Wago-789-913
Special electronic module

Special electronic module; 2.50mm²


The 789-913 RS-232/SMI LoVo Interface Module is a standard interface for SMI LoVo compatible electric drives. The interface expresses a clear physical level conversion between the standard RS-232 interface and the SMI LoVo signal level. The interface module can drive up to 16 SMI drivers. All SMI functions can be used. Special WAGO-I/O-PRO function blocks communicate between applications and SMI LoVo drivers. The module supports both single and group addressing and status monitoring. The RS-232 internal interfaces of the 750 Series programmable fieldbus controllers and the 750-650/003-000 or 753-650/003-000 serial RS-232 interfaces can be connected to the SMI LoVo Interface Module.

The module must be powered by an external 24VDC power supply. The RS-232 and 24V power supply is electrically isolated from the SMI LoVo connections. The power supply connectors are galvanically connected to the RS-232 connectors. The module can be mounted on a DIN rail.

SMI stands for Standard Motor Interface and is a standard interface for electric drives. SMI was developed to connect drivers to integrated electronic circuits for shutter and shutter systems applications.
