Interface and Signal Details

The KL3031X1-BA1 connects field RTD leads to the carrier backplane through dedicated slot contacts. Each module handles one sensor channel and digitizes the resistance value internally. Therefore, technicians gain stable readings without external transmitters or signal conditioners. The unit seats in a standard carrier slot and draws power from the shared rail.

Physical and Environmental Parameters

The module measures roughly 140 mm by 88 mm by 25 mm and weighs about 0.18 kg. Its slim housing supports dense channel counts inside compact carriers. Meanwhile, the 0°C to 60°C operating range suits most control room environments. The on-board energy storage stabilizes excitation current and filters measurement noise.

Why This Module Matters

Plant teams value the KL3031X1-BA1 for its accurate temperature sensing and compact footprint. The filtering capacitors keep readings steady during electrical interference events. As a result, process control stays tight and calibration intervals extend. Technicians also appreciate the clear channel marking and quick slot replacement.
