The Mark* VIe Power Distribution Module (PDM) offers a set of inter-connectable products
to provide core system power for control electronics and I/Ocontact wetting and wiring
protection within the control system. When using GE’s power distribution parts, users
benefit from the following features:
• Automatic power monitoring and diagnostics to the controller, which alerts operations
and maintenance teams and eliminates manual programming and extra I/Ofor power
monitoring
• Proven power distribution scheme with coordinated fault protection and isolation
• Segregation of control and contact wetting power to avoid field wiring issues from
damaging control components
• Flexible redundancy schemes for most applications that support Dual or TMR options
• Simplified power schemes to reduce panel fabrication, assembly, and test time and
shorten the panel build phase of projects
PDM products include:
• IS410JPDx series of DIN-rail mountable PDMs distribute control power and I/O wetting
power within the control system
• Power Distribution Diagnostic Feedback I/Opack (IS420PPDAH1B) monitors control
and wetting power and branch fusing. The PPDA I/Opack is mounted on either the
IS410JPDGH1A or IS410JPDSG1A.
• Prefabricated power cable harnesses interconnect PDMs and system control and I/O
components
The Mark VIe control system can support two or more independent sources of power. A
typical configuration uses two separate AC grid power feeds as primary sources to bulk
control and wetting supplies. An optional secondary power source could be a plant’s
24, 48, or 125 V dc station battery system, which is charged by the local AC grid. This
configuration keeps the control system powered during loss of AC power events and
(with station battery) can support black start operations. The Mark VIe approach provides
flexible, field-proven redundancy schemes for the power sources, power supplies, and
power cables to Simplex and RedundantI/O, eliminates custom engineered solutions,
and assures proper responses to failures in power delivery. The application designer can
select the appropriate system reliability and fault coverage
