TI claims first cross-wire immunity transceiver for fail-safe installations
August 18, 2010 // Jean-Pierre Joosting
Texas Instruments has introduced a symmetric polarity transceiver that protects the system from communication losses and potential damage should the signal wires be inadvertently reversed during installation or maintenance.
The SN65HVD96, using TI's patent-pending SymPol™ technology, provides high bus fault protection, making it desirable for harsh industrial environments where third-party installers often make the connections. The inverted bus wires are detected internally and corrected automatically, eliminating the need for intervention by the controller or operator without the need for firmware changes.
Applications that can benefit from this technology include heating, ventilating, and air conditioning (HVAC) equipment, surveillance cameras, surveillance IP network cameras, building automation, industrial lighting, and other industrial applications. This device works well with isolation devices such as the company's ISO7241C. TI also provides IBIS models for the SN65HVD96, which designers can use for simulations.
A key feature is reversed-wire-immunity which saves the technical time-consuming fail search should a crossed-wire mistake be made. Further, the device uses the same pin-out as RS-485 to eliminate the need for board redesigns.
Bus pins survive faults of up to -35 V to +40 V, minimizing damage from direct shorts to typical 24 Vac HVAC supplies, while high input impedance for up to 32 nodes allows multiple nodes on a single network, reducing system cost by eliminating repeaters.
