are subject to vibration.
Encoder Tester Module
This test module accepts input from any type of incremental optical encoder. It tests for two channels in quadrature, an index pulse,
and power to the module. It features a simple and intuitive LED indicator scheme: lights are on to indicate that a signal is HI and off
when the signal goes LO. Through combinations of terminal connections and dropping resistors (supplied), it can test open collector
outputs, and both single ended and differential outputs at all standard voltages: 5VDC, 12-15 VDC, and 24 VDC. This tester can also
be used for machine set-up (by locating the index pulse) and incoming inspection and diagnostics of encoded motors.
Serial-to-Parallel Converter Module
The serial to parallel converter takes serial data from either a SSI or RS-422 source and converts it to a 15 bit parallel output. This
replaces the high cost and noise susceptibility of long, parallel cable runs with the simplicity of a low cost twisted pair cable to inter-
face to a parallel-input PLC or controller. Serial input type is selectable along with clock speed (for SSI) or baud (for RS422). This
module accepts inputs from 5 to 28 VDC and has output options of Vout-Vin, Vout=5V regulated or Vout = Open Collector.
