Beckhoff LC8301 Qsm Coupler 4-086-05-0563 Homag Control Module

1、Clear Channel Configuration and Signal Specifications

It is fixedly equipped with 8 digital input channels, each supporting dry contact or PNP/NPN sensor signal input. The input voltage range covers 24V DC (-15%~+20%), and the typical input current is 2.5mA (per channel). It is compatible with mainstream digital sensor signal types in industrial scenarios, providing clear hardware specification support for signal acquisition.

2、Hardware-Level Electrical Protection Design

It has built-in overvoltage protection and short-circuit protection circuits. When the input voltage fluctuates abnormally or a line short-circuit occurs, it can quickly cut off the fault circuit to prevent damage to internal components of the module. At the same time, it has an electrical isolation capability of 500V AC (for 1 minute) (between input and power supply/bus), which effectively blocks interference signals between different circuits and ensures long-term stable operation of the module.

4、Standardized Wiring and Connection Methods

It adopts screwdriver-actuated spring-loaded terminal blocks, supporting solid conductors (0.14~2.5mm²), stranded conductors (0.14~2.5mm²), and ferruled conductors (0.14~1.5mm²). The required wire stripping length is 8~9mm. Wiring operations do not require special tools, and the terminal contact pressure is stable, reducing the risk of poor contact during long-term use.

5、Compliant Industrial Safety Certifications

It has obtained multiple international industrial safety certifications such as CE, UL, and CSA, and complies with standards including EN 61131-2 (general standard for industrial control equipment) and EN 61000-6-2 (immunity standard for industrial environments). It meets the industrial equipment access requirements of most regions around the world, including Europe and North America, and is suitable for the global production layout of multinational enterprises.

6、Low Power Consumption and Efficient Heat Dissipation Structure

The typical power consumption in working state is only 1.2W (when powered by 24V DC), which has little impact on the power load in the control cabinet. The shell is made of polycarbonate material, with hidden heat dissipation grooves on the surface. Combined with the compact internal component layout, it can quickly dissipate working heat through natural convection, avoiding performance degradation caused by high temperatures.

1、Beckhoff LC8301 is a digital input bus terminal module specially designed for industrial automation scenarios. It belongs to the Beckhoff Bus Terminal System, with its core function being to achieve accurate acquisition and reliable transmission of digital signals in industrial fields, providing real-time and stable on-site data support for upper-level control systems (such as PLCs and industrial computers).

2、n terms of hardware structure, the module adopts a standardized industrial design, with a housing made of polycarbonate that combines durability and lightweight characteristics. Its overall dimensions are 64mm in width × 124mm in height × 102mm in depth, and it supports 35mm DIN rail mounting (compliant with EN 60715/EN 50022 standards). It can be flexibly embedded in various industrial control cabinets and can be seamlessly spliced with other Beckhoff bus couplers (such as the BK series) and terminal modules, adapting to the compact layout requirements inside the cabinet. The terminal adopts screwdriver-actuated spring-loaded terminals, supporting solid conductors (0.14~2.5mm²), stranded conductors (0.14~2.5mm²), and ferruled conductors (0.14~1.5mm²). The required wire stripping length is 8~9mm, and wiring can be completed without special tools, balancing operational convenience and long-term connection stability.

3、In terms of functional configuration, the LC8301 is fixedly equipped with 8 digital input channels. Each channel supports dry contact signals and PNP/NPN sensor signal input, and is adapted to 24V DC power supply (allowing a voltage fluctuation of -15%~+20%). The typical input current per channel is 2.5mA, which is compatible with mainstream digital sensor types in industrial scenarios. At the same time, the module has built-in hardware-level protection mechanisms, including overvoltage protection (to deal with abnormal high voltage on the input side) and short-circuit protection (to prevent short circuits in the input line). Moreover, there is an electrical isolation capability of 500V AC (for 1 minute) between the input and the power supply/bus, which can effectively block circuit interference, avoid damage to components, and ensure the long-term stable operation of the module in complex industrial environments.

4、In addition, the module also features user-friendly operation and maintenance design: it is equipped with intuitive LED status indicators that can provide real-time feedback on power on/off, signal input status of each channel, and module faults, facilitating staff to quickly locate problems; it supports parameter configuration via the Beckhoff KS2000 configuration software or bus interface, without the need for complex hardware debugging; the typical power consumption in working state is only 1.2W. Combined with the hidden heat dissipation grooves on the housing and natural convection cooling method, it can effectively control the temperature rise of the module and avoid performance degradation caused by high temperatures. In terms of compliance, the LC8301 has obtained international certifications such as CE, UL, and CSA, and complies with EN 61131-2 (General Standard for Industrial Control Equipment) and EN 61000-6-2 (Immunity Standard for Industrial Environments). It can meet the industrial equipment access requirements of most regions around the world and adapt to the global production layout of multinational enterprises.
