... The NER output which is constructed as an open collector and is also short-circuit proof reports the fault via the connected line. The error input TNER can be linked to message outputs of other ICs and allows iC-WE to report a system fault message. If the supply voltage VCC cancels, NER becomes highly resistive. ...

... A mismatch between the iC-WE and the line influences the level of the initially injected wave and produces reflections at the driver end. The output signal may have a number of graduations. Nonetheless, lines with characteristic impedances in the range 40 to 150 Ω ...

... CHAN3 Fig. 4: Balanced data transmission EXAMPLE 2: Incremental encoder Fig. 5 shows the iC-WE being used in an optical encoder system together with the iC-Haus incremental encoder iC-WT. The iC-WT device is an evaluating IC for photodiode arrays used in incremental lengths and angle measuring systems. It preprocesses the sensor signals for transmission with line driver iC-WE. At the receive end the programmable logic controller (PLC) interface can be via optocoupler ...

... LINE DRIVER The error input TNER on the iC-WE can be utilized to conduct a fault signal from the incremental encoder to the output NER and then to the receiver. For protection against voltage peaks from the cable, the state input TRI is wired to the RC combination R1, R2 and C5, which can be dimensioned for levels the PLC ...
