T280
Isolated Universal 2-Wire Transmitter for
Pt-100 RTD, Thermocouple, & mV
Miniature Thermal-Head Mounted,
1000VDC Input to Output Isolation
Universal Input Reduces Inventory Levels
Eliminates Ground Loops
Low Profile Design
Description
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.
The list of model numbers shows our most popular ranges. Contact
the Technical Services Group for information about other ranges.
