MAC expansion module
The MEXM-1 adds extra I/O capability to any Davicom MAC product. Each MEXM-1 adds 24 metering inputs, 24 status inputs and 24 relay outputs that are automatically integrated into the MAC's control structure. They therefore take full advantage of the MAC's powerful control, monitoring and automation functions. A Davicom MicroMAC with a single MEXM-1 yields a total of 32 metering inputs, 32 status inputs and 32 relay outputs. Up to eight MEXM-1 units can be used together and, if connected to a MAC216, will give a total of up to 144 metering inputs, 224 status inputs and 104 relay outputs. Metering input ranges cover ±2.5, ±5, ±10, ±25 and ±50V.
