84 x 22 mm faceplate converter for DC12-28V microcurrent systems. It provides RS485 and 4G outputs and can convert AC voltage and current. Key benefits - Compact 84 x 22 mm faceplate fits tight panel spaces while delivering required functionality. - Wide input range DC 12-28 V with microcurrent suitability enables flexible integration in low power applications. - Dual communications: RS485 plus 4G for reliable local and remote data exchange and control. - AC voltage and current conversion capability expands compatibility with existing AC loads or measuring circuits. What makes it stand out - Small form factor combined with multiple interfaces (RS485 and 4G) supports both legacy field wiring and modern remote monitoring. - Clear focus on power and communication integration in one device, reducing enclosure count and wiring. 2-3 practical use scenarios - Scenario 1: In a factory floor panel where space is limited, monitor and control a DC12-28V sub-system remotely via 4G while communicating with a central controller over RS485. - Scenario 2: Retrofit of an HVAC or building automation system that uses AC loads, enabling voltage and current conversion alongside remote data reporting. - Scenario 3: Mobile or remote installations requiring cellular connectivity for status updates and control, with a compact panel mount solution that uses RS485 for local devices.
