** 4 Channel Vacuum Gauge Interface - VGI-100 **

The VGI-100 is primarily targeted for use in the high and ultra-high vacuum industry.

The unit is designed to provide an interface to between up to four high vacuum gauges and provides an RS485 output suitable for transmitting over long distances (anything up to 1 km). The VGI-100 is supplied complete with Windows PC compatible software for displaying the measured vacuum gauge readings.

The VGI-100 can also be supplied with an RS232 compatible port.

The vacuum gauges (see below for list of supported gauges) are connected using RJ45 sockets along the top edge of the VGI-100. This allows the direct connection of many industrial standard vacuum gauges. The connections support control of the digital gauge enable or degas input where required.

The RS485 or RS232 interface together with the +24Vdc power supply required to power the gauges are connected via standard pluggable screw connectors.

Using a dll it is possible to interface the VGI-100 to most Windows software. Full details of the serial port protocol are available.

The VGI-100 is also supported by the Cigol Controls VCP-800

The VGI-100 is symmetrical DIN rail mounting (you can see the "release clip" in the picture above).
