Product Description

The KL1809-KL1809 is one of the analog input modules developed by Beckhoff in the KL Analog Input Series. This module is designed robustly enough to accept directly digital signals with high accuracies. It operates at 24 V DC (-15%/+20%) nominal voltage among many industrial automation applications. This module allows the desired signal processing with an accurate signal voltage '0' between -3 to +5 V and signal voltage '1' in the range of 11 to 30 V. It is available in multiple kinds of signal types as confirmed in the EN 61131-2 (type 1/3) standards.

It has an input filter with a delay of 3.0 ms, which allows for noise filtering and accurate signal reading for high-speed and sensitive applications. At the same time, the module takes 20 mA from the K-bus, and its current consumption at the power contacts is 4 mA plus load. Its input current is generally 3 mA, so this terminal is in conformity with the specifications of EN 61131-2, type 3 and hence, an energy-efficient as well as extremely effective terminal in data acquisition.

Intended for use in challenging environments, the KL1809 is qualified for a working range from -25°C to +60°C, while storage can be made at temperatures ranging from -40°C to +85°C. The module has passed serious compliance tests against vibration as well as shock resistances corresponding to the standards of EN 60068-2-6 and EN 60068-2-27. It also passed the conformity test concerning electromagnetic compatibility according to EN 61000-6-2/EN 61000-6-4. Module with a protection rating of IP20 appropriate for indoor use and carrying CE, UL, ATEX, IECEx, and DNV GL approvals can be considered as reliable and compliant within industrial applications.
