Parker Hannifin extends its AC890 Modular Systems and AC890PX High Power Systems AC drives with high resolution analogue input and encoder option boards in order to provide extra inputs and outputs for electronic line shaft applications, machine tools and motion control tasks. The 8903-EP encoder option board features an incremental encoder input for a reference encoder, and a synthetic encoder output. The encoder input provides optically isolated differential inputs on channels A, B and Z. All inputs are compatible with RS422 and RS485 encoders, as well as encoders that provide output voltages as high as ±30V. The board embeds all the decoding logic required to interface the encoder input to the drive’s microprocessor.
