Description

With its dual-function keys and sharp display, OMEGAs RD8250 is a sophisticated process recorder. The graphic user interface makes configuration easy.

This recorder can display real-time data in digital or trend format. Via the front-panel USB port (order † œ-USB† option), the user can upload data from a flash memory card to a PC.

The RD8252 comes with an external AC adaptor with univeral plug set for 100 to 240 Vac 50/60 Hz. Other power options include 12 to 24 Vdc isolated input (RD8253), and a rechargeable battery pack option (RD8252-UPS). With the battery pack installed, the RD8252-UPS can function for up to 8 hours, preserving data and settings in the event of a power loss.
