2 VAC D300 PSS EVE0105 A-(en)

OVERVIEW

The D300 consists of a basic device with digital controller with different communication protocols (or also

simply 4-20 mA input). Into the basic device still additional equipment can be built, like additional plug-in cards for

electrical input/output signals, position feedback and pressure sensors.

The pneumatic control is achieved with a high flow spool valve assembly. In special applications using large

actuators, boosters with increased air capacity can be added. Also available are different manifolds for

connection and gauges.

For the pneumatic connections we offer different threading in the housing; for cable glands there are adapters.

For use in hazardous areas there are approvals according to ATEX, FM, CSA ...

The device can be configured locally by means of push buttons and LCD / LED, or with PC + EDC82 Modem

connected to the service plug of the VAC D300.

By means of communication the device can be configured from the distance; or with IrCom + PC (Infrared Interface,

approx. 1 m).

Basic devices:

All devices regulate digitally and have 3 push buttons and 5 LEDS for local configuration.

Device version Indication remote configuration

“H” HART (4-20 mA) LCD or 5 LEDs by communication / IrCom / Service plug

“P” Profibus LCD or 5 LEDs by communication / IrCom / Service plug

“Q” F.Fieldbus LCD or 5 LEDs by communication / IrCom / Service plug

“F” FoxCom 5 LEDs by communication

“D” Digital (4-20 mA)

without communication

LCD or 5 LEDs by IrCom / Service plug

Additional equipment, built into the basic device:

Option Board “Position Feedback” or

1 output 4-20 mA (to be supplied externally) supplies stroke /

angles of rotation

1 alarm output becomes active with a configurable* event

Option Board “2 Binary Inputs” or

2 external switches release a control function in the SRD,

e.g. "close valve" (configurable)

Option Board “2 Binary Outputs”

2 binary outputs become active during limit value excess of the

measured valve position

Grenzwertgeber

Supplies NAMUR signals during excess or falling below of two

limit values supplies; inductiv, independent of the controller;

in normal or safety version

Pressure sensors

2 sensors measure the pressure of supply air and output y1;

the values are passed on via communication
