4 - 20mA output with digital communication of HART protocol(two-wire) Support CPU failure alarm

NCS-RC105 HART Communication Board

PCB Assembly/PCBA/PCB and Components Supplier

 

NCS-RC105H HART communication board is developed with the standard of HART protocol. It becomes the digital field device combined with traditional instruments, so it can be used as HART or 4-20mA instrument. NCS-RC105H HART communication board provides the function of control, capture/output and display for field device.
