394 circular chart recorder with annotation is a clear leader in circular trending technology. It combines four color printing with annotation to produce a clear and easy to read chart. The 394 can monitor up to 6 simultaneous inputs.
The recorder is fully configurable from the front panel or via the optional PC card reader.
Up to two independent controllers can be added enabling the 394 to control as well as record the process. Modbus communications make this instrument a very flexible component in a system or network solution.
20 Character vacuum fluorescent display
The 394 status display consists of a 20-character vacuum fluorescent display and alarm indicators.
PID control
Two independent controllers (Eurotherm Type 2216) can be case mounted to provide PID control of related process variables.
User configuration
The recorder is fully configurable from the front panel using pushbutton keys to follow a series of text prompts at the display. Access to most functions can be password protected. The recorder can also be
configured from a PC based package, allowing the user to set up the configuration off-site for later downloading to the recorder.
Modbus RTU communications
The communications option uses the Modbus RTU protocol to ensure compatibility with standard SCADA software and other types of industrial equipment. The EIA485 (RS485) specification allows multiple instruments on a single communications link.
