Product Description:

The Beckhoff KL1804-0000 module is commonly used in industrial automation systems because it offers high energy efficiency and a sturdy enclosure. This module supports analog signals across four channels and is part of the KL Analog Input Module series. It has an operating voltage of 24 V DC and a range of ~ 15% to +20%, so it is well-suited for a variety of operational environments. It comes in a relatively small size and weighs 60 grams, and thus is suitable to be integrated into different systems.

The KL1804-0000 module supports 3-wire connection and conforms with the EN 61131-2 type 1/3 standard, thus making it compatible with numerous industrial control systems. It is capable of working with a "0" signal voltage that ranges between -3V to 5V and a "1" signal voltage that ranges between 11V - 30V. This module, combined with a standard input filter time of 3.0 milliseconds, effectively removes random or unwanted noise, helping ensure accurate input signal values. The current consumption is around 3 mA for each input, which makes it reliable for the type 3 digital input devices.

This module is designed to operate in the 0 degrees C to 55 degrees C temperature range, and it is effective for most indoor industrial applications. This unit draws less than 10 mA current when connected to the k-bus and about 1 mA plus with the power contacts, hence the power consumption is minimal. With the process image, the KL1804-0000 offers four digital inputs to assist in the acquisition of proper input signals. In summary, the Beckhoff KL1804-0000 is a highly reliable analog input module that is easy to incorporate into different automation systems.
