The Beckhoff KL1104 Digital Input Terminal is a compact and efficient solution for integrating binary control signals from the process level into your automation system. This four-channel input terminal is designed to capture signals in an electrically isolated form, ensuring reliable and secure communication with the higher-level control unit.
Engineered for space-saving installation within control cabinets, the KL1104 boasts a narrow design with a width of just 15mm when connected. It is equipped with input filters that provide a response time of 3 ms, making it suitable for a wide range of industrial applications where speed and precision are paramount.
The terminal operates on a nominal voltage of 24 V DC, with a permissible range that accommodates minor fluctuations in power supply. It is designed to recognise a "0" signal voltage from -3 V to +5 V and a "1" signal voltage from 15 V to 30 V, ensuring versatility in various operating conditions. Each channel's status is conveniently indicated by light-emitting diodes, allowing for quick visual diagnostics.
With a typical input current of 5 mA and a similar current consumption from the K-bus, the KL1104 is an energy-efficient addition to your system. It also features electrical isolation of 500 V between the K-Bus and field potential, enhancing the safety and integrity of your operations.
The terminal is built to withstand a wide range of environmental conditions, with an operational temperature range of -25°C to +60°C and storage temperatures from -40°C to +85°C. It also conforms to stringent vibration and shock resistance standards, ensuring durability and longevity in challenging industrial settings.
The Beckhoff KL1104 is a versatile and robust component that simplifies the integration of digital inputs into your automation system, making it an essential part of any modern industrial operation.
