Beckhoff KL1002 2-Channel Digital Input Bus Terminal 24V DC

The Beckhoff KL1002 is a compact 2-channel digital input Bus Terminal designed to acquire binary control signals from field devices and transmit them with electrical isolation to the higher-level automation system. Operating at 24 V DC with a standard 3 ms input filter delay, this Beckhoff I/O module is ideal for interfacing with mechanical limit switches, proximity sensors, pushbuttons, and binary sensors across Beckhoff Bus Coupler systems (including K-bus, EtherCAT BK/EK series, and fieldbus networks).
