The SITRANS RD500 is an easy to use remote data manager that uses a web-based data application and hardware modules to provide integrated web access, alarm event handling, and data capture with worldwide access to instrument data log. It supports report and alarm notifications via email, SMS and FTP.
The RD500 can support up to 128 devices with flexible I/O modules and up to 247 Modbus serial devices with serial ports with an accuracy of ±0.1% of span for 8 channel, 4-20 mA.
The RD500 is made of high impact plastic and stainless steel and is Configured in a web-based interface so a standard browser is the only software needed for the system.
