Fieldbus Power Supply Series 9412

For FOUNDATION fieldbus^TM H1 acc. to IEC 61158-2
High power output up to 350 mA
Installation in Zone 2, Division 2 or in the safe area
Isolation between fieldbus segment and the input power supplies
Error message for power or bus failure via relay contact
LED indicators for simple diagnostics
Integrated fieldbus terminator

Type 9412/PS-I, 9412/PS-2

Redundant power and fieldbus supply for high availibility applications
Simple module replacement without fieldbus reset

Type 9412/PS-DT, 9412/PS-D

Redundant power connection
Dual channel fieldbus

The Fieldbus Power Supplies 9412/PS-I and 9412/PS-2 are used for the redundant supply and signal conditioning of none intrinsically safe FF H1 fieldbusses. The system consists of a carrier with two supply modules that can be exchanged in operation.

The Fieldbus Power Supplies 9412/PS-D and 9412/PS-DT are used for the supply and signal conditioning of up to two none intrinsically safe FF H1 fieldbusses. The system consists of a carrier with two supply modules.

The versions 9412/PS-I and 9412/PS-DT already includes the terminator for the fieldbus segment.

The fieldbus circuit and the supply for the Fieldbus Power Supply are monitored. If the voltage drops the required level an error message via a relay contact (normally closed) follows.

The units can be installed also in Zone 2 and Div. 2. For easy installation up to 8 Fieldbus Power Supplies (9412/PS-I and 9412/PS-2) or up to 5 dual Fieldbus Power Supplies (9412/PS-D and 9412/PS-DT) can be cascaded. All terminals are exchangeable.
