2D34347G06 is an upgraded rack plug-in switching power supply under Emerson Westinghouse 2D34347 series for Ovation DCS control system. It serves as the updated substitute model of 2D34347G05 and can be directly interchanged with other same-series variants including G07 and G08. This module provides steady 24VDC power to rack controllers, digital and analog I/O cards as well as internal cabinet relay circuits in thermal power, nuclear power and petrochemical automation control cabinets.

The unit supports N+1 redundant parallel connection and field hot swap maintenance, ensuring the whole rack will not lose power due to breakdown of a single power module. It adopts fully enclosed metal housing with built-in heat dissipation structure. Multiple LED lamps on front panel separately indicate AC input status, normal DC output and equipment fault alert. Internal optimized EMI filter and enhanced multi-stage surge suppression components effectively resist electromagnetic disturbance generated by cabinet contactors and frequency converters. The product meets UL, CE and IEC industrial safety and EMC specifications and is available for long-term 24-hour continuous running.

The power supply accepts universal wide AC input ranging from 85VAC to 264VAC with working frequency between 47Hz and 63Hz to adapt various industrial power grids worldwide. It outputs stabilized 24VDC, with upgraded internal circuit compared to G05 version for lower output ripple and more stable performance under alternating full load and light load working conditions.

Complete protective mechanisms consist of overvoltage protection, overcurrent protection, automatic cutoff against output short circuit and thermal shutdown protection. The module will immediately terminate output once overload, short circuit or overheating occurs so as to avoid damage to subsequent DCS control hardware.

Normal operating temperature inside control cabinet is from 0 degree Celsius to 60 degree Celsius, while storage temperature ranges from minus 40 degree Celsius to positive 85 degree Celsius. Applicable working relative humidity keeps between 5 percent and 95 percent with no condensation formed inside the module.

All models of 2D34347 series including G05, G06, G07 and G08 share consistent mounting size, terminal layout and pin assignment for direct plug-and-play replacement on original rack slots. This series has different outer dimension and interface definition against 2B10335, 2B10715 and 2D34069 power supply series and cannot be cross replaced mutually.

This power module is widely equipped in Ovation DCS cabinets for boiler main control, steam turbine ETS protection cabinet, auxiliary equipment interlock control, nuclear auxiliary control system and petrochemical SIS emergency shutdown system to provide reliable power supply for core control boards and field signal acquisition modules.

2D34347G06 belongs to Emerson Westinghouse Ovation DCS 2D34347 series rack plug-in power supply, an upgraded replacement model for 2D34347G05. It delivers regulated 24VDC power to rack controllers, analog and digital I/O modules and internal cabinet relay circuits in thermal power, nuclear power and petrochemical control cabinets. The module supports N+1 redundant parallel configuration and on-site hot swap, preventing full rack power failure from single unit fault.

It is constructed with sealed metal casing and integrated heat dissipation structure. Front panel is fitted with LED indicators for input power, normal output and fault alarm respectively. Upgraded EMI filter and multi-level surge suppression circuits are built inside to withstand strong electromagnetic interference from cabinet contactors and frequency converters. The product complies with UL, CE and IEC industrial EMC and safety standards and allows nonstop 24-hour long time operation.

Wide alternating current input ranges from 85VAC to 264VAC at 47Hz to 63Hz to match different industrial power grid standards globally. The output is stabilized 24VDC; compared with G05 version, internal circuit components are optimized for smaller output ripple and more stable performance under frequent load variation between full load and light load.

Integrated protection functions cover overvoltage protection, overcurrent protection, automatic short-circuit shutdown and overheat cut-off protection. Output will be cut off rapidly once overload, short circuit or overheating happens to protect downstream DCS hardware.

Operating temperature inside control cabinet is 0℃ to 60℃, storage temperature is from -40℃ to 85℃, and applicable working relative humidity is 5% to 95% without condensation.

All variants of 2D34347 series including G05, G06, G07 and G08 have identical installation dimension and wiring definition for direct plug and play interchange. This series differs in outline and pin layout from 2B10335, 2B10715 and 2D34069 power supply series and cannot be cross-installed for substitution.

It is commonly used in Ovation DCS cabinets for boiler main control, steam turbine ETS protection, auxiliary equipment interlock system, nuclear auxiliary control and petrochemical SIS emergency shutdown system as stable power source for control and signal collection modules.
