123electric BMS123 Smart - Dual Relay

123electric BMS123SM-REL

You can switch any high current or signal with this easy to use dual relay. The extremely energy-saving design ensures a very long operating time even with a very small battery capacity. It provides high performances with minimal costs. You do not need to redo your current installation. If this dual relay suits your application, you can simply replace the existing contactors with an energy-saving smart relay.

Main advantages

• The relay works with a permanent signal with very little power consumption
• Dual relay can be used with BMS123Smart to switch loads and chargers
• When both relays are active, it is very energy efficient, consuming less than 0.5mA
• High resistance against noise, therefore can be used in an industrial environment
• One device can be used for all applications, it can be used for 12V and 24V battery modules
• Each relay can switch 120 A at 12 V, 60 A at 24 V
• Simple interface. Just connect the battery module + and - to the module and the wire from the signal relay on the OUT board to the 123SmartRelay to turn the relay on/off like a normal relay
