Product Description

The product of Beckhoff as KL3202-0021 is a highly versatile analog 2 channel input bus terminal which is designed for proper temperature readings in industrial automation applications. Beckhoff company mainly offers products as controllers, software, and I/O systems to help machines to process tasks efficiently by improving performance and productivity in various sectors.

This KL3202-0021 terminal bus contains a wide range of resistance temperature detectors (RTDs) such as Pt100, Pt200, Pt500, Pt1000, Ni100, Ni120, and Ni1000 sensors. Its capability to handle different sensor types makes it suitable for diverse temperature monitoring needs. It even covers a measuring range of -200°C to +850°C for Pt sensors and -60°C to +250°C for Ni sensors. This KL input series terminal bus compact structure is designed for I/O systems with power supplied via the K-bus and no additional power contacts required. The terminal operates with a typical measuring current of 0.5 mA and delivers a resolution of 0.1°C per digit. This feature helps in ensuring highly accurate readings. The conversion time is approximately 250 ms which strikes a good balance between speed and precision for most industrial processes. It offers an uncertainty of less than ±1°C by making it a reliable option for sensitive temperature reading.

This KL3202-0021 terminal bus features out another key aspect as its open-circuit recognition which helps ensure consistent performance and decreases chance of error while working. It also meets high safety and quality standards, with electrical isolation up to 500 V and compliance with international regulations such as CE, UL, ATEX, and IECEx certifications. Its IP20-rated polycarbonate housing, compact design, and vibration resistance make it suitable for toxic industrial environments and its compatibility with a wide variety of wiring setups simplifies installation.
