Product Description:
The KL3222 Bus Terminal by Beckhoff is a compact high precision module designed for accurate temperature measurement in industrial automation settings. It is compatible with various temperature sensors like Pt100, Pt500 and Ni100. The model enables precise monitoring through its 4-wire connection technology and supports a wide temperature measuring range.
The KL3222 bus terminal features two inputs and operates via the K-bus with a conversion time of approximately 50 ms. The unit supports several types of sensors including Pt100, Pt200, Pt500, Pt1000, Ni100, Ni120 and Ni1000. It can measure resistance in the range of 10 Ω to 1.2/5 kΩ and also accommodates KTY resistance thermometers. Its wide measuring range spans from – 200 °C to + 850 °C for Pt sensors and – 60 °C to + 250 °C for Ni sensors with high precision up to – 320 °C. The typical measurement current is 0.5 mA and the device features a resolution of 0.01 °C per digit. The error margin at 40 °C ambient temperature is about 0.1 °C. It operates with open circuit recognition and provides robust electrical isolation of up to 500 V.
The module has a typical K-bus current consumption of 60 mA that makes it energy efficient while offering a bit width of 2 x 16 bit data for process integration. It supports easy configuration via the Bus Coupler or controller without needing address settings. The model is housed in a durable polycarbonate body with a compact design of 12 mm width, 100 mm height and 68 mm depth. It complies with several industrial standards including EMC and vibration resistance and has a protection rating of IP20. It functions in temperatures ranging from 0 °C to 55 °C with a relative humidity of up to 95 %.
