RC1180-MBUS Wireless M-Bus module

Radiocrafts AS has expanded its compact Wireless M-Bus RF module for use in Automatic Metering Reading (AMR) applications. The Wireless M-Bus standard (EN 13757-4:2005) specifies the communication between water, gas, heat and electricity meters or concentrators. The standard is becoming widely accepted in Europe as a basis for new Advanced Metering Infrastructure (AMI) installations. The RC1180-MBUS RF Transceiver Module is a compact surface-mounted high performance module measuring only 12.7 x 25.4 x 3.3 mm including shielding, replacing tens of components compared to a discrete design. The module is easy to use having a UART interface for serial communication and configuration, and a one-pin antenna connection. The new module supports two-way communication, enabling not only meter reading but also valve control and data acknowledgement. It meets the Wireless M-Bus specification for all S1/2, T1/2 and R2 modes, and operates at 12 channels in the 868 MHz frequency band. The RC1180-MBUS module is pre-certified for operation under the European radio regulations for license-free use. When used with quarter-wave antennas a line-of-sight range of 500-600 meter can be achieved. The module is designed for use in battery operated systems with up to 20 years of battery lifetime.
