Beckhoff EL1809 Digital Input Terminal

The Beckhoff EL1809 is a 16-channel digital input terminal engineered to capture 24 V DC binary signals with exceptional noise immunity. Each channel operates via 1-wire connection technology, with an integrated 3 ms filter that suppresses contact bounce—ideal for mechanical switch applications.

With signal state LED indication, compact 12 mm width, and direct plug-in connection, the EL1809 provides an efficient, space-saving input solution for control cabinets requiring high-density wiring and robust electrical isolation from the field level.
