Valve actuation specialist Rotork co-sponsored the annual UK Profibus Users Conference, held at Coombe Abbey, near Coventry. This event provided the suitable showcase for introducing Rotork’s latest addition to its Profibus catalogue, the Highway Termination Module. Housed in the actuator’s terminal cover, the module provides a means of connection to Profibus highways, with switchable termination resistors and a “bumpless” isolation mechanism to enable actuator connection/disconnection from the highway without disrupting communications to the other highway devices. The module itself has been engineered to enable connection of both stranded and solid core Profibus highway cables and has four conduit entries to allow both single and dual channel highways to be interfaced to the actuator. The module also maintains Rotork’s philosophy of a zero internal stub length, essential for high baud rate applications, by having separate “IN” and “OUT” cabling from the field, via the module, all the way to the Profibus card within the actuator. The new module is available for the entire IQ intelligent actuator product range.
