Beckhoff KL1498 is an 8-channel digital input terminal for 24 V DC sensors, employing negative (ground) switching to register active signals on the bus terminal system. Specifically, it provides eight independent 24 V DC inputs with a fast typical response time of 0.2 ms per channel. Part of the KL1xxx family, KL1498 integrates into Beckhoff's Bus Terminal architecture, enabling straightforward connection of field devices to a PLC or industrial controller. Used in automation to monitor sensors such as limit switches and proximity sensors in 24 V DC ecosystems, this device supports electrically isolated signals to the controller.
