ABB CC-E I/I 1SVR011718R2500 Signal Converter

Electrical Isolation: 3-way galvanic isolation between input, output, and power supply circuits (up to 1.5 kV AC test voltage)

Accuracy/Linearity: High transmission accuracy with error limits typically under +/-0.1% of full scale

Response Time: Fast internal signal conversion settling times (typically under 10 ms)

Temperature Coefficient: Low thermal drift design (typically within +/-200 ppm/°C) to maintain stability in warm enclosures

Mounting Footprint: Ultra-slim 22.5 mm wide housing configured for standard 35mm DIN-rail snapping

Connection Terminals: Screw connection blocks for secure, vibration-proof field wiring termination

Industrial Sectors:

Process Automation and Control, Chemical and Petrochemical Processing, Water and Wastewater Treatment Utilities, Power Generation and Distribution, Factory Automation, and HVAC Infrastructure.

Application Scenarios:

1. Signal Isolation and Ground Loop Elimination: Inserted into an analog loop between a field-mounted transmitter and a central PLC/DCS input card to break ground loops, suppress electrical noise, and prevent stray voltages from damaging expensive control system components.

2. Long-Distance Signal Boosting: Deployed in sprawling production environments to refresh and regenerate a degrading 4-20 mA current loop signal over long wire runs, maintaining signal integrity and accuracy back to the control room.

3. PLC/DCS Channel Protection: Acts as a sacrificial interface barrier; if a field line gets shorted or hit by a voltage surge, the inexpensive CC-E converter fails while completely safeguarding the multi-channel main controller hardware.

4. Signal Distribution and Decoupling: Used to duplicate a single 4-20 mA transmitter signal into a secondary isolated loop, allowing an auxiliary local display panel to monitor process values simultaneously without interfering with the primary automation processor loop.
