Electronic hygrostat - EFL 012
EFL
The electronic hygrostat measures the surrounding relative humidity and can switch a signal current via its internal relay with a potential-free change-over contact. Signal-processing devices can be controlled directly with the EFL 012. In order to control heating and cooling equipment, filter fans and signal devices the switch module SM 010 or a similar device is needed.
The LED integrated in the adjustment knob shows the closed status of the contact 1-2. When relative humidity drops contact 1-2 opens and the LED turns off. In currentless state (no supply voltage) contact 1-2 opens.
- Large setting range
- Small hysteresis
- Optical operating display (LED)
- Change-over contact
- Signal application
