FOUNDATION Power Supply/Conditioner
The Fieldbus Power Supply types 9412 are used for simple or redundant
supply and signal conditioning of FOUNDATION fieldbus H1 segments.
With high output power of up to 28 V and 500 mA it is possible to use a
large number of devices on even long distances. For special applications
with very high power requirements, two parallel Fieldbus Power Supplies
in Boost-Mode can supply up to 1A current.
Three different voltage output versions designed for FNICO/FISCO-ic,
Entity/nL/ic and High Power Trunk applications are available.
During operation the fieldbus segments are continuously monitored for
overload and short circuit. All FPS variants comprise a powerful
physical layer diagnosis unit which is able to monitor all parameters.
These can be read via the serial interface connection on the front and
any PC. Online diagnosis is featured by an optional Diagnosis
Communication Module (DCM) via several communication protocols.
Type 9412/00-320 monitors the physical layer parameters with adjustable
alarming values, signaling contact, and a 5-level LED group.
The Fieldbus Power Supplies can be installed as single units on DIN-Rail
or in system specific bus-Carriers Series 9419.
