    The Beckhoff KL1408 is an 8-channel digital input terminal designed for 24 V DC signal acquisition in modular Bus Terminal systems. It captures binary control signals from the process level and transmits them electrically isolated to the higher-level automation unit. Each channel includes an LED indicator for signal status. Its compact 12 mm housing and single-wire connection technology simplify wiring and save space in control cabinets.
