D7300 Modbus TCP/IP Ethernet Thermocouple Input Module


The D7300 thermocouple input module contains seven differential inputs for measuring thermocouple temperature sensors.  Eight different thermocouple sensors can be measured, including types J, K, T, E, R, S, B and C.  Each input channel can be programmed to measure any one of eight types.

The module performs all signal conditioning, cold junction compensation, a 16-bit analog to digital conversion, linearization and stores the temperature result in a 16-bit unsigned integer format. The unsigned integer values represent a percentage of the full scale temperature range.

The data values are transmitted to any supervisory host computer that supports the Modbus TCP ethernet protocol.  See the links to a Modbus scaling example and product documentation below.
