DDMC Analog Input Process Meter / Controller
Instruction Manual

Introduction

Front, back and in between, the DDMC meter boasts
specifications, features and functionality that make it
the only 1/8 DIN process meter you will ever need.
The number one feature that makes the DDMC such
a useful device is its built-in 24 VDC @ 200 mA power
supply to drive the transmitter. This feature not only
saves the cost of an external power supply, but also
greatly simplifies wiring. In addition, there is a second
24 VDC @ 40 mA power supply provided with the
4-20 mA output option.
Another reason why the DDMC Meter is the only
process meter you will ever need is its NEMA 4X
rated front panel. This means you can install the
DDMC in panels exposed to moisture, dust and other
adverse conditions. The next thing to notice is the 6-
digit dual-line display that can display numbers up to
999,999 on the upper line and show either a tag or
the input in a different scale on the lower line.
Other key features include four relays and 4-20 mA
output option, advanced input signal conditioning like
automatic round horizontal tank linearization, function
keys, pump alternation capability, and Modbus RTU
serial communications. Finally, all these features and
capabilities can easily be programmed with free
DDMC Meter View PC-based software.
