  • Universal Input Reduces Inventory Levels
  • Eliminates Ground Loops
  • Low Profile Design
  • Hinged Cover Protects Potentiometers from the Environment
  • Embedded Terminals


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 100mV. 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.

Three different series make up the T280 family. The -1xxx units are for Pt-100 RTD inputs. The default configuration from the factory is 3-wire, but the units can be easily reconfigured for 2-wire, as explained in the installation instructions. The -2xxx units are for thermocouple inputs and the -3xxx units are for millivolt inputs.
