Omega OMA-VM500-4 is a seven-channel 4-20ma sensor monitor and autodialer, designed to assist in process measurement and control. With its advanced capabilities, it offers real-time monitoring, alarm notifications, and customizable settings for various applications.

The OMA-VM500-4 allows you to monitor up to seven sensors simultaneously, providing comprehensive data collection and analysis. It can convert 4-20mA signals into sensor-specific measurements, such as degrees, PSI, or Lbs, enabling easy interpretation and reporting.

One of its key features is the auto-dialer function. When a sensor goes into an alarm condition, the device automatically calls up to four programmable voice or pager numbers. This ensures timely notification and allows for immediate response to critical events.
