Translations:WB-MR3xV and WB-MR6xV Modbus Relay Modules/22/en

The screwless terminal blocks on the relay Board are used to connect power lines, control (RS-485) and input contacts. When used with the mounting lugs of the type NSVI to install wires into screwless terminals it is necessary that the diameter of the insulated cuff does not exceed 3.6 mm, wire size — 0.75 mm², and the length of the conductive sleeve — 5-6 mm. Screw terminals accept wire cross-section 2,5—4 mm². The cross section of the wire must correspond to the switched load.
