Translations:WB-MR3xV and WB-MR6xV Modbus Relay Modules/14/en

The inputs of the WB-MR3xV and WB-MR6xV modules are connected to screw terminals. Depending on the model, the modules have discrete inputs of different types. In LV modification inputs are organized on the principle of "dry contact". Buttons or switches are connected between the corresponding input of the Inputs unit and the GND. In the HV modification, the inputs determine the presence of a connected phase of the 220 V AC network. Input voltage: 90V — 250V AC. External buttons and switches are connected between the corresponding input of the Inputs unit and the phase. The 230V neutral (N) is connected to the terminal "N" of the module.
