Ion Multi Gauge Controller MG14



The MG14 Multi Gauge Controller is a dual gauge controller. The first channel can support any B-A gauge and any Extractor gauge. The second channel supports any commercially available gauge based on the 0-10V output standard*. As standard, all of Oerlikon-Leybold gauges are supported: ITR 100, ITR 90, DI 200, DI 2000, TTR 211 S, TTR 91, PTR 225. Any others can be implemented as an option. Although just 1U height, the controller is able to display both channels at the same time on the large alphanumeric LCD display. The high brightness blue display provides clear readout from large viewing angles and long distances. A unique feature of the MG13 is the availability of 4 interlocks, each of which can be separately programmed for each channel, including threshold levels and hysteresis. The measurement channels are active immediately upon power-up and ready for emission. Channel 1 is a dedicated channel for B-A gauges. It features very flexible B-A gauge parameter settings and is therefore suitable for use with almost all commercially available third party B-A gauges. The controller is perfectly suited for 2 stage pumps group units, where two ranges (low and high vacuum) need to be controlled.

The unit is also fully software controlled and web-enabled so that it can be operated over any network, including the internet.

*** Only one comms interface can be used at any one time and is chosen at time of order. However, this may be swapped/interchanged with any other comms interface at any future date via simple rear panel plug and play swap, without having to access the internals of the unit.

**** please refer to manual

Only one communication interface can be chosen at time of order (please refer to table) but this can be easily changed in the future via simple rear panel plugin connection modules, without ever having to access the internals of the unit.
