DC-303 Profibus-PA Remote I/O
|
|
The DC303 Profibus-PA Remote I/O makes the integration of Profibus 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 DC303 is an integral part of SYSTEM302 but also integrates into other systems supporting Profibus.
Some Characteristics:
|
Communication
|
Profibus-PA on 31.25 kbit/s voltage mode according to IEC 61158-2.
|
|
Power Consumption
|
150 mA (External Power)
|
|
Output Impedance
|
Non-intrinsic safety from 7.8 kHz - 39 kHz should be greater or equal to 3 kΩ. Intrinsic safety output impedance (assuming an IS barrier in the powersupply) from 7.8 kHz – 39 kHz should be greater or equal to 400 Ω.
|
|
Function Blocks
|
Up to 16 Discrete Input Function Blocks (DIs) and up to 8 Discrete Output Function Blocks (DOs). The DC303 has a Built-in Flexible Function Block (FFB) for logic execution such as: AND, OR, XOR e NOT and functions as: Timer On-Delay, Timer Off-Delay, Timer Pulse, Pulse Counter Down (CTD), Pulse Counter Up(CTU), Flip-Flop RS and Flip-Flop SR.
