NCS-BP105 Fieldbus Power Conditioner NCS-BP105 Fieldbus Power Conditioner applies to Foundation Fieldbus and Profibus PA control system and provides power to fieldbus instrument. Fieldbus Power Conditioner adopt an active impedance control circuitï¼?prevents the conventional power supply from absorbing the Fieldbus signal otherwise interfering with the operation of the Fieldbus. Working with terminator together, it provides perfect bus signals. There are two LED for power indication and fault indication. Fieldbus Power Conditioner can support redundancy when two Power Conditioners work in redundancy mode in order to enhance the reliability of the system. NCS-BT105 Fieldbus Terminator NCS-BP105 Fieldbus Terminator mounted in two side of the bus, applies to Foundation Fielbus and Profibus PA control system in order to provide impedance matching and convert bus current to voltage.
