Description

The new DSR1 is designed to increase the reliability of your system. This compact, easy-to-mount DIN rail device provides signal isolation and effectively doubles your cable run.

The DSR1 Isolator / Repeater from Avtron™ Encoders is an in-line signal converter that isolates and repeats signals, perfect for connecting encoders to controllers or receivers in the environment that require a long distance and isolated, clean signals. Thanks to optical isolation, ground loops are eliminated, ensuring clean, stable signals. It's compatible not only with Avtron Encoders but also with any sensor offering digital outputs.

Built for superior performance, the DSR1 supports a wide input voltage range (3 to 10V and 10 to 28V) and works with popular driver types, including differential line drivers, single-ended push-pull drivers, NPN, and PNP configurations. It accepts both single-ended and differential input signals from sensors with line driver or open collector outputs.

Multiple driver options make the DSR1 compatible with virtually every PLC or receiver on the market. Plus, its smart engineered circuitry provides controlled termination impedance, minimizing ringing and reducing both common-mode and differential-mode noise on your cables.

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.
Missed Pulses

Errors made by an encoder when a pulse should have been generated due to movement but was not. They are often caused by contamination on optical disks that cause a line to be missed.
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.
Pulses

Pulses are also known as counts and are the low voltage output transitions which indicate movement of the encoder. Encoders are rated by resolution or PPR (pulses per revolution). Pulses are not the same as lines.
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.
Shaft Current

The undesirable electrical current flow common to motors controlled by variable speed drives. This current attempts to circulate within the motor or discharge to ground. Avtron encoders are protected against shaft currents.
