Incremental Encoder Controller
The MR340 series fiber optic incremental encoder system is an innovative all-optical design immune to any electro-magnetic interferences such as magnetic fields, lightning, voltage, and other harsh environment conditions. The MR340-1 Controller works with any of the MR34X series fiber optic incremental encoders – rotary or linear.
The Sensor is connected to the Controller via an industry-standard 62.5/125μm duplex multimode fiber optic link. As the incremental code media passes through the Sensor’s internal optical pick-up, the phase output of two light beams create the classical A/B quadrature signals accessible via the controller’s electrical interface.
The controller keeps track of position and also calculates the RPM or linear speed of the connected encoder. Both position and speed can be read via Modbus/RS485 serial interface, USB or analog output. The analog output can be configured for either ± 10V or 4-20mA output.
The system has built-in diagnostics and can signal to the user any anomaly occurring during operation.
