Emerson KL3106X1-BA1 | I.S. Thermocouple Input CHARM

Product Description

The KL3106X1-BA1 is an intrinsically safe (I.S.) analog input CHARM module from Emerson, specifically designed for thermocouple signal acquisition in DeltaV systems. It allows precise and reliable temperature measurement in hazardous areas while maintaining compliance with global safety standards.

This compact CHARM module integrates directly into DeltaV racks, providing single-channel thermocouple input with low CHARM bus power consumption. The terminal block key position BA1 ensures correct wiring and installation, while the rugged design withstands vibration, shock, and airborne contaminants. No calibration is required, and the module has no user-serviceable parts, making it maintenance-free.
