Beckhoff KL1418 Bus Terminal

The Beckhoff KL1418 is a high-speed 8-channel digital input terminal that acquires binary 24 V DC control signals from field-level devices and transmits them with electrical isolation to the higher-level controller. With an ultra-fast 0.2 ms input filter and EN 61131-2 Type 1/3 compatibility, it enables rapid and reliable signal processing for time-sensitive automation tasks.

Each channel features LED indication for real-time status monitoring, and its 1-wire connection system makes it ideal for compact, distributed I/O solutions.
