KL3105X1-BA1 | Emerson DeltaV | I.S. Thermocouple/mV CHARM

Description

The Emerson KL3105X1-BA1 is an Intrinsically Safe (I.S.) Characterization Module (CHARM) designed for the DeltaV S-series system to interface with thermocouples and millivolt (mV) sensors. It provides high-accuracy temperature measurement for field devices located in hazardous areas by incorporating built-in galvanic isolation.

Features

• Built-in Cold Junction Compensation: Provides automatic compensation for thermocouple measurements, ensuring high accuracy without external sensors.
• Intrinsically Safe Interface: Specifically designed to limit energy levels for safe operation in Class 1 Div 1 or Zone 0/1 hazardous areas.
• Wide Sensor Compatibility: Supports a broad range of standard thermocouple types and low-voltage mV signals for diverse industrial applications.
• Electronic Marshalling: Integrates into the DeltaV S-series I/O structure, allowing individual channel assignment and reducing field cabinet complexity.
• G3 Environmental Hardening: Conformal coating protects internal electronics from corrosive gases and high-humidity environments.
• Mechanical Safety Keying: Utilizes the C5 terminal block position to prevent the accidental installation of non-thermocouple modules, protecting the sensor loops.
