Description
The Chemelex RAYCHEM ACS-30-EU-VIA-DU-20-MOD Module for the ACS-30 system provides smart sensor input for surface snow melting and de-icing applications. The module provides
ground temperature and moisture sensing for the ACS-30 control system. The module can be positioned near to the heated area and is connected to the PCM module via a 3-wire cable. The
module is provided with a 15 m external ground temperature and moisture sensor to be positioned at the heated surface.
The output from the ACS-30-EU-VIA-DU-20-MOD module enables the switching of the heating circuits within the power & control module (PCM).
