Product Description:

The Beckhoff KL3311-0000 is a high-performance thermocouple input module that is used to measure temperature in industrial applications. It belongs to the KL series of Beckhoff and can be used for simple and precise temperature measurement. This module has one input channel and is supplied with high power through the K-bus, which allows it to be connected to other Beckhoff modules quickly and easily. It is well suited for industrial systems, wherever it is necessary to keep the temperature at a certain level or to monitor the temperature of some equipment during production processes.

The KL3311 module is compatible with popular thermocouple sensor types such as type J, K, L, B, E, N, R, S, T, and U. The default type of the sensor is Type K, which is used widely in different industries. It can also measure millivolt (mV) signals, which makes it versatile for many applications, especially by distinguishing between high and low voltage circuits. The measuring range of type K thermocouples is -100 degrees C to +1370 degrees C. This makes the module capable of functioning at low as well as high temperatures with a high level of precision.

It has multiple safety and quality approvals, including CE, CCC, UL, ATEX, and IECEx. These certifications ensure that it can be safely adopted in different countries and in areas that are considered hazardous. The KL3311-0000 is convenient to use, has no moving parts, and offers consistent speed under low loads with accurate control of temperature. It can be effectively used by engineers working on automation systems where data related to temperature needs to be monitored accurately. This module is valuable for controlling or maintaining ovens, motors, or climate conditions to facilitate the safety and execution of an industrial system.
