OM-240 is a versatile, high accuracy “smart” data acquisition system. It provides 24 differential analog inputs, individually configured. The Data Logger can be used in a wide range of applications, including HVAC, oil and gas, water quality, energy and building monitoring. Using OM-240 requires no additional configuration/analysis software package, as it is provided by an Embedded Web Server. Only a standard Web Browser (Firefox recommended) for configurations and data view. Logged Data is ready to be shown in a graphic “real time” mode (License required) or exported in a CSV file. Channel expansion provided by multiplexers. There are 8 terminal blocks (each terminal block can handle up to 3 sensors). The OM-240 is designed to work with 2 to 6-wire sensors. You can connect 2-wire sensors on each channel and read 24 sensors, or 4-wire sensor and read 12 channels. The system will order sensors depending on how many wires they use, placing 6 wires sensors first, 4 wires in the middle, and 2 wires last.
Once software configuration is done, clicking on “Wiring scheme” button on the web interface near the sensors will show how to connect the chosen sensor to the block physically. It shows “relative” position, so if you start connecting sensors from the first, you will not have to leave “unused” positions (except for the ground connection of every block, if not used). Multiplexers are needed if the total “wires” from sensors exceeds the 48 provided by the OM-240.
Applications including Oil/Gas Pipeline Monitoring, Building/Bridge Structure Health Monitoring, Engine Thermal Mapping Testing, Data Center Environmental Monitoring, and Energy Farm Monitoring, and etc.

Do the Expansion modules allow thermocouple readings?
Hi Ken, thank you for your question. Yes, the multiplexer allows thermocouple inputs.

This is a similar model with less channels as 8, 12, 16 or 20?
We will require more information to help on this question, please email the DAS team at DAS@OMEGA.COM

Is OM-240 compatible with Endress + Hauser TMR35?
Thank you for your question. We will require more information to help on this question, please email the DAS team at DAS@OMEGA.COM

How many channels can you add to the base unit? I have a machine that is around 54. Adding the expansion unit would give me 48.
Thank you for your question .Expandable Up to 384 Channels with Multiplexers

Does the OM-240 work with PX51 model pressure transducers, or only PT100/200/500/1000?
Thank you for your question. The OM-240 will be suited for a variety of different sensors like the PX51 which has a dc voltage or current output.

How can the OM-240 be configured to display temperatures in °F instead of °C? If it can, please explain how this is done. I have been unable to convert Engineering Units from °C to °F.
Thank you for your question. We will require more information to help on this question, please email the DAS team at DAS@dwyeromega.com

Can I acquire data from five analog sensors at one second interval (all sensors to be read at the same instant)? With one data sample consisting of time and readings from five sensors, how may data samples can be stored in the internal memory? Thanks
Thank you for your question. We will require more information to help on this question, please email the DAS team at DAS@OMEGA.COM”
