RS485 Interface for Weighing Scales – Long-Distance, Multi-Device Communication Made Easy
Price on Request
At Hindustan Scale Company, we understand the need for reliable, long-distance data communication in modern industrial environments. That’s why we offer RS485 connectivity across our entire range of weighing scales, including platform scales, crane scales, tank weighing systems, and custom industrial solutions. With RS485, you can connect multiple devices over extended distances with minimal signal loss and maximum reliability.
Ideal for factories, warehouses, automation setups, and harsh industrial sites, the RS485 interface enables multi-drop network configurations, allowing you to monitor and control multiple scales from a single control room or PLC. It’s built for durability, stability, and easy integration into your SCADA, ERP, or industrial control systems.
- Perfect for long-distance communication (up to 1200 meters)
- Supports multi-device networking (up to 32 devices)
- Noise-resistant and interference-proof for industrial environment
- Compatible with all HSCo weighing systems
- Easy integration with automation and data logging software
- Custom wiring and port configurations available
For intelligent weighing systems that span across your facility, RS485 is the communication backbone you can trust. Powered by Hindustan Scale Co.’s expertise since 1955, we help your operations run smoother, smarter, and more connected than ever before.
Which one is this? The RS485 add-on for a scale you already own (HSCo or most other makes), fitted and configured to your system. Want a new scale with the RS485 built in? See the RS485 Port Customized Scale.
Want it fitted to a scale you already use? See weighing scale upgrades: HSCo fits the port and arranges the Legal Metrology re-verification where it is required.
RS485 weighing scale: questions buyers ask
An RS485 weighing scale sends its weight to a PLC, SCADA system or industrial PC over a serial link made for long cable runs and several scales on one line. HSCo fits RS485 to platform scales, crane scales, tank weighing systems and custom builds, in plain weight text or Modbus RTU, whichever your controller expects.
The RS485 standard allows cable runs of about 1,200 metres, which is why it is the link for a scale in one shed and a control panel in another. The practical distance depends on the cable, the speed and the termination, so tell us the run; HSCo specifies the cable, fits the termination and sets the speed to match.
Yes. RS485 supports several devices on one line; the standard allows up to 32. Addressing and polling depend on the protocol, not on RS485 alone, so HSCo sets the output and, where needed, the device addresses to match your controller. Tell us how many scales you need to connect and which PLC or PC will read them.
Whichever your PLC expects. Modbus RTU and plain weight text are the options, and there is no fixed default protocol. Send the controller requirements and we set the baud rate, parity, stop bits and data format to suit. If you need Modbus, tell us the register layout your programmer expects.
Any HSCo scale can be built with RS485 or upgraded to it. Product pages that already name RS485 include the PLCHQBT Bluetooth platform scale, SSBBT Bluetooth table-top scale, GRSSB grading scale, GRSSSWR waterproof grading scale, POS Indicator and ABSWRSS stainless steel waterproof scale, along with the HSC-IMW In-Motion Weighbridge and the HSC-BWC Batch Weighing Controller. If your scale is not on this list, it can still have the port.
