• Signal conversion to many digital formats (Pulse/Direction, Up/Down Pulse, Parallel out, etc.).

• Conversion of encoder signal to many popular serial formats (USB, RS-422/485, CANbus, etc.).

• Analog output of encoder position, speed, or acceleration in many voltage ranges.

• Video synchronization and on-screen-display capabilities.

Signal Translator

EI-701 Encoder Signal Translator

Translates encoder signals between Single Ended and Differential, voltage levels from 5 to 24 VDC and amplifies encoder signals for transmission over long lines. Eight channels (2 encoders with index or 4 encoders w/o index) of open-collector or active-driven outputs. Opto-Isolation available.

EI-702 Encoder Signal Processor

Converts encoder quadrature signals to Pulse/Direction or Up-Pulse/Down-Pulse or conversion of Pulse/Direction or Up-Pulse/Down-Pulse to quadrature with adjustable index period for encoder simulation and testing. Back-step filter feature is also available. Two or four encoder capability. Opto-Isolation available.

Interpolation Processor

EI-711 Quadrature Output

Interpolates Sin/Cos from two encoders up to 8,192 times. Output is quadrature with an index reference from the encoder. Opto-Isolation available.

EI-712 Absolute Output

Interpolates Sin/Cos encoder signals up to 8,192 times. Output is 16 bit Parallel. Encoder Index zeros output. Opto-Isolation available.

EI-713 High Speed Parallel Data Output (Tachyon™)

Interpolates Sin/Cos encoder signals up to 255 times. Three million conversions per second. 24 bit Count Data Output to customer data acquisition. Opto-Isolation available.

Synchronization Processor

EI-721 Non-Integer Encoder Countdown (Omnicoder™)

This module will divide an encoder signal by an integer or non-integer value. When using a sin/cos encoder input, output jitter of less than 1 arc second is possible. Opto-Isolation available.

EI-722 One Encoder Input to Four Encoder Outputs (Multicoder™)

Using the Omnicoder™ technology, this module synchronizes four encoder outputs to a single encoder input. The countdown ratios between the outputs and input encoder can be individually set to integer or non-integer values. Opto-Isolation available.

Analog Output

EI-731 Two-Channel Encoder to Analog Output

Analog outputs can be a variety of voltage ranges with 12 bit resolution. The dual analog outputs can represent position and speed for a single encoder, or with two encoder inputs, each analog channel can represent the position or speed of each encoder. Channels can be summed internally for higher output resolution. Sin/Cos interpolation available.

Serial, USB and BUS Protocol

EI-741 Serial, USB, Industrial Bus Interface

Encoder count data is available over an RS-422/485 port, a USB port, or a variety of industry standard bus protocols such as MODBUS, CAN, SSI or Profibus. Sin/Cos interpolation available.

Video Processor

EI-751 Encoder Capture Synchronized to Video Signal

Encoder count data from up to 4 encoders is captured simultaneously on a trigger from the start of video frame or from an external trigger. Count values are transferred serially in one of the EI-700 supported bus protocols (See EI-741). Sin/Cos interpolation available.

EI-752 On-Screen Video Display of Encoder Count Value

Encoder count data from up to 4 encoders is captured simultaneously on a trigger from the start of video frame or from an external trigger. Encoder count values are added to the video signal for display on a video monitor. Video frame number and text can also be user defined. Sin/Cos interpolation available.
