The Beckhoff BC9120 from the BC Bus Terminals series by Beckhoff is a high-performance Bus Coupler designed for seamless integration into modern automation systems. It supports TwinCAT ADS and Modbus TCP protocols, ensuring robust communication across industrial networks. With a PLC cycle time of approx. 1 ms for 1,000 instructions, the BC9120 delivers rapid processing capabilities for time‑critical tasks. This unit manages up to 64 bus terminals (expandable to 255 terminals via K‑bus extension) and serves as the central interface for distributed I/O modules.

At the core of the BC9120 lies a versatile technical foundation. It features a Data Memory of 128 kbytes and Program Memory of 128 kbytes, backed by Remanent Data storage of 2 kbytes and an additional Persistent Data buffer of 1 kbyte to safeguard against unexpected power loss. The device offers dual RJ45 ports with a built‑in 2‑channel switch and automatic data transfer rates of 10/100 Mbit/s. It handles a maximum of 512 bytes for both fieldbus input and output streams. Programmers benefit from comprehensive IEC 61131‑3 language support (IL, LD, FBD, SFC, ST) and can perform online changes without system downtime.

The BC9120 accommodates up to 2,040 digital peripheral signals and 512 analog I/O signals, delivering extensive channel density in a compact package. Its 24 V DC power supply tolerance (–15%/+20%) ensures stable operation in fluctuating power environments. The module’s protocol versatility and automatic interface recognition simplify network commissioning and maintenance. Designed for industrial automation, the BC9120 excels in reliability and efficiency, making it ideal for complex machine control, process automation, and scalable I/O architectures where uninterrupted performance and flexible expansion are paramount.

Testimonials

We used Servo Supplier to refurbish old drives and buy reconditioned parts. We received great and timely service at a fair price. I recommend them to anyone who has aging equipment and can't find support from their OEMs. Highly recommend.

Bostik Inc.

WE absolutely LOVE Servo Supplier. They are quick, efficient and friendly. Honest too, which is huge in our industry. We deal with many different companies, and these guys are tops in our humble opinion. There has never been an issue with delivery, no warranties, no hidden fees, no surprises. Just what you want in the manufacturing business. Smooth, and we love smooth.

Technomech Inc

First-time customer. The ordering process was completely seamless. The part that we ordered was at our business within 2 days. Which was excellent! We had a piece of equipment down for a little more than 48 hours. Could have been a lot longer had we purchased from one of our normal suppliers.

Steve T. from NF&M International

I found these guys online and needed a somewhat obscure part quickly, and they delivered! Very quick process from the time I requested a quote to the shipping of my items. Great work Servo Supplier team!

FlexPac

Servo Supplier is my go to place for obsolete parts. They always seem to find them and the price is usually good. Any time I have questions they respond very quickly and professionally. I highly recommend them!

Justin Ball from Miba

Understood our situation, and worked to help us get it solved. Very responsive, and stepped out to keep me informed until the product arrived. Exactly as described, and promised.
