Transmitter Module

Offloading all data coming from the IO modules

The IMBU Transmitter Module is responsible for offloading all data coming from the IO modules and data which is picked-up from e.g. the compressor-control panel or the customer’s SCADA system. Following hereafter are the standard specifications of an IMBU Transmitter Module.
