SmartMeter dry contact

VMC Pressure Controller, adjustable.

This OMS-Sigfox and LoRawan radio module allows multiple information to be collected simultaneously. Our know-how in RF, offers us extremely long autonomy of the order of more than 12 years with a rate of sending data every 32 seconds in the OMS framework and, on the other hand, are only from 1 year to 10 years in the other versions of radio protocols [s1]. It meets the 13757-3, -4 and TC294 standards and is compatible with OMS 2.00 and 3.00 in T1, C1 modes. It is possible to program this module according to your needs and it can be received by all compatible and approved WirelessMbus systems.
A robust AES128 or 256 level encryption key can, depending on the customer’s needs, secure data transmissions. As part of Sigfox and LoRawan transmissions, the sending rates can be programmed from 10 minutes to several hours, with our USB Dongle programming tools. LoRawan and Sigfox transmissions are not encrypted.
