Emerson KL3106X1-LS1 I.S. Thermocouple Input CHARM Module

Product Description

The KL3106X1-LS1 from Emerson is a single-channel analog input CHARM module engineered for thermocouple signals in DeltaV systems. Its intrinsically safe (I.S.) design ensures secure operation in hazardous environments, including Zone 2 and Class I Division 2 locations.

Featuring LS1 keyed terminals, this module prevents miswiring and simplifies installation. The compact CHARM format allows seamless integration into DeltaV racks while maintaining a minimal CHARM bus power draw. With broad environmental tolerance and robust resistance to shock, vibration, and airborne contaminants, it provides reliable temperature measurement in industrial conditions.
