The 392 from Eurotherm is a user configurable 1, 2, 3 or 4 pens continual trace, 100mm calibrated width circular chart instrument. Current status information is presented on a front panel mounted high visibility vacuum fluorescent display.

The compact design and modular construction ensure that is convenient to locate, while being easy to maintain, and upgrade. For greater flexibility the 392 can also be provided with two integral PID controllers.

User Configuration
Use of the integral keypad, and the structured parameter list allows for fast basic set-up and selection of those functions needed for a particular application. Configuration parameters are protected by a user definable password.

Display
The measured value for each channel is displayed along with, the channel number, engineering units, channel Descriptor and alarm information.

Integral Controllers
The model 392 offers two PID controllers with features such as cascade, ratio/bias, feed forward and internal setpoint generation. Dedicated auto/manual and remote/local setpoint keypads allow the user to switch between one control function to the other.

Features
Maths: Addition of the maths function allows for calculations ranging from simple add, subtract through to the more complex, Mass flow and Relative humidity.

Custom Curve: Allows for a user defined input, such as a Pirani Vacuum Gauge to be entered, as a series of point pairs, and selected for tracing on the recorder.

Totalizers: The 392 can be provided with up to 4 integrating/totalizing channels, with nine-digit resolution, for flow and power applications. Each totalizer channel is capable of driving a relay output, for example to drive an electromechanical counter.

Alarms: Up to four alarms can be configured per channel. Each alarm can be configured as absolute low/high, deviation, or rate of change.

Relays Outputs: Up to 8 relay outputs can be fitted, driven by any internal recorder event such as channel alarm, totalizer overflow, totalizer output.
