GE IS220PPDAH1A Power Distribution system feedback I/O pack
Description:
IS220PPDAH1A is part of GE Mark Vie series module. It is a Power Distribution system feedback I/O pack, the accessory is ISx0yJPDSG1A or IS40yJPDGH1A, can be used in hazardous site.
The Power Distribution System Feedback (PPDA) pack accepts inputs from up tosix different power distribution boards. It conditions the board feedback signals andprovides a dual redundant Ethernet interface to the controllers. PPDA feedbackis structured to be plug and play uses electronic IDs to determine the powerdistribution boards wired into it. This information is then used to populate theIONet output providing correct feedback from connected boards.
Voltage: min 27.4Vdc, nominal 28.0Vdc, max 28.6Vdc.
Current: Max 0.24Adc.
The Mark* VIe Power Distribution Module (PDM) offers a set of inter-connectable products to provide core system power for control electronics and I/O contact 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/O for 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
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 Redundant I/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.
