The PXR series comes in several sizes - 1/32 DIN, 1/16 DIN, 1/8 DIN and 1/4 DIN. Besides the standard features including auto-tuning and fuzzy logic, they also come with self-tuning. This innovative feature automatically retunes the controller under certain conditions without the need to revert to auto-tuning.

The standard 8-segment ramp/soak feature has been expanded to include two patterns that can be linked to create a 16 step profile. The

that is watertight and corrosion resistant. The easy to use 3 button keypad allows easy programming. The rear screw terminal makes connection easy and eliminates the cost of extra sockets. The PXR3 (1/32 DIN) can be DIN rail mounted with an optional adapter.

Remote monitoring of up to 31 controllers at a time is possible with the RS485 option that uses the industry standard Modbus protocol. The communications option comes with our free Windowsbased software PXR-LITE which allows programming the controller from the PC and viewing realtime data and a trend graph while logging data into a text file.

The ETTR is a programmable temperature relay with the ability to act as an ON/OFF temperature controller. The device is capable of fully stand alone operation, but may be monitored and programmed with the custom software and a serial RS232 interface.

The Programmable Temperature Relay ETTR may be programmed in two control modes: (a) temperature range mode in which it will turn ON the output relay between two defined temperatures and (b) set point mode in which it will turn ON below a defined temperature and OFF above a defined temperature. The span between the temperatures may be adjusted to customize the hysteresis. The Programmable Temperature Relay ETTR may also be placed in a manual mode of operation in which the relay is controlled via the GUI software.
