The Beckhoff KL3314 is a 4-channel analog input terminal designed for temperature measurement using thermocouples. Here are its key features:

• Supports multiple thermocouple types: J, K, L, B, E, N, R, S, T, U (default: type K).

• Measurement range: Defined per sensor type (default: type K; -100…+1370°C).

• Cold junction compensation: Internal temperature measurement ensures accuracy.

• Error detection: LEDs indicate broken wires.

• Resolution: 0.1°C per digit.

• Measurement error: < ±0.5% (relative to full scale value).

• Electrical isolation: 500 V (K-bus/signal voltage).

• Conversion time: ~250 ms.

• Compact design: 12 mm width, DIN rail mounting.

• Operating temperature: 0…55°C.

• Approvals: CE, CCC, UL, ATEX, IECEx, DNV GL.
