FEATURES

INTELLIGENCE

The Bray Controls Series 66 DeviceNet Analog Interface enables a Pneumatic Valve Positioner to operate in Modulating service when connected to a DeviceNet network. Commands from the network can
direct the Positioner to move the Valve Actuator to
any position between fully open and fully closed,
inclusive. Actual valve position sensed by the Positioner can be transmitted to other devices over the
network. Module status, including both network and
diagnostic information, can be transmitted over DeviceNet and visually displayed through LED indicators. Both power and data wiring are supplied
through a single DeviceNet cable connection.

The Series 66 DeviceNet Analog Actuator Interface
is microprocessor controlled, or smart, using firmware specifically designed to complement the capabilities of Bray Pneumatic Valve Positioners. It produces one 4-20 mA DC analog output (AO) to drive
the Positioner, and reads one 4-20 mA DC analog
input (AI) valve position signal from the retransmission feature. The Process Controller or PLC communicates with both analog I/O points through a single
network address, or MAC ID. Both I/O points, as
well as some diagnostic parameters, are continuously monitored and accessible through the DeviceNet connection.

DeviceNet

OPERATION

DeviceNet is an economical fieldbus network used
to connect industrial devices such as sensors, actuators and motors while providing access to the intelligence present in these devices. DeviceNet allows up
to 64 devices to communicate with each other over a
single cable that supplies both communication and
power. This simplifies field wiring, enhances functionality, and reduces total system cost.

The Series 66 DeviceNet Analog Actuator Interface
is easy to install and configure. Network wiring is
done through a single DeviceNet standard five-pin
connector, similar to plugging a mouse or keyboard
into a personal computer. Configuration is done with
Electronic Data Sheet (EDS) files without adjusting
potentiometers or selector switches. All configuration settings are saved in non-volatile memory so
they will survive power outages. An entire Actuated
Valve Assembly (shown above) requires only a single DeviceNet connector and one air supply connection to operate.
