 There
are several from M-System. However because these were spread out through
the plant the BVS is the best choice. The input (from the analyzer) comes
in through a dropping resistor (installed by M-System). The analyzer is
powering this loop. The output as shown on the schematic diagram (see the
Figure below) is powered externally (by the DCS). M-System shows a supply
voltage between 12-60V dc. This is referring to the supply powering the
output. Note the input is also isolated from the output. The BVS is a natural
cure for bucking power supplies. |

An
engineering company had specified an analyzer and a DCS system. During startup
they discovered that both devices were trying to power the loop. Additionally
the DCS was providing a common power supply for multiple loops.
