SMA I/O Interface (MD.IO-40) for STP50 Core1
The SMA I/O Module is a module with 6 digital inputs and 1 digital output operating as a multifunction relay. The SMA I/O Module enables the implementation of grid management services for up to 12 SMA inverters in a network with the same system password. The SMA I/O Module must be installed in one SMA inverter. For the implementation of grid management services, the SMA I/O Module receives the specifications of the grid operator via a ripple control receiver. The SMA I/O Module transmits the specifications of the grid operator via Speedwire network to a maximum of 11 further SMA inverters. The multifunction relay can be configured for various operating modes. The multifunction relay can, for example, be used for switching fault indicators on and off.
