A circuit protector compatible with industrial communication functions has arrived. An innovative product that allows for remote monitoring and control.

【Product Overview】 The 'REX12D-T' is an electronic circuit protector dedicated to DC24V that monitors current and voltage through industrial communication (IO-Link, ModbusRTU, with additional support planned for the future), allowing for appropriate protection. With the ability to monitor current and voltage, it becomes easier to understand equipment degradation, leading to preventive maintenance. It features a slim design with a width of 12.5mm for two channels and approximately 6.3mm or less for one channel. The elimination of bridging wiring on the top of the device enables the miniaturization of control panels. 【Capabilities of the Communication Function】 Remote operation of the circuit protector (On/Off/Reset) Monitoring of current and voltage Configurable alarm current values (50-100% of rated value) Acquisition of device and parameter information Disconnection information 【Hardware Features】 Push-in terminals Expansion possible up to 40A/maximum 16 channels Connection possible with lever wiring, eliminating the need for busbars One LED displays five status indicators Slim body of 12.5mm *For more details, please refer to the documentation. Feel free to contact us with any inquiries.
