Isolating amplifier for type K thermocouples

Today arrived two of modules of the ones shown in image down below.
Those are sealed isolating amplifiers for thermocouple type K temperature sensors.
Every module has mounted four ISOT10-D-K amplifiers.

In future I’ll design a little pcb/or protoype pcb with four adc channels to do temperature monitoring of up to four channels.
Technically possible would be up to eight channels but right now I see no need for it.
