New Incremental Serial Interface (ISI) Linear Transducers
Written By klscontrols

Incremental Output Encoders with Absolute Positioning.

TR Electronic is proud to manufacture the largest selection of rotary and linear encoders in our market. Our customers benefit from the latest design and support options available in the industry. For applications which only require simple pulse count positioning, an Incremental is the encoder for you.

We are here for Manufacturing!

ISI Interface Provides a Familiar Incremental Output with Absolute Positioning!

 What is ISI?

ISI is an interface available on TR encoder products that provides ABSOLUTE positioning using a standard incremental interface. This interface sends positioning changes to your controller as pulses, using a standard incremental channel (A and B plus complements). The absolute position of your system is maintained within the encoder and can be extracted by triggering the Load In/Load Out functions. No batteries required!How ISI Works:

With ISI, changes in the encoder position are transferred by two incremental tracks. The 90° phase displacement between the two incremental signals indicates the direction of travel. This is typical of any incremental encoder with Quadrature output. What makes ISI different, and VERY valuable, is it also includes a Load Input and Load Output. Triggering the input will signal the encoder to stop producing pulses. Your device counter can now be reset to zero and the absolute position of the encoder is communicated through pulses, up to the encoder absolute position. This loads the absolute position into your control system. When the absolute position value is reached, it turns off the Load Output signal and the encoder returns to normal operation. ISI is a great solution for providing absolute position when only an incremental interface is available on the controller or drive.

Linear Position Transducers by TR Electronic
Written By klscontrols

We have partnered up with TR Electronic to provide our customers with magnetostrictive linear measurement transducers. The linear devices can be made in a rod style which can be mounted in or out of a cylinder. A profile series utilizes and extruded body housing and mounting feet for its applications. Several output options to chose from: Analog, SSI, Device-Net, Profibus, Ethernet. Connections options available: cable out, packing gland or M16 connection. Direct replacement to competitors units and backwards compatibility offer unique options and solutions. Now offering free magnets with the linear transducers. Data sheets can be downloaded from our website or TR Electronic.
