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.
