GENERAL DESCRIPTION
The D5000M series are similar to the D5000 series but
use the Modbus RTU protocol for communication. The
modules convert four analog input signals to engineering
units and transmit in ASCII format to any host with stan-
dard RS-485 or RS-232 ports. These modules can
measure temperature, voltage and current. The modules
provide direct connection to a wide variety of sensors and
perform all signal conditioning, scaling, linearization and
conversion to engineering units.
The modules contain no pots or switches to be set.
Features such as address, baud rate, parity, echo, and
scaling are selectable using simple commands over the
communications port—without requiring access to the
module. The selections are stored in nonvolatile
EEPROM which maintains data even after power is
removed.
