Electronic Modules Dual Encoder USB Converter EMDR1-SS, EMDR1-QS
Position Sensors & Encoders
The Dual Encoder to USB Converter translates encoder position to industry standard USB 2.0 format that can be read by a computer. Each module can handle signals from two encoders. Modules are available for SSI absolute encoders, as well as quadrature incremental encoders. The module can be programmed through the USB interface for number of bits with absolute encoders. For incremental encoders, count mode (X1, X2, X4), reset, preset, and preset/reset on index are programmable through the USB input. Incremental encoder counter register length is programmable, up to 32 bits. The Encoder to USB Converter is ideal for system setup and debugging, data acquisition and PC based control applications. 3-meter USB cable included. *Optional programmable data sample function allows module to automatically capture readings on an accurate time clock.
