Overview

ETS1701-100-000 is an electronic temperature switch from HYDAC's ETS 1700 series, designed for precise temperature monitoring and control of liquid media in hydraulic and lubrication systems. It is typically used in conjunction with the TFP 100 temperature probe, which is specifically developed for tank mounting.

The device features 4 independent relay outputs with changeover contacts, a 4-digit LED display, and a selectable analog output (4-20 mA or 0-10 V) for integration into monitoring systems. The switch points and reset points can be conveniently adjusted via the touch keyboard.

This model (ETS1701-100-000) specifically refers to the basic unit with 4 relay outputs and a measurement range of 0 to +100°C. The unit offers a high degree of flexibility with a 180° rotatable display and keyboard, allowing for optimal installation orientation.
