Fit the IO 351 by hooking the top on the DIN rail and holding the bottom against the rail. Module dimensions and minimum clearance above and under the module, see 13. IO 351 is prepared for mounting on a 35 mm DIN rail (EN 50022). IO 351 has not been damaged during transportation.IO 351 is suitable for the supply voltage and frequency on the installation site.variant corresponds to the one ordered.IO 351 is only intended for factory wiring. Terminals for digital inputs and analog outputs Terminals for Inputs for PTC sensor or thermal switchįor pumps with fixed speed and pumps controlled by external frequency converters or as input-output module Permissible supply voltage, frequency and maximum power consumption IO 351 A has five terminal blocks, IO 351 B has eight, see fig. It can also be identified by the number of terminal blocks. The variant (A or B) is stated on the nameplate on the back. OPEN TYPE PROCESS CONTROL EQUIPMENT 30 XP Terminals for inputs for PTC sensor or thermal switch Indicator lights and transmitter/receiver for communication with R100 If IO 351 is used in a manner not specified by the manufacturer, the protection provided by IO 351 may be impaired.Įnglish (GB) Installation and operating instructions If the instructions are not followed, there is a risk of personal injury.
