TELEVAC MX Active Gauge EthernetIP Gateway

Part Number: 2-8900-100

The MX Active Gauge EthernetIP Gateway is the first and only solution designed to provide an EthernetIP connection between Televac active vacuum gauges and Rockwell Automation® Allen-Bradley® PLCs. An increasingly popular industrial network communication standard, EthernetIP communication offers users faster and more reliable vacuum measurements and eliminates the need for additional analog-to-digital converters.

Gateway Compatible Vacuum Gauges

The gateway supports an easily configurable network of up to (4) Televac active vacuum gauges and (1) capacitance diaphragm vacuum gauge (CDG) through EthernetIP communications. Multiple gateways can also be daisy-chained together for additional vacuum gauge connections (made possible by dual EthernetIP ports on the back of the unit). The gateway allows users to interface directly with supported PLCs and PCs, including the ability to acquire vacuum measurements and adjust vacuum gauge settings from a convenient, remote location without complicated conversion tools. In addition to Televac vacuum gauges, the gateway supports CDGs from MKS, Inficon, Leybold, Brooks, and Setra. 24 V DC and ±15 V DC with D-sub 15 (DB15) and D-sub 9 (DB9) connectors are supported.

Using the Gateway for Heat Treat and Vacuum Furnace Applications

The gateway is particularly useful for heat treat and vacuum furnace applications where a single gateway can eliminate the need for up to (5) analog-to-digital converter (ADC) input channels while simultaneously removing any latency from analog-to-digital conversions (causing a mismatch between the vacuum gauge display and the furnace human-machine-interface or HMI), along with giving the end user the ability to calibrate their vacuum gauges from their HMI. This means no more climbing on top of your furnace to do vacuum measurement comparisons! The ability to change settings and calibrate digitally is due to the unique design of the gateway, where all communication with Televac vacuum gauges is done digitally (via RS-485).

More Information and Similar Products

Essentially you can think of the gateway as a fancy RS-485 to EthernetIP converter. The exception to this is the CDG input, which takes the 0 to 10 V DC analog output of the CDG and converts it to a digital value (using an analog-to-digital converter) which can then be read over EthernetIP.
