Product Description:

The KL1154 analog terminal from Beckhoff is commonly used within EtherCAT I/O systems. It functions where each terminal handles specific input or output signals. Beckhoff is well-known for constructing distinct advanced and high-class motors with drives for industrial control.

The KL1154 bus terminal utilizes connection technology with 2-wire and 3-wire support. It operates with positive or ground switching by allowing direct connection of sensors or signal contacts into control systems. An integrated input filter with a typical response time of 3.0 milliseconds is provided by reducing the risk of incorrect signal detection caused by electrical noise or contact bounce from mechanical switches. The terminal includes four separate digital input channels. In the process image each input is assigned a 1-bit width by permitting simple signal mapping. This setup eliminates the need for manual address settings or configuration adjustments, which simplifies both the installation and the system integration steps. It carries CE marking for electrical safety and electromagnetic compatibility. Its structural design supports easy mounting into distributed I/O systems where digital input signals need to be collected from field devices. The terminal connects directly into the bus terminal series by transmitting the input signals without the need for additional wiring complexity.

The KL1154 terminal module weighs only 55 grams which makes it manageable and lightweight for fitting in equipment enclosures or control panels. It is designed to operate in the temperature range of 0 to 55 degrees Celsius. This range guarantees that the module maintains its effectiveness under normal usage situations by supporting steady execution. Because of its design, the device functions safely across this range of temperatures by providing consistent functionality for electronic input services where the accuracy of the signal is vital.
