Two-channel relay module WB-MRM2-mini v.2 is designed for use in building automation systems. The WB-MRM2-mini v.1 featured all-in-one terminal blocks and a lower height (46 mm). The module is mnaged from the controller [[Wiren Board 6/en|Wiren Board 6]] or a computer via the bus [[RS-485/en| RS-485]] via [[Relay Module Modbus Management/en |Modbus Protocol]], as well as via external buttons connected to the module. Miniature dimensions of the module allow you to mount it next to the load in the cable channels, bowls lamps, deep installation boxes for sockets and switches. | Two-channel relay module WB-MRM2-mini v.2 is designed for use in building automation systems.

The module version NO (normally open contacts) has two relays HF32F-G ([http://www.hongfa.com/pro/pdf/HF32F-G_en.pdf Datasheet]) switching the corresponding 2 outputs. Relay outputs are output to screw terminals. In case of active (resistive) load, the relays can switch up to 7 A/230 V AC and up to 7 A/30 V DC. In the case of reactive (capacitive or inductive) load (motors, switching power supplies, etc.), do not switch current more than 400 mA. Use external contactors designed for the appropriate load. | The module version NO (normally open contacts) has two relays HF32F-G ([http://www.hongfa.com/pro/pdf/HF32F-G_en.pdf Datasheet]) switching the corresponding 2 outputs.

An example of controlling a WB-MRM2-mini relay module with a Wiren Board 5 controller and programming control scenarios will be discussed in a simple layout, where the relay module is the only device connected to the controller (see the diagram in [[#Mounting|Mounting]]). Normally open button without fixation is connected to input 1 and GND. 12 V power is supplied to the V+(+) and GND (- ) inputs. The RS-485 A and B inputs/outputs of the first controller port and the WB-MRM2-mini module are connected. | <div class="mw-translate-fuzzy"> | ||
