KL1052
The KL1052 from Beckhoff features two inputs and 4-wire connection technology. Part of the KL Analog Input Modules, it operates at a nominal voltage of 24 V DC (-15%/+20%) and supports CE, UL, ATEX approvals. It offers a typical input filter time of 3.0 ms and K-bus current consumption of typ. 8 mA.
It operates between 0–55°C and provides a bit width of two inputs in the process image. The “0” signal voltage spans 7.6–17.4 V. The “1” signal voltage covers 0–7 V and 18–30 V.
