The Fuji Electric PXF4 temperature controller socket-type was designed as a successor to the PXR4 socket-type. It is geared with multiple input and output options as well as sophisticated control functions making it ideal for a wide range of applications. You can use any input among RTD, thermocouples, voltage, current, and mV. Switching the input is an easy parameter change. The socket terminal on the back makes this unit conveniently plug and play.
