BiDi Transmission Path

Mutual safeguarding between tandem controls



BiDi-Strecke

The BiDi transmission path is, for example, an advantageous solution for the bidirectional transmission of limit switches to safeguard the joint control of cranes. Information are exchanged via one shared frequency channel only to prevent an unnecessary blocking of the frequency channels. For this purpose TELETEC utilizes the proven and recognized half-duplex procedure (HDX). The transceiver distinguishes itself by its extraordinarily compact construction and offers the necessary components to meet the criteria of category 3 PL d according to EN ISO 13849-1:2006 (additionally two separated emergency stop circuits are transmitted actively and monitored internally).
