HART Communication Board

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. 1.Main Characteris 4 20mA output with digital communication of HART protocol(two-wire)Communication of interface: UARTSupport CPU failure alarmWrite-protect jumperIEC Ex intrinsic safety certificationEMC test certificationWith optical couplerSupport LCD and magnetism stick operationSupport Rosemount 275/375 ControllerSizeΦ65mmcustomized according to users requirements 2.Technical Parameter Power supply: 11.9 45VAccuracy: 0.02%High alarm current: =20.8mALow alarm current:=3.9mAPower supply of interface board:isolation 3.3V, 3 mAOperation temperature: - 40 85Damping adjusting: 0 32s, stepping 0.1s
