T280 Isolated Universal 2-Wire Transmitter

Brand: Eurotherm
Does not ship to United States

The T280 is an isolated, 2-wire temperature and mV input transmitter designed to fit in a standard industrial thermal-head.

The T280 supports Pt-100 RTD and thermocouple inputs as well as voltages up to 100 mV.

Thermocouples supported include B, E, J, K, L, N, R, S and T.

If thermal-head mounting is not required, the T280 can either be mounted directly on a bulkhead or to a DIN rail using the included DIN rail clip.
