Description

The Integrated circuit FZE 1658G is used to detect the signal states of eight independent input lines according to IEC 65A Type 2 (e.g. two-wire proximity switches) with a common ground (GND). For operation in accordance with IEC 65A, it is necessary for the device to be wired with resistors rated RV = 820  and REXT = 4.4 k with ± 2 % tolerance and 200 ppm TK. The input FZE 1658G has the following characteristics:
