ABB YPP110 Low-Power LED Indicator Product Introduction

The ABB YPP110 is a compact,24 VDC panel-mounted pilot light module designed for visual indication of system status,alarms,or machine states in industrial control panels.Featuring a bright LED indicator with an integrated push-to-test button,the YPP110 allows operators to verify lamp functionality without activating the controlled process—enhancing safety and maintenance efficiency.It is commonly used with ABB AC 500 and AC 800M PLC systems,mounting directly onto compatible terminal bases(such as TB510,TB520,or TB540)to provide front-panel visibility for digital output signals.With low power consumption,long-life LED technology,and robust construction,the YPP110 delivers reliable human-machine feedback in harsh environments across power,water,packaging,and process industries.

Application Scenarios

At a municipal wastewater treatment plant in Scandinavia,operators struggled to confirm whether sludge pump commands were reaching field actuators due to lack of local feedback.The control system used ABB AC 500 PLCs,but the panel only showed HMI screens—no physical status indicators.Engineers installed ABB YPP110 pilot lights on the output terminals for each critical pump circuit,mounted on TB520 terminal bases.Now,a green YPP110 confirmed“pump enabled,”while red units signaled“fault active.”During a night shift blackout,maintenance used the push-to-test feature to quickly verify all lamps were functional before restoring power—avoiding misdiagnosis of a false alarm.The simple addition of YPP110 modules significantly improved operational transparency and troubleshooting speed.

Note:The YPP110 does not include its own wiring terminals—it requires a compatible ABB terminal base(sold separately)that connects to the PLC output and provides mechanical support.

Technical Principles and Innovative Values

Integrated Diagnostics:The push-to-test function eliminates guesswork during maintenance—no need to simulate a PLC output to check lamp health.

Space-Efficient Design:Shares the same footprint as standard signal terminals,avoiding bulky external pilot lights.

Low Load on PLC Outputs:Minimal current draw ensures compatibility even with sensitive solid-state outputs.

Color-Coded Clarity:Available in standard signal colors(red=alarm,green=run,yellow=warning)for intuitive operator interpretation.

Plug-and-Play Integration:No configuration or software setup—pure hardware-level status indication.

Application Cases and Industry Value

In a food packaging line using ABB AC 500 PLCs,frequent downtime occurred due to undetected jam faults.Operators couldn’t tell if a“conveyor fault”output was active because the only indication was buried in the HMI alarm list.By installing green YPP110 units labeled“Conveyor OK”next to each station—and wiring them to the inverse of the fault signal—operators gained instant visual confirmation.If the light went out,they knew a jam existed before product backed up.Mean time to repair(MTTR)dropped by 65%.The YPP110 turned abstract logic into actionable visual intelligence at minimal cost.

Installation,Maintenance,and Full-Cycle Support

Installation Steps:

Mount a compatible ABB terminal base(e.g.,TB520)on DIN rail.

Wire the PLC digital output(+)to the base’s input terminal and 0 VDC to common.

Snap the YPP110 onto the base until it clicks.

Label the lens per your functional requirement(e.g.,“PUMP RUNNING”).

Maintenance Tips:

Test monthly using the push-button to ensure LED illumination.

Replace if dim,flickering,or unresponsive—LEDs rarely fail but can degrade in high-temp environments.

Clean lens with dry cloth;avoid solvents that may cloud polycarbonate.
