Sipex Corp. developed a Profibus transceiver, the SP1486E, which is designed for high-density industrial control networks.

The device's 1/8th load capability allows up to 256 transceivers on the communication bus without violating the Profibus specification. The hot swap capability does not require a shutdown of the entire system for each board insertion and desertion.

The failsafe protection minimizes noise, parasitic coupling and can prevent the CMOS inputs from drifting when the receiver inputs are floating, shorted or open. The device also complies with TIA/EIA-485, TIA/EIA-422, IEC61000-4-2 air gap (15kV) and contact discharge (8kV) standards.

The SP1486E is suitable for high-speed, bi-directional communication on multipoint bus transmission lines. It features a 2.7V differential output voltage that allows data transmission over longer distances than standard RS-485 transceivers. Moreover, the SP1486E provides a 20Mbps data rate, suitable for Profibus applications including advanced fieldbus networks, security networks, robotic manufacturing plants and industrial process control with remote sensing and metering.

The device is available now and costs $1.25 in 1,000-piece quantities.
