Thermocouple to RS485 Modbus converter DAT3018

General Description

The Thermocouple to Modbus converter DAT3018 Modbus is an 8 Channel Thermocouple Modbus converter. The DAT3018 RS485 Modbus converts J, K, R, S, B, E, T, N, Type Thermocouples to a 16 bit digital format. The DAT3018 also converters 25 mV, 100 mV 250 mV and up to 1 V to a Modbus RS485 signal. The data is transmitted by the Modbus protocol on RS-485. The DAT3018 Modbus is also available in the RS323 ASCII format.
