RelAir R2M Pro | Relay Australia | M-Bus | Automation Industries

The RelAir R2M allows you to integrate up to 63 Wireless M-Bus meters into your existing M-Bus installation. For this purpose the OMS-compliant gateway stores the meterdata and answers a request by the M-Bus master with the last answer telegram. Because of the configurable whitelist it is of course possible to run several RelAir R2M in one M-Bus network. Due to the integrated mini USB interface the RelAir R2M can also be used as a full operational Wireless M-Bus Master. Our new gateway works without an external power supply and is either powerd from the M-Bus (5 unit loads) or via the USB interface.
