Industrial control systems often need to exchange analog current signals between devices that operate with different electrical characteristics. The ABB 1SVR011718R2500, identified as the CC-E I/I, is designed for this purpose by conditioning one current signal into another while maintaining electrical separation where required.
Instead of generating control logic or powering field equipment, this module acts as an intermediate interface within an analog measurement chain, helping connected instruments communicate with compatible current-loop inputs.

Signal Flow Example
The CC-E I/I is positioned between two devices that exchange analog current information.
| Source Device | Converter Function | Receiving Device |
|---|---|---|
| Pressure transmitter | Current signal conditioning | PLC analog input |
| Flow transmitter | Current conversion | DCS controller |
| Temperature transmitter | Signal matching | Monitoring equipment |
| Process instrument | Interface conversion | Recorder or indicator |
Its task is to ensure that the transmitted analog signal can be correctly interpreted by the receiving equipment.

Because several ABB interface modules have nearly identical housing dimensions, the complete article number should always be matched with the installed component.

Common Inventory Requirements
The CC-E I/I is regularly ordered for situations such as:
- Restoring analog measurement loops
- Replacing failed interface modules
- Expanding instrumentation panels
- Maintaining process control spare inventory
- Matching existing ABB interface hardware
Purchasing decisions are generally based on signal format compatibility rather than external appearance.
