Programmable Logic Controller PLC Featuring Pluggable KL3064 Terminal Blocks For Simplified Maintenance

This product is a Beckhoff BECKHOFF KL3064 4-channel analog input bus terminal module, belonging to the PLC distributed I/O expansion unit. It is equipped with a plug-in separable wiring terminal structure and can be directly connected to the PLC bus control system.

Core Function: Collect the 0-10V single-ended voltage analog signals output by the on-site sensors, perform high-precision digital conversion of the analog signals, and then transmit them via the K-bus bus to the PLC main controller for calculation, logic control, and data monitoring. The plug-in terminal design supports quick disassembly and assembly of the module without disassembling the wiring, significantly simplifying the equipment's later maintenance, line maintenance, and fault replacement processes. It is a standard signal acquisition module for connecting on-site sensing devices and the central control host in industrial control PLC systems.

Terminal connection surface

• Plug-in terminals, simplified operation and maintenance

  The connection terminals and the main body of the module can be completely separated. When a module fails, there is no need to remove the on-site sensor wiring. Simply pull out the terminal head and replace the new module to complete the maintenance, which shortens the downtime for maintenance and is suitable for continuous production scenarios in the production line.

• 4-channel integration, high space efficiency

  A single module integrates 4 independent analog signal acquisition channels. The body width is only 12mm. The DIN rail is densely arranged for installation, significantly reducing the internal space occupied by the control cabinet and suitable for compact electrical control cabinet solutions.

• High-precision signal acquisition, stable and reliable data

  12-bit analog-to-digital conversion resolution, full-scale measurement error < ±0.3%. Built-in 500V electrical isolation to block on-site strong electric interference, avoiding PLC main control unit being broken by surges and noise waves, and improving the system's anti-interference ability.

• Bus configuration without configuration, plug-and-play

  Based on the K-bus bus automatic addressing communication, there is no need for manual code setting of addresses. It can be automatically recognized by the PLC when connected to the bus terminal block. The project debugging efficiency is significantly improved.

• Industrial-grade durable protection

  Complies with IEC anti-vibration and anti-shock industrial standards, supports wide temperature working environment, IP20 protection level is suitable for standard working conditions inside the control cabinet, standard shielding grounding terminals are provided to suppress long-cable signal drift.

• Bus passive power supply

  The module's working power is directly supplied by the rear K-bus bus, without the need for additional external power supply lines, simplifying the complexity of control cabinet wiring.
