Interface Resistance RB 57 - Control device combination IP20 789-912 – WAGO – 4050821100317: Interface Resistance RB 57 789-912 Number of command points 0 Number of pushbuttons 0 Number of indicator lights 1 Number of key switches 0 Number of selector switches 0 Number of mushroom buttons 0 Rated control supply voltage Us at DC 24...24V Color of the upper part of the housing grey, housing material plastic, number of NO contacts 0, number of NC contacts 0, number of changeover contacts 0, degree of protection (IP) IP20, The RS-232/SMI interface module creates a uniform interface to SMI -compliant electric drives provided. The interface represents a purely physical level conversion between the standardized RS-232 interface and the SMI level. The interface module enables the operation of a maximum of 16 SMI drives. The full range of SMI functions can be used. The communication between applications and SMI drives takes place via special WAGO-I/O-PRO function blocks. The blocks enable individual addressing, group addressing and status queries. The SMI interface module can be used with RS-232 onboard interfaces of programmable fieldbus controllers of the 750 series and with serial RS-232 interfaces. The interface module must be externally supplied with a direct voltage of 24 V for the supply. The 24V operating voltage and the RS-232 connections are galvanically isolated from the SMI connections. The operating voltage connections are galvanically connected to the RS-232 connections. It is mounted on a mounting rail (TS 35)
