2-2 Set Up A System
Hardware Requirements
To build a simple fieldbus system, you need:
Power supply
Power conditioner
Fieldbus cable
Field devices
Connector blocks
Terminal blocks
Terminators
1757- FFLD linking device
Personal computer
Power Supply
The following power supplies are available according to the referenced
Fieldbus Foundation Physical Layer Profile Specification:
You can configure power supplies to provide dual redundancy as long as they
meet the IEC/ISA Physical Layer Standards requirements. It is not acceptable
for example, to merely parallel two power supplies.
A typical power supply for a small network is a SOLA SDN 5-24-100. 5A, 24
VDC output, 110 AC input. For more specifications on power supplies, see the
Power Considerations section on page 2-2.
Power Conditioner
A power supply impedance matching network is required for Fieldbus use.
This is referred to as a power conditioner. A power conditioner is a
Type 131 Non-I.S. Power supply intended for feeding and I.S. barrier. Output
voltage depends on barrier rating.
Type 132 Non-I.S. Power supply not intended for feeding and I.S. barrier.
Output voltage is 32 VDC Max.
Type 133 I.S. Power supply; complies with recommended I.S.
