Beckhoff KL1488 Bus Terminal

The Beckhoff KL1488 is an 8-channel digital input terminal designed for acquiring binary 24 V DC signals at the field level and transmitting them with electrical isolation to higher-level controllers. Its fast 3 ms input filter eliminates signal bounce from mechanical switches, ensuring accurate signal acquisition even in demanding environments.

Designed for space-saving applications using 1-wire ground switching, the KL1488 is ideal for multi-channel sensor connections where compact design and input precision are essential.
