Analog Devices 3B47-J-03 Thermocouple Input Module

Analog Devices 3B47-J-03 is a single‑channel isolated, linearized thermocouple input module that conditions a thermocouple signal for direct interface with standard high‑level analog I/O subsystems. It accepts thermocouple types J, K, T, E, R, S, and B, and provides amplification, linearization, and filtering of the input signal while preserving galvanic isolation between input and output to protect the measurement system from ground loops and field‑transient disturbances. The conditioned signal is converted to a high‑level analog output suitable for connection to PLCs, data‑acquisition hardware, or other process‑control instrumentation. The 3B47 family supports configurable input/output ranges, enabling tailored measurements, and the J‑type variant is identified by the -J suffix.
