SM – Smart Meter
The Smart Meter (SM) is described briefly here in a context of RMA installation only. For detailed
information on digital enhanced operating mode, display features, operation, and calibration, refer to
34-ST-25-08D SM 3000 Smart Meter User's Manual.
Function - The Smart Meter (SM) is a digital device that functions as an output and status indicator for a
compatible Honeywell Smartline Transmitter, or just as an output indicator for a non-Honeywell
transmitter operating in a 4 to 20 mA current loop. It can operate in the analog mode (4-20 mA), or can
operate in the Honeywell proprietary Digital Enhanced (DE) mode.
Application - The SM can be used as a Remote Meter Assemblies component with any one of the
following Smartline Transmitters.
• ST 3000 TM
Smart Pressure Transmitter
TM
• STT 3000
• MagneW 3000
As indicated in the illustration, the SM is similar in appearance to the DM. That is, they both have a multi-
segment fan-style bargraph that indicates from 0% to 100%, and both include status indicators. However,
the SM can be easily distinguished from the DM in that the SM has:
•
17-segment bargraph (compared to 25 for the DM)
•
more status indicators than the DM
•
three wire connections (Red, Blue, and Yellow) to other components whereas the DM has two wire
connections (Red and Yellow).
•
The SM has a configuration button on the periphery of the case at lower left
Electrical Characteristics - The SM is a current-oriented device that is connected in series with the
transmitter via the Yellow and Blue wires. The Red wire carries virtually no current; its purpose is to
provide a digital communication signal voltage for the meter. In non-hazardous locations, the RMA 3000
can include more than one SM, and can be used in combination with the ME (analog meter). For more
information, refer to the paragraphs under the heading Multiple Remote Meters.
DM – Digital Enhanced Meter
The Digital Enhanced Meter (DM) is described briefly here only in the context of RMA 3000 application
and installation. For detailed information such as DE operating mode, display features, operation, and
calibration, refer to
34-ST-25-07A DE 3000 Smart Meter User's Manual.
Function - The Digital Enhanced Meter (DM) functions as an output and status indicator for a compatible
Honeywell Smartline Transmitter operating in the DE mode only; that is, it cannot be used in the analog
mode as can the SM.
