Here’s a concise breakdown of the Beckhoff KL3112 Bus Terminal:

• Functionality: A 2-channel analog input terminal designed for current signals in the range of 0–20 mA.

• Resolution: Provides 16-bit digitization (default is 15-bit) for precise measurement.

• Differential Inputs: Ensures electrical isolation and common internal ground potential.

• Error Detection: Identifies open lead or overload conditions and relays status via the K-bus.

• LED Indicators: Run LEDs show data exchange, while error LEDs indicate overload.

• Power Supply: Operates via the K-bus, consuming approximately 60 mA.

• Conversion Time: Default 140 ms, configurable down to 2 ms.

• Environmental Tolerance: Works within 0–55°C, with 95% relative humidity (non-condensing).

• Mounting & Protection: IP20-rated, designed for DIN rail installation.

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