Here’s a concise breakdown of the KL3351 Bus Terminal from Beckhoff:

• Functionality: Single-channel analog input terminal designed for resistor bridge measurement.

• Measurement Precision: Digitizes bridge voltage (U D) and supply voltage (U REF) with 16-bit resolution.

• Voltage Range: U D: -16 mV to +16 mV, U REF: ±10 V (configurable).

• Technology: Supports strain gauge connection for precise measurements.

• Power Supply: Operates via K-bus, with an internal supply voltage of 5V DC.

• Conversion Time: Configurable, <250 ms.

• Error Margin: Measurement uncertainty < ±0.1% (relative to full-scale value).

• Environmental Tolerance: Works in 0°C to 55°C, storage range -25°C to +85°C.

• Installation: Mounts on 35 mm DIN rail, IP20-rated protection.

• Certifications: CE, CCC, UL, ATEX, IECEx approvals.
