What's New - 73VR2100 Paperless Recorder

Model 73VR2100 series is a 5.5-inch TFT LCD recorder for 2-, 4- and 6-point universal input. Sampled data are stored in a CF Card and monitored locally on the screen or at the host PC via Ethernet.

Universal Input
The 73VR2100 can accept either 2, 4 or 6 points of universal input (See Table 1). All analog input channels are isolated between each other thanks to the input circuit composed of multiplexing optical relay and floating ADC, which is designed so that no only a single optical relay turns on at one time.

A versatile input types and ranges are available as shown in Table 2.

TFT LCD Display
The 5.5-inch TFT LCD display is not only clearer and larger compared from the 4.7-inch STN LCD used with the 73VR3000, but has a wider viewing angle.

In addition to the conventional white chart color, a new blue-to-black gradating background color is selectable.

Compact Size
The 73VR2100, despite of the larger LCD display, still fits into DIN standard 144 mm square panel cutout. Furthermore, thanks to its high-density circuit board design, its depth is only 172 mm, approx. 20% shallower than typical paperless recorders, without sacrificing its isolation performance and easy-to-use screw terminal block. The 73VR2100 can easily replace an existing small-size paper recorder.

High Speed 100 ms Storing Mode
The 73VR2100 can sample and store at the maximum of 4-point DC voltage inputs in 100 millisecond intervals, including not only in the normal recording control but also the remote trigger recording mode.

Calculation Functions
12 channels are available for ‘Function’ pens. One calculated result can be used for another calculation, and sampled and calculated data from a previous cycle can be used for next calculation. By these additional features, accumulation or rate-of-change functions for analog signals are now possible.

Alarm trip can be programmed for calculated results.

Accumulated values can be reset by a timer or an external trigger contact input.

Other Features Inherited from the 73VR3000
CF card hot-swapping, operation lockout (password) function, IP 65 front panel and many other standard features from the 73VR3000 are also inherited by the 73VR2100 series.
