Endress+Hauser has opened up new applications for its SWA70 WirelessHART adaptors by adding a wide input range power supply in addition to the well-proven battery pack option. This allows connection to line voltages of 24-230 VAC/DC where available, with the added advantage that the adaptor can be used to power up to four HART devices in multidrop mode. The result is simpler installation and a saving in additional power supplies.
The SWA70 adaptor allows wireless transmission of the 4-20 mA/HART signals of connected field devices to a WirelessHART Fieldgate.
Along with the new possibilities arising from the wide-range power supply, the flexible adaptor concept offers other advantages:
* HART devices can be quickly upgraded to WirelessHART technology, no matter whether a power supply is present or not.
* Remote or difficult to access HART devices can be connected to the control room without the need to lay cables.
* Planning, installation and integration is quick and easy.
