DRG-2400 RS485 (half-duplex input) Turn RS232 isolated safety barrier

Picture Name

Classification:

DRG series

The DRG-2400 RS485 to RS232 isolated safety barrier enables two-way communication between the RS485 digital signal and the RS232 digital signal in the safe zone, and provides power to the field instrument. The product needs to be independently powered, and the power supply, input and output are isolated.
