The screw-free terminals b1 and b2 of the module have 2 inputs of the dry contact type, not isolated from the power supply. RC chains are used on each input line to eliminate contact chatter. The inputs are pulled up by resistors to the +3.3 V power line. Buttons or switches with locking are connected between the GND pin and the corresponding b1 or b2 input. The inputs can be used as general-purpose inputs, for counting signals and for direct control of relay channels.

Входы имеют несколько режимов работы, в частности поддерживаются триггерный режим (для управления с помощью кнопок) и режим повторения входа (для управления с помощью выключателей). В триггерном режиме для изменения состояния реле достаточно однократно замкнуть и разомкнуть вход. Изменение состояния происходят по переднему фронту (то есть при замыкании). В режиме повторения состояние реле определяется состоянием входа: вход замкнут реле включено, разомкнут выключено. Подробно о режимах работы входов написано в разделе [[Relay Module Modbus Management|Управление модулями реле Wirenboard по протоколу Modbus]].
The inputs have several modes of operation: trigger mode (for control with buttons) and repeat mode (for control with switches). In the trigger mode, to change the state of the relay, it is enough to close and open the input once. The change of state occurs on the rising edge (that is, when the circuit). In the repeat mode, the relay state is determined by the input state: the input is closed the relay is on, open the relay is off. Details about the mode switching  are written in [[ Modbus Management Of Relay Modules/en|Modbus Management Of Relay Modules]].
