The current loop relays are designed to integrate with sensors, displays, and other components that work under the same 4-20 mA loop. They provide food, establish slogans and show the translated values to the units of each process.

· Control a range of current of 4..20 mA DC between the adjusted margins. When conditions are right, the relay is activated and it deactivates when the current is shifted out of these margins.
· The models are distinguished by combinations of the following characteristics:
- Control 1, 2 or 3 set points.
- Fixed or adjustable hysteresis.
- Timing detection, fixed or adjustable.
- Display of measured values.
