Beckhoff KL1114 Digital Input Terminal

The Beckhoff KL1114 is a 4-channel digital input Bus Terminal designed to read binary 24 V DC control signals from the field and transmit them to higher-level automation systems. Featuring fast 0.2 ms input filters and full electrical isolation, the KL1114 offers reliable signal acquisition with low latency for time-critical applications.

Each input complies with EN 61131-2 type 1/3 specification and includes onboard sensor supply for simplified wiring. LED indicators provide real-time input signal status, making this compact module ideal for decentralized I/O systems.
