D5300M Modbus Thermocouple Input Modules

$275.00

The D5300M Modbus thermocouple input modules measure four thermocouples of the same type. Thermocouple types include J, K, T, E types.

The D5300M Modbus thermocouple input modules provide an isolated 15-bit measurement, analog to digital conversion and a linearization of the digital data. The digital data values are scaled in 16-bit unsigned integer data format that represents a percentage of full scale. See the Modbus scaling example link below.

The digital data values are transmitted to a host computer using the Modbus RTU serial protocol via an RS-232 or RS-485 serial connection. The D5000M series supports up to 247 Modbus RTU devices on one RS-485 serial port. Since Modbus protocol does not support RS-232 echoing, D5000M series modules cannot be daisy-chained. This limits you to one module per RS-232 serial port.

Modbus Scaling Overview

Thermocouple Measurement Ranges:
J= -200 to +760 C
K= -150 to +1250 C
T= -200 to +400 C
E= -100 to +1000 C

 

The D5300M Modbus thermocouple input modules can be mounted on a DIN-rail using the MK-1 mounting kit.
