flexotron ® 2000

Product catalog summary

Overview: The Flexotron® 2000 by Sauter Components includes the EXR 101 and EXR 102 switching units designed to enhance energy efficiency by enabling two-stage fan control. These units can be used for switching and alarm functions across various applications.

Key Features:

Analogue user interface for easy operation.
LED display indicating switching status.
Setpoint and switching difference settings available.

Technical Description:

Standard housing compliant with DIN 43880, made from flame-retardant thermoplastic.
Analogue input options: 0 - 10 V or 4 - 20 mA.
Potential-free relay contact per switch position.
Mountable on top-hat rail as per EN 60715.
Electrical connections via screw terminals for wires up to 2.5 mm².

Operation: The input signal is compared with setpoints XS1 (XS2). If exceeded, contacts 5-4 (8-7) close, indicated by an LED. If the input signal falls below XS1-XSd1 (XS2-XSd2), contacts 5-3 (8-6) close.
