1. The assembly of power board BM125

1.1. Features
(1) Access to two AC220V power sources, providing redundancy of power supply for the entire cabinet.
(2) Distribute the redundant DC24V power for the CPU, IO module, 24V network switches, optical interface.
(3) Provide AC220V power sources for Network switch(AC220).
(4)Monitor the total 24V power in the cabinet and provide contact output(normally closed).

2. The assembly of power board BM125-DEH

2.1. Feature
The power component is special for project DEH. The main function is to allocate the power 24V, the power
DC220V, the power AC220V.
(1) Access to two AC220V power sources, providing redundancy of power supply for the entire cabinet.
(2) Distribute the redundant DC24V power for the CPU, IO module, 24V network switches, optical interface.
(3) The component distribute power for up to three servo walves—two for servo valve and the other for
redundancy.
(4) The component distribute power for OPC in the cabinet ,ETS’s DC220V.
(5) The component of RELAY can choice powered by AC220V or DC220V,both are distributed by BM125-
DEH.
(6) The component can also access the two external input DC220V,the component export the power after
redundancy.
(7) The component design of alarming,shutting down the whole component when the power lossed.monitoring
the energized state of the double power of 24V for the servo valve,DPU,IO module,network switcher.
