PT-801 temperature controller is one of the new generation controllers with wide range of features and applications. It is designed for temperature measurements and controlling of the liquids and air.
PT-801 is a stationary device in housing resistant to humidity (IP-65).
The device has a large, graphic, backlit display, showing the temperature readout and the status of each relay simultaneously.
PT-801 cooperates with Pt-1000 resistor temperature sensor.
High measurement accuracy and stability have been ensured.
The signal from the sensor is amplified with use of pre-amplifier.
Thanks to the modern electronic components the controller’s memory has become fully independent from the power supply.
The device is easy to operate and has an English menu.
It is equipped with a collective optical signalisation of the correct work and the progress of the controlling process.
The controller is powered with standard 230V voltage, which is galvanically isolated from the input clamps. It is possible to use different power supply voltage: 110/230/24V AC, 12 – 24V DC. The device signalises low power supply level.

relays (alarm or PID regulation),
isolated digital: RS-485, MODBUS (ASCII and RTU);
isolated current outputs: 0 ÷ 20 or 4 ÷ 20 mA.
In case of using the relays and exceeding the entered lower or higher limits, the proper relay is switched (minimum and maximum alarm) or fill in or frequency coefficients are changed (for the PID controller).

The device is equipped with the real time clock with date.
It is possible to connect a remote panel (keyboard with display), which enables controlling the device from up to 1 km distance.
Possibility of the data radio transmission from the measuring head or sensor to the controller.
24 months of warranty, quick warranty and after warranty service.
The controller has a CE certificate.
