Beckhoff KL1498 Digital Input Terminal

The Beckhoff KL1498 is an 8-channel digital input Bus Terminal designed to acquire binary 24 V DC signals via ground switching and transmit them to higher-level control systems with full electrical isolation. Optimized for fast switching applications, the KL1498 features a rapid 0.2 ms input filter and supports direct connection of multi-channel sensors using space-efficient 1-wire technology.

Each input shares the 24 V power contact as its reference and includes individual LED indicators for quick diagnostics. This module is ideal for space-constrained automation setups requiring high-density digital input interfacing.
