The analog Solar Irradiance Sensor Si-13TC was enhanced to the Si-13TC-ISO. The Si-13TC-ISO has galvanic isolation between power supply and the analog output. Therefore the Si-13TC-ISO is ideal for use with SOLARCHECK of Phoenix Control.
Additional to the irradiance sensor we have ambient and module temperature sensor with galvanic isolation. These sensor come along with a rugged alumium case and 3 m cable and are well prepared for hard industrial environment.
