T287 Programmable Isolating Universal Input 2-Wire Transmitter
Brand: EurothermThe T287 is a programmable two-wire transmitter that is configured to provide an isolated 4-20 mA signal in proportion to the input signal.
The T287 accepts thermocouple, 2-wire, 3-wire, or 4-wire RTD, potentiometer, resistance and millivolt inputs.
The T287 supports either single or dual inputs. In the dual input mode, either input can be selected to control the output, or math functions can be applied in which both inputs have an effect on the output.
The functions available are Sum, Difference, Average, Higher of the two or Lower of the two inputs.
Typical applications include providing accurate, stable signals to distributed control systems (DCS), supervisory control and data acquisition systems (SCADA), environmental monitoring and control systems (EMCS), data acquisition and control systems (DACS) and custody transfer/pipeline systems.
