The ET46 temperature controller is a direct replacement for the ET45 and is much smaller in size. The controller is housed in a 4 DIN module 70 x 88 x 62 mm enclosure. It comes with its own DIN rail mount or can be mounted on a standard 35mm DIN mounting rail. It has a number of new unique features including a universal power supply which enables the controller to operate on 240 or 24 Vac/dc. The power supply will operate over the range of 18 - 265V AC/DC.
