Emerson VE5132 DeltaV Bulk Power Supply Redundancy Module

The Emerson VE5132, also cataloged as the VE5132 Power Supply Redundancy Module, operates as a dedicated hardware component for decoupling and monitoring parallel bulk power sources within DeltaV distributed control system platforms.

Hardware Specifications

Process Control & Power Interfacing

The VE5132 module manages redundant bulk power configurations to prevent single-source failures from disrupting system power.

• Dual Input Decoupling: Employs high-current decoupling diodes to isolate two independent 12-28 VDC power supplies, preventing a short circuit on one input line from pulling down the active output bus.
• Galvanic Diagnostic Isolation: The internal diagnostic monitor circuit is isolated from the main power path, routing system fault signals safely to DCS controller input channels via a dry contact relay rated for low-voltage signaling.
• Conformal Coating Protection: Standard industrial conformal coating safeguards internal copper traces and surface-mount components from moisture-induced leakage currents and chemical degradation in harsh Class G3 environments.

Frequently Asked Questions

Q: Does the VE5132 module regulate or boost the output voltage?

A: No. The VE5132 is a passive diode-or redundancy module. The output voltage directly tracks the input voltage, minus a nominal silicon diode forward voltage drop (typically 0.5 to 0.8 VDC depending on the load current).

Q: What is the maximum current limit supported on each individual input terminal?

A: Each input path (Input 1 and Input 2) is designed to handle up to 20 A continuously. To achieve the full 40 A rating at the output terminal, both inputs must be powered by separate, load-sharing bulk supplies.

Field Installation Guidelines

• Power Conductor Termination: Secure all high-current input and output wires to the heavy-duty screw terminals, ensuring a tightening torque of 0.8 N-m (7 in-lb) to prevent loose, high-resistance connections.
• DIN-Rail Earthing Verification: Ground the module's metal housing directly through its integrated DIN-rail clamping clip, verifying that the rail is bonded to the primary cabinet ground bus.
• Thermal Management spacing: Maintain a minimum clear distance of 40 mm (1.5 in) on the left and right sides, and 80 mm (3.1 in) above and below the module to allow sufficient airflow for passive convective heat dissipation.
