The iU891A-XL is a compact and cost–effective USB stick based on the Long Range Radio Module iM891A-XL that operates in the unlicensed 868 MHz band. It supports all major unidirectional and bidirectional wireless M-Bus modes (S, C, T and combined C/T) with packet formats A and B as well as the OMS security modes 5 and 7.
With an integrated +22 dBm power amplifier and a sensitivity of -149 dBm, a sensational link budget of approx. 170 dB can be reached. This makes the iU891A-XL an ideal solution for smart metering applications connecting water, heat, electricity and gas meters with data concentrators.
The external antenna provides an outstanding performance even in difficult RF environments.
The iU891A-XL requires a SMA antenna (i.e. Art. 404829 or 404825 ).
This is a hardware replacement for the former USB-Adapter iM871A-USB.
