	AS-i bus termination: Increased safety and longer cable



			Improved data transfer due todefined bus termination Devices with protection rating IP 67, for direct installation in the field at the end of the AS-i cable. AS-i termination: Passive bus termination to extend the cable length to max. 200 m. Use in conjunction with repeaters possible, overall length up to 600 m. Works with every topology: star, ring, line and open tree structure. Fast, easy mounting using FC insulation displacement connector. The communication of an AS-i network can be considerably improved by the connection of a suitable terminating resistor. It is composed of an inductance, resistor and capacitor. Thus reflections on the cable are minimised, safety and the signal-to-noise ratio are increased. Another advantage is that an AS-i network with more than 100 metres of cable length is made possible. As flexible tree, ring, star and line topologies are possible with AS-i, there are no clear rules as regards the possible cable length. Empirical measurements with different arrangements have shown, however, that up to 200 m are possible in many networks. The bus termination is an entirely passive interface, easily mounted at the end of the cable furthest away from the AS-i power supply. Typical applications Use at the end of the cable if more than 100 metres of AS-i cable are to be used Increasing the signal-to-noise ratio and the message quality For increased safety with respect to interference in Safety at Work applications If incorrect messages occur frequently and the cause cannot be identified Extension of the AS-i cable with repeaters to up to 600 metres between two slaves AC1147 - Passive AS-i bus termination (AS-i termination plug) Accessories E70096 - Socket M12 - AS-i flat cable - FC insulation displacement connector AC1145 - eASI-Tester - Local diagnosis of the AS-i network AC2225 - AS-i repeater - Extension of the AS-i network by another 100 m AC1216 - AS-i power supply 115/230 V AC
