The WM-Bus modules make sensible meters and IoT gadgets join simply. They use much less energy, keep safe, and slot in small areas.
Quectel Wi-fi Options’ KCMCA6S collection of sub-GHz Wi-fi M-Bus (WM-Bus) modules helps builders rapidly add dependable, safe, and low-power connectivity to sensible metering and IoT gadgets. The modules assist a number of WM-Bus modes (T, C, S, R, N, F), versatile frequency configurations, and dynamic multi-mode switching, making them ideally suited for functions in water, electrical energy, fuel, warmth, and different IoT eventualities. Their compact design and built-in software program stack scale back the necessity for third-party protocol integration, saving time and price in product improvement.
The KCMCA6S collection operates throughout 868MHz, 169MHz, and 433MHz bands and complies with the EN13757-4 customary, guaranteeing seamless integration into superior metering infrastructure (AMI) techniques. The modules function a low-power structure with built-in multi-layer safety, supporting long-term, dependable operation in each customary and space-constrained gadgets.
Accessible in two variants, the KCMCA6S features a Floor Acoustic Wave (SAW) filter to cut back interference from mobile communications, which is helpful for gadgets combining WM-Bus with NB-IoT or Cat-1, whereas the KCMCA6S-N supplies the identical capabilities with out the SAW filter.
Designed for compact installations, the modules are available an LCC kind issue measuring 25.4mm × 14.0mm × 2.9mm and function in temperatures from -40°C to +85°C. Every module integrates an ARM Cortex-M33 processor working as much as 78MHz, 32KB of RAM, and 256KB of Flash reminiscence, providing an entire all-in-one answer for dependable sub-GHz wi-fi connectivity.
“The KCMCA6S collection WM-Bus modules are well-suited for sensible metering use circumstances within the well-established European sensible metering and AMI techniques market and we additionally foresee a variety of potential functions throughout different IoT connectivity eventualities,” commented Delbert Solar, Vice Basic Supervisor and Product Head, Quectel Wi-fi Options. “We’re proud to carry these compact modules with a number of interfaces to the market to ship steady community connections with sturdy anti-interference and dependable knowledge transmission.”
