ADTECH TCX226 4-20 mA Wire Transmitter 8-42 VDC

ADTECH TCX226 is a two‑wire, isolated thermocouple transmitter that converts a thermocouple input into a 4‑20 mA current loop, powered from 8 to 42 VDC. It provides galvanic isolation between input and output, making it suitable for connecting temperature sensors in noisy industrial environments without ground loops. The transmitter accepts standard thermocouples (B, E, J, K, N, R, S, T) with ISA calibration and input spans from -20 mV to +100 mV, enabling precise temperature measurement across common process ranges. A variant, the TCX226‑H27, is listed with a NEMA 4 enclosure for rugged, dust- and water‑resistant service while maintaining the 8–42 VDC supply and 4‑20 mA output, making it well suited for harsh industrial installations.
