HFBR-1515B

SERCOS, an acronym for SErial Realtime COmmunications System, is a standard digital interface for communication in industrial CNC applications. The standard defines two data rates: 2 MBd and 4 MBd and was formed to allow data transfer between numerical controls and drives via fiber-optic rings, with voltage isolation and noise immunity. The HFBR-1505A/2505A products comply with SERCOS specifications for optical characteristics and connector style, and can also be used for data rates up to 10 MBd. The international standard is IEC 1491. PROFIBUS, an acronym of PROcess FIeld BUS, is an open fieldbus standard defined for data rates ranging from 9.6 kBd to 12 MBd in selectable steps for wire and optical fiber. PROFIBUS is a German national DIN 19245 standard and a European CENELEC standard EN 50170. The HFBR-1515B STF connector is the standard optical port of the PROFIBUS optical fiber version. The HFBR-1515B/2515B complies fully to the technical guideline using Plastic Optical Fiber up to 1.5 MBd, and can also be used for data rates up to 10 MBd. Please contact Hewlett-Packard regarding any future plans for a 12 MBd device. INTERBUS-S, a special open Sensor/Actuator Bus, is finding a broad acceptance in the factory automation industry. The HFBR-1515B was specially designed for this application and is recommended as a powerful transmitter for use with 1 mm POF and 200 5m HCSF fiber. The optical transmission guideline is a supplement of the German National DIN E 19258 standard draft. On the European level, prEN 50254 is the draft of the INTERBUS-S fieldbus. The HFBR-1505C transmitter can be used in conjunction with the HFBR-2505A receiver.
