Product Description:

This KL3312-0010 terminal bus is a versatile two-channel analog input module by Beckhoff designed for precise temperature measurement using thermocouple sensors. Beckhoff company never fails to introduce and design high performance equipment that is found proficient in various industrial automation setups.

This KL3312-0010 terminal bus supports various thermocouple types including J, K, L, B, E, N, R, S, T, and U, with type K set as the default. The device offers a wide measuring range from -100°C to +1370°C for type K sensors and is capable of millivolt measurements in the range of ±30 mV to ±120 mV. With a resolution of 0.1°C per digit. It consists of a conversion time as 250 milliseconds and delivers highly accurate and responsive temperature data. This KL input series device holds 500 V electrical isolation between the K-bus and signal voltage which helps in ensuring safe operation in different environments. It has built-in wiring fail indication and offers less than ±0.5% measurement uncertainty relative to the full scale by making it reliable for critical temperature monitoring tasks. The stripping length for wiring is 8-9 mm with a maximum current load on power contacts of 10 A.

This KL3312-0010 terminal bus thermocouple module weighs just 70 grams and is designed to fit on a standard 35 mm DIN rail mounting category. Its polycarbonate housing provides protection as IP65 while side-by-side mounting is enabled by a double slot and key connection system. The unit operates within a temperature range of 0 to +55°C and complies with multiple industry standards by including CE, UL, ATEX, and IECEx. Its configuration is straightforward as there is no need for address setting with all adjustments made via the Bus Coupler or controller.
