The Ziehl range of digital temperature relays offer an array of temperature protection relays for us with a standard PTC and PT100 sensors. They are used in applications which require accurate protection against the damaging effects of heat. Suitable for use in transformer protection, motor protection, winding protection and temperature monitoring in process applications.
The range offers devices from 1 to 12 sensor inputs, with a selection of outputs- analogue, digital and Ethernet enabled.
Several of the relays are available with intrinsically safe approval for use in hazardous environments. With ATEX approval the relays are approved or use in area where combustible gases need temperature monitoring (marking G: gas) or in areas with combustible dust (marking D: dust) require temperature monitoring and protection.
There is an option for wireless temperature monitoring of High-voltage Transformers
The range is available in Panel or DIN rail mounting with or without a digital display. Ziehl also manufacture a range of PTC sensor for use with the relays.
