Isolated RS485 Module
Acts as a communication bridge between one RS485 interface and two galvanically isolated RS485 interfaces. Configurable as Slave–Slave, Slave–Master, or Master–Master.
- Power supply: 12–48 VDC over RS485 line
Bluetooth Module
Provides a wireless communication bridge between a wired RS485 interface and Bluetooth.
- Power supply: 12–48 VDC over RS485 line
Switching Control Module
Provides a switching output with energy-saving mode, ideal for components like solenoid valves. Includes a fail-safe watchdog that resets the output to a preconfigured state if control messages are lost.
- Communication: RS485
- Power supply: 12–48 VDC over RS485 line
