The new ET-9300 ice and snow detector is a single-channel basic device that can be used for all applications in the field of ice and snow detection. With the ET-9375 extension device, it can be expanded to multifunctional systems with up to 8 sensors/heating channels, and with the ET-9380 Internet module, it can be connected to the Internet either via LAN or WLAN. Operation and settings are carried out via an illuminated touch graphic display, which can also be used to parameterize the other devices in a system. The multilingual menu with 3-level password protection automatically adapts to the selected configuration (single device, gateway system or multi-channel system). In addition to the basic functions of the ice detection channel, the ET-9300 has zone management, with which the own channel and the ice detection channels of the extension devices can be centrally controlled via optional functions in up to 4 zones. A comprehensive alarm management checks both the internal device functions and those of the connected sensors. Furthermore, the function of the heating relay and a downstream contactor can be monitored. The control can be connected to a temperature and humidity sensor (ET-3356 or ET-3354), which are available separately. Measuring range -30 °C to °C, IP 20, load output max. 16 A, 230 V.
