KL1722
The KL1722 is a 2-channel analog input module from Beckhoff's KL Analog Input Modules. It features 2-wire connection technology and operates at 120/230 V AC with 2 inputs handling signal voltages of 0 to 40 V and 79 to 260 V. A typ. 10 ms input filter and > 3 mA (typ. 6 mA) input current ensure stable processing. With ohmic/capacitive input behavior and IP20 protection, it's ideal for industrial automation.
