Description
The ABB 1SVR011714R1100 is a single-function standard analog signal converter from ABB’s CC-E series, designed to provide precise current-to-current signal conditioning with full three-way electrical isolation . This compact DIN-rail mount module accepts a 0–20 mA input signal and delivers an identical 0–20 mA output, ensuring clean, isolated transmission of analog process signals in industrial automation environments .
Engineered for integration into PLC, DCS, and instrumentation systems, the ABB 1SVR011714R1100 addresses the critical pain point of ground loop interference and signal degradation in long-field wiring applications. Its 3-way isolation architecture separates input, output, and power supply circuits, eliminating potential differences that corrupt analog measurements and ensuring reliable data acquisition from sensors and transmitters. With a fast response time of just 0.2 ms and a compact 22.5 mm width, this module delivers high-performance signal conditioning without consuming valuable cabinet space .
Application Scenarios
Imagine a large chemical processing plant where a pH transmitter located 150 meters from the control room has been producing erratic readings, causing unnecessary control loop oscillations and product quality excursions. The maintenance team has verified the transmitter’s calibration and checked the wiring—yet the PLC input still shows fluctuating values due to induced noise from nearby VFD cables and ground potential differences between the field instrumentation and the control cabinet.
By installing the ABB 1SVR011714R1100 in the control cabinet, just before the PLC analog input card, the field signal passes through the module’s 3-way isolation barrier. The green LED indicator confirms the 24 V DC supply is present, and the clean 0–20 mA output now faithfully represents the actual pH value without the superimposed noise . Within hours, the control loop stabilizes, and product quality returns to specification. The plant’s instrumentation engineer notes that the 1SVR011714R1100 “solved in one shift what weeks of troubleshooting couldn’t,” underscoring how targeted signal conditioning protects critical control logic from electrical interference in large industrial installations.

Technical Principles and Innovative Values
Innovation Point 1: Three-Way Galvanic Isolation for Signal Integrity
The core innovation of the ABB 1SVR011714R1100 is its full three-way isolation architecture, which electrically separates the input circuit, output circuit, and power supply. This eliminates ground loops and common-mode voltages that frequently corrupt analog signals in industrial installations where field instrumentation and control equipment operate on different electrical references. The isolation ensures that the signal reaching the PLC or DCS is an accurate representation of the field value, independent of potential differences that would otherwise introduce errors .
Innovation Point 2: Ultra-Fast 0.2 ms Response Time
With a response time of 0.2 ms, the ABB 1SVR011714R1100 is capable of faithfully reproducing rapidly changing process variables without introducing significant phase lag . This performance is critical in fast-loop control applications such as flow regulation, pressure control, and motion systems where signal delay degrades control stability. Many competing signal conditioners offer response times measured in tens of milliseconds, making the 1SVR011714R1100 a superior choice for dynamic applications.
Innovation Point 3: Compact 22.5 mm DIN-Rail Package
The ABB 1SVR011714R1100 packs full isolation and conditioning functionality into a 22.5 mm wide housing, enabling dense panel layouts . This space-efficient design allows control engineers to install multiple conversion channels in a small cabinet footprint without sacrificing electrical performance or isolation integrity. The module’s slim profile also simplifies retrofitting into existing panels where space is at a premium.
Innovation Point 4: Visual Health Monitoring via Green LED
The integrated green LED provides immediate visual confirmation that the 24 V DC supply voltage is present and the module is operational . This simple diagnostic feature allows technicians to quickly verify the module’s status during routine walkthroughs or troubleshooting, eliminating the need to connect a multimeter to confirm supply presence—a small but practical detail that accelerates field service and reduces mean time to repair.
