Tag: 1SVR011718R2500

Description:

The ABB 1SVR011718R2500 is a plug-in auxiliary contact module designed exclusively for the ABB TA25DU series of thermal overload relays.As a standardized signal interface component,it delivers two normally open(2NO)contacts and integrated dual-color LED indication—enabling real-time visual feedback and seamless integration into PLC or DCS control systems without additional wiring.

Compact yet critical,this module transforms passive motor protection devices into intelligent,communicative nodes within modern automation architectures—enhancing diagnostics,reducing downtime,and simplifying panel design.

Application Scenarios:

At a major municipal wastewater treatment plant in Germany,engineers struggled with frequent unplanned pump shutdowns due to undetected thermal trips.Operators had to manually inspect dozens of motor starters inside cramped MCC rooms—delaying response by hours.After retrofitting all TA25DU relays with the ABB 1SVR011718R2500,each pump’s status became instantly visible via green(healthy)or red(tripped)LEDs on the front of the cabinet.Simultaneously,the 2NO contacts fed real-time signals into the plant’s Siemens PLC,triggering automated alerts and work orders.The result?A 60%reduction in mean time to repair(MTTR)and zero repeat failures from missed overloads.In this context,the 1SVR011718R2500 proved not just a spare part—but a force multiplier for operational visibility.

Technical Principles and Innovative Values:

Innovation Point 1:Mechanical-to-Visual Signal Conversion–Unlike electronic monitoring modules,the 1SVR011718R2500 uses direct mechanical linkage from the TA25DU trip mechanism to drive both contacts and LEDs.This eliminates external power needs,firmware updates,or communication protocols—ensuring fail-safe indication even during total control system blackouts.

Innovation Point 2:Zero-Wiring Integration–By snapping directly onto the relay body,the 1SVR011718R2500 eliminates field wiring for status signals.This reduces installation errors,saves up to 15 minutes per motor starter,and minimizes terminal block clutter in dense MCC layouts.

Innovation Point 3:Dual-Use Contact Flexibility–The two independent NO contacts allow one to feed a local alarm light while the other connects to a remote PLC input—supporting both on-site and centralized monitoring without signal splitters or relays.

Innovation Point 4:Maintenance Transparency–The bright,high-contrast LED is visible from 3 meters away under typical plant lighting,enabling rapid fault localization across entire motor control centers—critical in emergency response scenarios.

Application Cases and Industry Value:

In a Tier-1 automotive stamping facility in Michigan,over 200 hydraulic presses relied on ABB TA25DU relays for motor protection.However,production losses mounted due to“ghost stops”—unexplained halts traced later to unnoticed thermal trips.After installing ABB 1SVR011718R2500 modules across all lines,maintenance teams gained immediate visual confirmation of trip events.Combined with PLC integration,the plant implemented predictive maintenance rules:if a motor tripped twice in one shift,it triggered an automatic inspection ticket.Within six months,unplanned downtime dropped by 42%,and motor rewind costs fell by$180,000 annually.Users praised the 1SVR011718R2500 for its“set-and-forget reliability”and“instant clarity under pressure.”

Installation,Maintenance,and Full-Cycle Support:

Installing the ABB 1SVR011718R2500 requires no tools or wiring—simply align the module over the TA25DU relay and press down until it clicks into place.Ensure the base relay is in the reset position before installation to avoid mechanical interference.The module operates reliably in ambient temperatures from-25°C to+60°C and is rated for industrial environments with moderate dust and vibration(IP20 when installed in an enclosure).No calibration or configuration is needed;it functions purely through electromechanical linkage,ensuring decades of maintenance-free service.

For replacements,the 1SVR011718R2500 can be swapped in seconds during routine maintenance—without de-energizing the main motor circuit.Fault diagnosis is intuitive:if the LED doesn’t illuminate when the relay is energized,either the TA25DU mechanism is damaged or the module has failed.Given its solid-state-free design,failure rates are exceptionally low.We maintain global inventory of genuine ABB 1SVR011718R2500 units,all factory-new and tested for contact continuity,LED function,and mechanical fit.Every unit comes with a 12-month warranty and full technical documentation.Our engineering team provides 24/7 support for integration queries,compatibility checks,and bulk deployment planning.
