Fatek FBs-20MC PLC Advanced Main Unit – 20 I/O Points

Fatek – FBs-20MC PLC Advanced Main Unit is a high-performance controller engineered for small-to-medium industrial applications that require robust logic processing and time-based control. Offering a total of 20 I/O points (12 Digital Inputs and 8 Digital Outputs), this unit provides exceptional versatility in a compact DIN-rail mountable housing.

Description

In the realm of industrial automation, efficiency and ease of maintenance are critical. The Fatek – FBs-20MC PLC Advanced Main Unit utilizes Fatek’s proprietary System on Chip (SoC) technology. This advanced chip architecture integrates the CPU, hardware logic solver, and communication ports into a single component, significantly reducing the size of the unit while increasing its resistance to electrical noise and vibration.

Advanced Functionality: The MC Advantage While similar in size to economy models, the FBs-20MC offers superior functionality. The integrated Real-Time Clock (RTC) allows engineers to program time-scheduled events, such as shift-based data logging, automated lighting control, or periodic pump cycling, without needing external timing modules. Additionally, the unit supports high-speed counters and interrupt functions, enabling it to handle fast-moving processes with precision.

Maintenance-Friendly Design One of the most practical features of the FBs-20MC is the use of 7.62mm detachable terminal blocks. In the event of a system upgrade or unit replacement, technicians can simply unplug the wiring harness without disconnecting individual wires. This feature dramatically reduces downtime and potential wiring errors during maintenance.

Scalability and Connectivity The unit comes equipped with a standard Port 0 (RS-232) for programming and HMI connectivity. It is fully expandable, allowing users to add communication boards (RS-485, Ethernet), analog modules, or temperature controllers via the expansion interface, ensuring the system can adapt as your production requirements evolve.
