Overview The Beckhoff KL3102 is a 2-channel differential analog input Bus Terminal for −10…+10 V signals. It digitizes voltage with 16‑bit resolution and transmits it galvanically isolated to the controller. LEDs indicate data exchange with the Bus Coupler. Filter and conversion time are configurable for performance/accuracy trade‑off. Key Features Two differential analog voltage inputs (±10 V) 16‑bit resolution (for 0…10 V range: 15‑bit) Default conversion time 140 ms; configurable down to 2 ms 50 Hz input filter (configurable) Input impedance > 200 kΩ; common‑mode voltage up to 35 V Electrical isolation: 500 V (K‑bus/signal) Specifications Specific MPN KL3102 Inputs 2 channels, differential Signal Voltage Range −10…+10 V Resolution 16 bit (0…10 V range: 15 bit) Conversion Time 140 ms default; configurable down to 2 ms Input Filter 50 Hz (configurable) Input Impedance > 200 kΩ Common‑Mode Voltage max. 35 V Accuracy < ±0.3% of full scale K‑bus Current typ. 65 mA Process Image 2 × 16‑bit data (optional 2 × 8‑bit control/status) Dimensions (W × H × D) 12 × 100 × 68 mm; IP20
