'20' Series Temperature Controllers

VT9620

With the introduction of the '20' series of digital temperature controllers, Fast Heat brings quality digital temperature controllers within the reach of most applications. Each of the three controllers in the range offers heat and cool output channels plus two independant alarm outputs. Auto Tune is provided as standard as is the ability to run in manual mode with the user selecting the output power.

All the '20' Series controllers are now available for operation from a 24V supply for intrinsically safe control panels.
