Multifunctional Display Module MOD 20
Display with programmable inputs and outputs for Absolut-Encoder with SSI interface and Incremental Encoder
MOD 20 - a programmable multifunctional display module alternatively for one absolute single- or multi-turn encoder with SSI or parallel interface and a resolution up to 30 bit or one incremental encoder. Display parameters are fully programmable. MOD 20 has the usual standard function of a display module, but additional 9 control outputs, which can be programmed separately by 24 cam switches as comparator, cam switch or pulse switch. Easy programming by four front-panel keys or by PC with RS232 interface.
SSI-Interface
For operation of one absolute single- or multiturn- encoders with resolution up to 30 bit with serial SSI-Interface.
Incremental-Input
For operation of one incremental encoder with 3 or 6 output channels, RS422 line driver or push-pull outputs. Optically insulated with optocoupler.
Display-Scaling
Scale factor, adjustment values and counting direction are free programmable.
Programmable Control-Inputs
6 optically insulated control-inputs are programmable for various functions, e.g. storing of display data or enable of counter.
Programmable Control-Outputs
9 optically insulated control-outputs, which can be programmed separately by 24 cam switches as a comparator, cam switch or pulse switch. The cycle time is only 250 µs.
Analogue-Output
1 optically insulated programmable analogue-output, which can be used as voltage or current output. High precision D/A-converter with 16 bit resolution.
Parallel-Interface
Optically insultated input for operation of one absolute encoder with parallel output. Optically insulated output for data output of position data or velocity data in binary, gray or BCD code.
