Want to multiply your Davicom’s input and output points? The MEXM-1 will help you do that! Adding a single MEXM-1 to a DV-Micro yields a total of 32 metering inputs, 32 status inputs and 32 relay outputs for a very low price. These extra I/O’s are directly integrated into the DV-Micro’s control structure, therefore taking full advantage of the Davicom’s powerful control, monitoring and automation functions.
