ABB PS700 1JNL100175-851: The Electrical Backbone of Your Control System
Description
The ABB PS700(Part number 1JNL100175-851)is a high-performance power supply module engineered for the ABB S800 I/O and AC800M control systems.It is the critical component responsible for converting incoming 24VDC to a stable and regulated power source for the entire I/O rack.
Application Scenarios
In a large-scale oil and gas facility,the stability of every piece of equipment is paramount.A sudden power fluctuation or failure could lead to catastrophic consequences,including process shutdowns,safety hazards,and massive financial losses.The field I/O modules,which connect the controller to the valves,sensors,and pumps,are the nervous system of the entire operation.Without a consistent and reliable power source,they are useless.The ABB PS700 module addresses this exact pain point.It’s more than just a power converter;it’s a protector.In critical applications,a redundant setup with two PS700 modules can be implemented.If one unit fails,the other seamlessly takes over,ensuring that the system’s”nervous system”never misses a beat.This capability provides engineers with peace of mind,knowing that the foundation of their automation system is secure and resilient against single-point power failures.

Technical Principles and Innovative Values
The ABB PS700 is designed with several key innovations that set it apart in the industrial power supply market.
Integrated Redundancy Management:The PS700 is not just a simple power supply;it’s specifically designed for parallel operation in a redundant configuration.This built-in redundancy capability allows for a hot-swappable setup where a failed unit can be replaced while the system remains online,ensuring zero downtime for critical processes.This is a game-changer for industries that cannot afford interruptions.
High-Efficiency Design:This module uses a highly efficient switching power supply topology.This means it generates less waste heat,making it ideal for use in compact,densely packed control cabinets where thermal management is a concern.The reduced heat also extends the lifespan of the module and other components in the cabinet,lowering long-term maintenance costs.
Advanced Diagnostic Capabilities:The PS700 features intelligent diagnostics beyond a simple”power on”light.Its LED indicators can clearly show operational status and fault conditions,such as overcurrent or reverse polarity.This intuitive feedback allows technicians to quickly identify the source of a power issue without complex tools or extensive troubleshooting,saving valuable time during a fault.
Application Cases and Industry Value
In a major petrochemical plant,the main safety instrumented system(SIS)relied on ABB AC800M controllers and S800 I/O modules.The plant’s management was concerned about the single-point-of-failure risk posed by the non-redundant power supplies.We proposed and installed a redundant power solution using two ABB PS700 modules on each critical I/O rack.The modules’hot-swappable capability allowed the installation to proceed without any interruption to the plant’s production.A few months later,a power surge from a nearby lightning strike caused a momentary fault in one of the PS700s.Thanks to the redundant setup,the second PS700 immediately took over,and the plant’s SIS remained fully operational.The faulty module was replaced in minutes without ever having to shut down the system.The plant reported that the investment in the redundant PS700 solution had not only mitigated their safety risk but had also provided an invaluable return on investment by preventing a costly unscheduled shutdown.

Installation,Maintenance,and Full-Cycle Support
Installation of the ABB PS700 is remarkably simple and efficient.The module is designed to mount directly onto a standard DIN rail,requiring no special tools.It then snaps into place on the corresponding terminal base(TB807),which handles all electrical connections.For redundant configurations,a second PS700 can be installed in parallel.This straightforward process minimizes installation time and potential for wiring errors.
Routine maintenance is minimal,primarily involving visual checks of the status LEDs to ensure proper operation.The robust design and built-in protection features mean that the module is highly resilient.In the event of a fault,the ABB PS700 can be hot-swapped in a redundant setup without disrupting the system’s power.This capability is invaluable for maintaining continuous operation.We offer expert technical support and a full-cycle service commitment,ensuring that from selection to installation and beyond,you have a reliable partner to keep your operations running smoothly.
