Overview
The Emerson DeltaV KL3105X1-BA1 is a precision Intrinsically Safe (I.S.) CHARM designed for DeltaV Electronic Marshalling systems. This module supports direct connection to temperature sensors and low-voltage signals in hazardous areas without requiring external I.S. barriers, simplifying installation while ensuring safety and measurement accuracy.
Key Features
Intrinsically Safe Integration
-
Integrated galvanic isolation meets IECEx ia and ATEX requirements for Zone 0 / Class I, Div 1 environments.
-
Eliminates external barrier cabinets, reducing wiring complexity and panel footprint.
-
Supports installation in Zone 2/Class I Div 2 environments.
Precision Measurement
-
Compatible with Thermocouple types B, E, J, K, N, R, S, T.
-
Accepts millivolt inputs from -100 mV to +100 mV.
-
Internal cold junction compensation ensures accurate temperature readings.
-
High-resolution ADC ensures stable and precise data acquisition.
Diagnostics and Reliability
-
Detects sensor faults, open circuits, and wiring issues.
-
LED indicators: Green (normal), Blinking Red (field fault), Solid Red (module fault).
-
Hot-swappable under appropriate hazardous area guidelines without interrupting other channels.

FAQ
Q: Can the module be removed while the system is powered?
A: No, the module must be inserted or removed only with system power off.
Q: Is calibration required for operation?
A: No calibration is needed; the module is factory-calibrated.
Q: Does the module support external I.S. barriers?
A: No external barriers are required; the CHARM provides built-in isolation and energy-limiting circuitry.
