MEXM-1

Daisy chain MEXM-1 units together and:
Add up to 128 extra Metering inputs to any one of your Davicom units
Add up to 192 extra Status inputs to any one of your Davicom units
Add up to 72 Relay outputs to any one of your Davicom units

For example, 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 unit’s powerful control, monitoring and automation functions.

Each MEXM-1 scans all its inputs and outputs at a 10Hz rate for fast detection and control.

# In Modbus RTU mode, subtract 24 Status inputs.

MEXM-2

For example, adding a single MEXM-2 with its 64 inputs to a DV-Micro yields a total of 72 Status inputs in a cost-effective package. These extra inputs are directly integrated into the DV-Micro’s control structure, therefore taking full advantage of the unit’s powerful control, monitoring and automation functions. You may mix MEXM-2 units with other members of the Davicom MEXM family in order to add more Status inputs, Metering inputs and Relay outputs.

NOTE: The maximum number of usable I/O’s from any MEXM combination is determined by the Davicom unit firmware, not by the number of MEXM units used. Contact us for more details.

For better control and faster response time, all the inputs of the MEXM-2 are scanned 10 times per second (10 Hz).
