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.
