AP4351 Field Configurable Isolator

Brand: Eurotherm
Does not ship to United States

The AP4351 isolating thermocouple conditioner offers wide ranging input and output capability. 

The AP4351 can be field configured by the user to accept input from thermocouple types J, K, T, R, S, E, and B and to provide current or voltage output. 

The output is linearized to temperature according to the particular thermocouple type.

The AP4351 is a three-port industrial isolator the output is optically isolated from the input up to 1,500 V, and both input and output are transformer isolated from the line power.
