Notes:
Thermocouple inputs are cold-junction compensated and reported as °F or °C.
These specifications apply to ET-8INS modules manufactured afterJuly 30, 2004. Performance characteristics of earlier modules may be different. Consult the factory for more information.
The default analog input integration time for this module is 100 mS per channel. This mode is recommended for all applications where moderate noise filtering is desirable.
Specifications are subject to change. Consult the factory for the latest information.
