DC302
Foundation Fieldbus Remote I/O
The DC302 Fieldbus Remote I/O makes the integration of Fieldbus and conventional I/O easy. It is a single integrated easy to use piece of equipment including power, control, networking and I/O under one compact device requiring less panel space than other solutions. The DC302 is an integral part of SYSTEM 302 but also integrates into other systems supporting Foundation Fieldbus.
Some Characteristics:
|
Communication
|
FOUNDATION Fieldbus on 31.25 kbit/s voltage mode according to IEC 61158-2
|
|
Power Consumption
|
Quiescent 12 mA
|
|
Output Impedance
|
Non-intrinsic safety from 7.8 kHz - 39 kHz should be greater or equal to 3 k. Intrinsic safety output impedance (assuming an IS barrier in the powersupply) from 7.8 kHz 39 kHz should be greater or equal to 400
|
|
Function Blocks
|
Up to 20 Dynamically Instantiable Function Blocks.
The Function Blocks available allow simple and complex control strategies to be placed inside the field device, making the field device and integral part of the control system. In order to fully benefit from the Function Blocks in the device a True Foundation Fieldbus system is recommended.
