Special Electronics Module 2.50 mm² Short Description: The WAGO interface module RS-232/SMI provides a unified interface for SMI-LoVo-compliant electric drives. The interface represents a pure physical level conversion between the standardized RS-232 interface and the SMI-LoVo level. The interface module allows for the operation of up to 16 SMI-LoVo drives. The complete SMI functionality can be utilized. Communication between applications and SMI-LoVo drives occurs via special WAGO I/O-PRO function blocks. These blocks enable individual addressing, group addressing, and status queries. The SMI-LoVo interface module can be used with RS-232 onboard interfaces of programmable fieldbus controllers from the 750 series and with the serial RS-232 interface 750-650/003-000 or 753-650/003-000. The interface module must be externally powered with a DC voltage of 24 V. The 24V operating voltage and the RS-232 connections are galvanically isolated from the SMI-LoVo connections. The operating voltage connections are galvanically connected to the RS-232 connections. Installation is done on a mounting rail (TS 35).

About SMI: SMI stands for Standard Motor Interface, a standardized interface for electric drives. SMI was developed for connecting drives with integrated electronic circuitry for applications in roller shutters and sun protection systems.
