Product Description:

The Beckhoff KL3312 is a highly accurate and unique analog input module that is used for measuring temperature with thermocouple sensors. This KL Analog Input Module has two input channels and is available for various types of thermocouples: J, K, L, B, E, N, R, S, T, and U. It is a 2-wire connection. It is designed for industrial use as it enables accurate measurements of the temperature. The process variable is by default set for Type K thermocouples with the measuring range of -100 degrees Celsius to +1370 degrees Celsius. Also, the KL3312 can provide both sub-microvolt (?V) as well as millivolt (mV) signals with the polarity of ~30 mV to ~120 mV.

Some of the important characteristics of the KL3312 include an LED display with 0.1 degrees C per digit accuracy, which ensures continuous and accurate power output. It also has a wiring fail indicator, which can be used to show connection issues, thus enhancing the security and efficiency of the wiring system. It has a conversion time of about 250 milliseconds, which is considered a fast and highly precise response. The KL3312 supplies power through the k-bus, so the wiring complication of the system is reduced. It is ideal to be used at temperatures of 0 degrees Celsius to 55 degrees Celsius, so it can be used in control cabinets and many other industries.

The construction of the KL3312 is durable, and it has approvals like CE, UL, ATEX, IECEx, and CCC. Therefore, it can be used in international processes. Due to the measurement accuracy that is less than ~ 0.5 percent full scale, the KL3312 module is reliable. This module is perfect for manufacturing, process control, and high-power systems.
