PROFIBUS PA Hardware Design (H1-4W)

Übersicht:

The PROFIBUS PA/Foundation Fieldbus Hardware Design Package includes the schematics and development documentation etc. for a small size universal fieldbus interface. It provides fieldbus functionality for separately powered field devices. The H1-4W design separates the I.S. fieldbus from the non-I.S. application hardware and allows for explosionproof devices to be connected to an I.S. fieldbus segment.

Technische Daten:

Fieldbus interface IEC 61158-2
Fieldbus current <12mA
Galvanic isolation 1,500V DC
TA -40°C…+85°C
Design according to ATEX 95 (IEC 60079-0, IEC 60079-11, FISCO IEC 60079-2)
Renesas M16C62 microcontroller
256kB Flash, 256kB RAM, 8kB EEPROM
Sync./async. serial interface
16 I/Os (3 interrupts)
Size (LxWxH): 40.0 x 55.0 x 10.5mm

Technology:

A powerful internal CPU and substantial resources to integrate complex PROFIBUS PA profiles or LAS function for Foundation Fieldbus are main features. The Medium Attachment Unit (MAU) is implemented as a discrete circuit, which allows to replace the discontinued SIM1 and μSAA22Q ASICs with standard components.
