SIGNAL ISOLATOR SERIAL

This high level of integration density combined with the low power consumption is a key enabler for highly compact industrial control products. When compared with alternative solutions, ISOFACE™ digital input ICs enable up to four times more channels on the same PCB area. The ISOFACE™ digital input ICs offer a robust integrated galvanic isolation of 500V AC (EN60664-1, UL508).

To ensure uncompromised data-transfer with the microcontroller the ISO1I813T supports CRC-checking of the serial communication. To support very compact system designs daisy-chaining of multiple ISOFACE™ digital input ICs is supported. The microcontroller or bus-ASIC can be connected either via a high-speed SPI Interface or using a parallel 8-bit interface to the ICs. This is of particular practical relevance when an isochronous time-stamp of the status of a complex machine or equipment is required. Therefore, they are ideally suited for high-precision or high-speed applications like bottling machines or paper and printing industries.Ī feature only available with the ISO1I813T is the capability to synchronously capture the input signals from multiple input ICs. The ISOFACE™ digital input ICs support sampling speeds of up to 500kHz per input channel, substantially exceeding the speed of solutions using opto-couplers. zero filter time, is offered with both types. The ISO1I813T allows to individually program the filter setting for each of the channels. In case of the ISO1I811T, jumpers on the PCB can be used to select one of the four possible settings. To improve EMI robustness of the system solution, the 8 input channels are equipped with adjustable deglitching filters. In consequence, more compact designs of input card solutions become possible with ISOFACE™. The precise characteristic of the current sink of the IC’s inputs reduces the power dissipation per channel by a factor of up to 2.5-times compared to solutions using resistors and opto-couplers. Up to 8 inputs according to IEC61131-2 (Type 1/2/3) can be connected per IC. The digital input ICs can be directly connected to digital inputs like sensors or switches and the microcontroller or bus-ASIC.

The ISOFACE™ ISO1I81xT product family ISO1I811T and ISO1I813T of galvanically isolated 8-channel digital input ICs sample input data from digital sensors and switches.
