Emerson Ovation 1X01047H01L1 DCS Power Supply Module

Configured for stable power distribution in Ovation Distributed Control System platforms, the Emerson 1X01047H01L1 (1X01047H01L1 Power Supply Module) provides direct physical/electrical execution. This module integrates into cabinet assemblies to deliver regulated DC potential to adjacent controller architectures and local I/O nodes. Utilizing integrated MOSFET switching architecture, the unit minimizes active thermal generation while maintaining consistent voltage output across variable internal backplane load demands.

Hardware Specifications

Channel-to-Channel Isolation & Backplane Power Distribution

The power supply module operates with high-efficiency MOSFET circuitry to reduce thermal dissipation inside dense control enclosures. Internal power routing provides galvanic isolation between input mains and output DC rails, preventing transient noise propagation into sensitive logic circuits. When deployed in redundant configurations, the unit coordinates with external ORing modules or internal decoupling circuits to enable parallel power sharing. Consequently, the power supply maintains regulated 24 VDC rails without introducing voltage drops across the system backplane during single-supply failover events.

Frequently Asked Questions

Q: What power output parameters does the 1X01047H01L1 supply to downstream modules?

A: The module supplies a regulated 24 VDC output with a nominal current capacity of 20 A, delivering up to 480 W of total continuous power to system backplanes and field devices.

Q: How does the unit maintain thermal stability in high-density enclosure deployments?

A: The unit utilizes solid-state MOSFET switching topology to minimize passive heat dissipation, allowing stable continuous operation across ambient enclosure temperatures ranging from -40 to +85 deg C.

Q: Can the 1X01047H01L1 be configured for redundant power operation?

A: Yes, the module supports both standalone and parallel redundant operation when integrated with compatible external decoupling redundancy modules or dedicated backplane power buses.

Field Installation Guidelines

Ensure power leads are completely de-energized before attaching the unit to the T-type DIN rail. Position the module vertically to allow unimpeded natural convection through the top and bottom ventilation slots. Maintain a minimum clearance of 50 mm above and below the housing to prevent thermal buildup within the cabinet.

Secure input and output field wiring to the screw terminals using recommended wire gauge specifications. Route DC output cables separately from high-voltage AC lines to eliminate inductive noise coupling. Connect the primary earth grounding terminal directly to the central cabinet ground busbar using a short, low-impedance copper conductor. Verify terminal connection torque settings prior to applying primary AC line voltage.
