KL3314-0022 by Beckhoff

The KL3314-0022 from Beckhoff is part of the KL Analog Input Modules series and is engineered to deliver precise temperature measurements using a 4-channel configuration. This module is designed with a primary function for measuring temperature via various thermocouple sensor types, including the default type K setting, and offers an impressive measurement uncertainty of +-0.5% relative to full scale. It also provides a high resolution of 0.1° per digit, ensuring accurate and reliable data capture in industrial automation settings.

Technically, the module operates with a 2-wire connection method and utilizes a conversion time of approximately 250 ms to deliver updated readings quickly. It integrates 4 x 16 bit data inputs with an optional 8 bit control/status channel, underpinning its role in precise process monitoring. The device draws a typical current consumption of 75 mA from the K-bus and offers a flexible measuring range defined by the attached sensor, including millivolt measurements from -30 mV to +120 mV. These technical features ensure that the module meets the rigorous demands of modern industrial sensor applications.

In addition to its core functionalities, the KL3314-0022 is built for durability and ease of integration. Weighing approximately 75 g, it is suitable for standard DIN rail mounting and complies with EN 60715 standards. The module's compact dimensions, measuring 12 mm in width, 100 mm in height, and 68 mm in depth, make it ideal for space-conscious installations, while its vibration and shock resistance adhere to EN 60068-2-6 and EN 60068-2-27 standards. Safety is further enhanced by a built-in wiring fail indication and electrical isolation up to 500 V between the K-bus and signal voltage, making this module both reliable and efficient in demanding industrial applications.
