Description

The RDM is a remote display device designed to communicate with the FCS Flexible Control System controllers. It displays gas readings, channel status and faults received from the FCS and can be viewed from a remote, relevant location such as a refrigeration application where there are two different entrances to the chiller room. The RDM employs connection loss detection to ensure the information that is displayed is current. Simple configurations such as adjusting the display contrast and setting the Modbus ID and baud rate can be done in the field. The RDM has several display configurations such as: show/not show one or more channels of interest, readings displayed by line scrolling or page scrolling, display one type of gas and not another, display only the top 4 channels in high alarm, etc. The RDM comes in a standard water / dust tight, corrosion resistant ABS / polycarbonate enclosure with a hinged, secured door.

Available with an optional, factory installed side mounted strobe with audible (Option -L2).

The RDM used to be called the QCC-RDM. Product Notification
