Product Description:

The KL3314-0012 Analog Input Modules is produced by Beckhoff. It is a four-channel input module intended for thermocouple signals. It guarantees accurate temperature measurements with a small design suitable for industrial applications. This belongs to the series of the KL Analog Input Modules.

The Beckhoff ‘s KL3314-0012 can handle thermocouple types J, K (default), L, B, E, N, R, S, T, and U. It also supports direct mV measurement between ±30 mV and ±120 mV. It has a measurement range for type K from -100 to +1370°C. Its two-wire technology provides a simple and dependable connection mechanism. The resolution is 0.1°C per digit that results in extremely detailed temperature measurements. The K-bus and signal voltage are isolated at 500 V electrically. It consumes 75 mA of current from the K bus. This Input Modules has a conversion time of around 250 ms which allows for efficient data gathering. To improve reliability the module has a wiring failure alert system Input data is 4 × 16-bit with optional 4 × 8-bit control or status information. The Bus Coupler or controller manages configuration without requiring an address. Storage temperature ranges from -25°C to +85°C and the operational temperature ranges from 0°C to 55°C.

The Beckhoff's KL3314-0012 has an IP20 protection certification. The compact housing made of polycarbonate material ensures durability and optimal space utilization. It can be attached onto a 35mm DIN rail (EN 60715) with a lock system. Side by side mounting is facilitated by the double slot and key connection. The KL3314-0012 can withstand power contact current loads of up to 10 A. It has a capacity to endure up to 95% relative humidity without condensation. This module offers safety and simple integration into complicated control systems.
