Honeywell SPS5710 51198685-100 Power Supply Module

The Honeywell SPS5710 51198685-100, also cataloged as the SPS5710 Power Supply Module / System Power Supply, operates as a dedicated hardware component for regulated 24 VDC power delivery and high-availability distribution within Experion PKS platforms.

Hardware Specifications

Process Control and DCS Characteristics

• 4-20 mA HART loop protocol: The power infrastructure provides stable excitation voltages to support underlying measurement loops while maintaining loop integrity across distributed DCS nodes.
• FOUNDATION Fieldbus / Profibus PA connectivity: Clean regulated power distribution ensures reliable bus voltage maintenance for digital fieldbus communication networks.
• Channel-to-channel isolation: Internal circuit topology isolates output power stages from AC line fluctuations to prevent transient propagation into sensitive I/O electronics.
• Cold junction compensation (CJC): Auxiliary power rails supply stable reference voltages required by adjacent I/O modules executing precision temperature measurement and CJC algorithms.

Frequently Asked Questions

Q: Does the power supply module support hot-swapping during active system operation?

A: Yes. The module features a hot-swappable design that allows replacement within redundant 1+1 or N+1 parallel configurations without interrupting control system power.

Q: What protection features are integrated into the power supply architecture?

A: The unit incorporates integrated overvoltage, overcurrent, short-circuit, and overtemperature protections to safeguard downstream hardware.

Field Installation Guidelines

• Mount the module securely onto a standard industrial DIN rail or designated panel slot, ensuring adequate vertical clearance above and below the fanless natural convection chassis for thermal dissipation across the -40 deg C to 70 deg C operating range.
• Connect universal AC input wiring (100–240 VAC) to the primary terminals, verifying correct voltage range and phase matching before system energization.
• Route 24 VDC output power wiring separately from high-voltage switchgear paths and variable frequency drives to prevent electromagnetic interference and voltage drop.
• Ensure that the earth grounding terminal is securely bonded to the cabinet grounding bar to maintain proper surge suppression and EMC compliance.
