ENDRESS + Hauser has launched a number of derivatives of the robust industry standard Eco-Graph paperless recorder that combines increased functionality with environmental compatibility at a competitive price, and with no running costs in replacing paper and pens.
The Eco-Graph features three or six channel universal analog inputs with two alarm set points per channel, four control/event inputs and three freely configurable output relays as well as RS232 and RS485 communication protocols.
Each universal input can accept 0-20mA, 4-20mA, all standard voltages, RTDs and thermocouples. Additionally the three channel version can be ordered with a further three loop powering channels with HART communication.
The Eco-Graph can also be configured to integrate the analog inputs on each of the six channels to display and log totalised values.
The unit's large 5" (127mm) colour graphic display can be programmed to show alarm setpoints and events (eg power failures, alarm conditions, etc), event messages and additional channel information such as tag numbers, engineering units, etc.
A quick set-up function and automatic signal detection simplifies the configuration process. This automatic signal detection function not only reduces set-up time but also makes sensor replacement easier.
The set-up process is menu-driven, activated via the front panel buttons and complemented by an intuitive built-in operating manual. The operator simply selects the measurement type and the engineering unit required and then sets the scaling.
Set-up can also be executed using the ReadWin operating software, which is included with the Eco-graph at no cost. Channel parameters can be quickly copied to other channels and channel configuration downloaded using the Eco-Graph's internal diskette drive.
ReadWin also allows the user to dial-in remotely from a GSM or analog modem, giving access to real-time values, and the ability to download archived data.
The unit offers a fully adjustable feed rate from 5mm/h to 1000mm/h and stores the equivalent of up to 89m of paper worth of data in its 2Mb internal memory.
The Eco-Graph monitors the amount of storage memory available and alerts the user when the memory or diskette approaches the full level. Endress + Hauser 02 8877 7000.
