WirelessHART Adapter SWA70

Smart WirelessHART interface module
with power supply for field devices

Application

The WirelessHART Adapter SWA70 is an interface module for the wireless
transmission of 4 to 20 mA/HART signals from connected field devices to a
WirelessHART Fieldgate. It is powered by either a battery pack or power supply units.
The WirelessHART Adapter can be used in hazardous and non-hazardous area for
applications, such as:

• Process optimization:
By connecting the WirelessHART Adapter, it is possible to monitor and optimize
plant sections with less cost and effort.

• Level monitoring in tanks and silos:
Measured values together with the device and battery status are transmitted at
regular intervals to a higher-level system.

• Plant condition monitoring:
Wireless devices are mounted at critical points in the plant which are not normally
connected to the control room due to their limited accessibility or wiring costs.
Improved data flow and diagnostics increase plant reliability and safety.

Your benefits

The flexible adapter concept offers the following advantages:

• HART devices are quickly upgraded to WirelessHART technology

• Fast integration of 4 to 20 mA field devices into a WirelessHART network

• One 4 to 20 mA field device and up to four HART field devices in multidrop mode can
be connected to a WirelessHART Adapter

• Burst mode and event notification supported

• Remote and difficult-to-access HART devices are connected to the control room
without expensive cabling

• Easy planning, quick installation and integration

WirelessHART Adapter SWA70

Function and system design

WirelessHART WirelessHART adds wireless capabilities to the HART protocol, while ensuring compatibility with

existing HART devices, commands and tools.
A WirelessHART network comprises:

• Wireless field devices

• Wired field devices with a connected WirelessHART Adapter

• Gateways responsible for communication between devices and host applications

• Network and Safety Manager responsible for configuring, managing and monitoring the network

The WirelessHART protocol may not be used to replace the wiring in the case of safety applications
with a control function.

SWA70

System design The WirelessHART Adapter SWA70 transmits information to a host application via a WirelessHART

The WirelessHART Adapter SWA70 acts as an add-on interface for wireless communication with
HART field devices or 4 to 20 mA field devices.
It is powered by either a battery pack, a wide range power unit or a DC power unit. The DC power unit
can use solar power, for example. A special long-life, high-power battery is used as the battery.

The WirelessHART Adapter SWA70 supports the following functions:

• Power supply for a HART field device or a 4 to 20 mA field device

• Power supply of up to four HART devices in the multidrop mode with a wide range power unit

• Connection of up to four externally powered HART field devices in the multidrop mode

• Scaling of the current signal from a connected 4 to 20 mA field device

• Burst mode and event notification for the WirelessHART Adapter and the connected field devices

Fieldgate. The figure below shows a typical WirelessHART network architecture.
