Description

The new DSR4 is designed to increase the reliability of your system. This simple DIN rail equipment will provide isolation to your signals, split them into other devices or double your cable run. All in one compact and easy to mount device.

This Isolator / Signal Splitter from Avtron™ Encoders is an in-line signal converter that allows the user to isolate and split signals from one encoder up to four separate outputs. Each channel is optically isolated from the others, which eliminates ground loops. Each channel is independently powered, so the output logic levels can be different for each output. Signal processing can be added if needed. The Isolator/Broadcaster is designed for use with Avtron Encoders or any sensor with digital outputs.

It is designed for superior performance over a wide range of input levels (3 to 8V and 8 to 28V), and popular driver configurations (differential line driver, single ended push-pull driver, NPN and PNP). Input signals to the isolator can be single-ended or differential, from a sensor with line driver or open collector outputs.

Driver options are available that are compatible with virtually every PLC or receiver!

The smart engineered circuitry provides a controlled termination impedance for the signal cabling, which minimizes ringing and noise pick-up (both common-mode and differential-mode) on the cable.

PRODUCT GLOSSARY

A Quad B

A Quad B refers to the set of output quadrature signals from an incremental quadrature encoder to indicate speed and direction, including complements: A, A NOT, B, B NOT (, , , ). Most Avtron encoders offer A Quad B output at no extra cost. For more information on quadrature- Wikipedia: http://en.wikipedia.org/wiki/Quadrature_phase
Complements

Also known as complementary outputs. To ensure that signal noise does not cause errors between the encoder and the controller, many encoders output signals that are driven in exactly opposite directions: when A goes high, A NOT goes low (, ); when A goes low, A NOT goes high. Controllers which see a transition in A, but not in the A NOT signal, would report a quadrature error.
Encoder

A device which indicates position and speed via a set of digital outputs. Incremental encoders output quadrature (A Quad B) signals, and may add a marker pulse once per revolution. Absolute encoders typically indicate position via a digital message, a set of parallel outputs, or analog values.
False Pulses

Pulses output by the encoder when no pulses should be output. They are often caused by contamination on optical disks that is misread as a line on the optical disk.
Incremental Encoder

An encoder that produces pulses in proportion to distance moved or rotated. Incremental encoders can also have a marker pulse Z, Z NOT (, ) once per revolution to provide a position reference. Avtron produces a full range of incremental rotary encoders.
Isolated Outputs

Isolated Outputs provide two or more completely separate output signals from the encoder. These separate signals can be wired to two or more devices, or used for redundant control systems for more uptime. Avtron isolated encoder outputs are always created using fully redundant electronics and sensors, isolated from each other and from the housing for maximum reliability.
Line Driver

The chip or output circuit that forms the electrical pulses output from the encoder. Avtron has extremely advanced line driver technology to prevent damage from overvoltage and short circuits. Avtron offers optional high-power line drivers to permit Avtron encoder signals to travel farther down long wires to remote controller/drive locations without the need for repeaters or amplifiers.
Magnetic Encoder

Magnetic and magnetoresistive encoders typically use a magnetized rotor with north and south poles lined up around the perimeter of the disk. A magnetoresistive sensor detects the transitions, and these are the counts or pulses generated by the encoder. Magnetic encoders withstand dirt, dust, water, and temperature changes far better than optical encoders.
Optical Encoder

An Optical Encoder typically uses a light source shining through, or reflecting off, an optical disk with lines or slots that interrupt the beam of light to an optical sensor. Electronics count the interruptions of the beam and generate the encoder�s output pulses.
PPR

Pulses Per Revolution. Most Avtron encoders output quadrature pulses, with four times as many lines as pulses. Often lines can be counted in the drive/speed controller for higher resolution applications.
Quadrature

To determine which direction an encoder is revolving, encoders output quadrature signals: two streams of pulses, A & B, generated at 90� timing angles. (Also called A Quad B) A leading B indicates rotation in one direction; B leading A indicates the encoder is rotating in the opposite direction. Example: �A leads B with clockwise rotation as viewed from the encoder face on an HS45 encoder." Many encoders with quadrature outputs also have complementary outputs: A NOT and B NOT signals.
Quadrature Errors

Failures of the encoder to generate properly formatted quadrature signals. Most typically, these are failures to create the proper 90� signal separation between the A and B channel outputs, with a less than perfect stream of square waves. Most controllers, when presented with a quadrature error, will report a drive fault or encoder fault and then shut down.
Rotary Encoder

A rotary encoder provides position and/or speed feedback information about a rotating shaft. Rotary encoders may be hollow shaft, no-bearing modular, coupled solid shaft style. They may provide absolute positioning information, or incremental velocity feedback. Avtron rotary encoders are designed and built to be far more reliable than ordinary rotary encoders. Avtron encoder white papers on our blog provide more details of how and why Avtron rotary encoders are more reliable.
Twisted Pair Cable

Incremental and absolute encoder signals should be carried over twisted pair cables. Twisted pair cables enable the elimination of external noise signals, as the signals show up as "common mode" noise on both wires in the pair. The controller wired for differential communication will remove the external noise from the encoder signal. When wiring Avtron incremental encoders, be sure to wire the complementary signals (ex: A, A/) in one twisted pair. Do not mix phased signals (ex: A, B) in the same twisted pair. For absolute encoders, follow the bus recommendations for using the twisted pairs in the required cable type.
