Description



The WAGO RS-232/SMI interface module offers a standard interface to SMI-compliant electrical drives. The interface represents a purely physical level conversion between the standard RS-232 interface and the SMI signal level. The interface module operates up to 16 SMI drives. The entire SMI range of functions can be used. The special WAGO-I/O-PRO function blocks communicate between applications and SMI drives. The modules support both single and group addressing, as well as status monitoring. The SMI Interface Module can be used with RS-232 onboard interfaces from 750 Series Programmable Fieldbus Controllers and with the serial 750-650/003-000 or 753-650/003-000 RS-232 Interface. The module must be supplied with an external 24VDC power source.The 24V power supply and RS-232 connectors are galvanically isolated from the SMI connectors. The power supply connectors are galvanically connected to the RS-232 connectors. The module is DIN-rail mountable.

Notes on SMI:

SMI stands for Standard Motor Interface, a standard interface for electrical drives. SMI was developed for connecting drives with integrated electronic circuitry for applications in shutters and sunshade systems.
