Fieldbus Power Conditioner Fieldbus Terminator

Fieldbus power regulator (hereinafter referred to as fieldbus power) is applied to Foundation Fielbus and Profibus PA fieldbus control systems to supply power to bus-powered devices.The bus power supply adopts the active impedance control mode, which can greatly improve the carrying capacity compared with the simple passive scheme.It also provides uniform impedance characteristics, which, in conjunction with the terminal matcher, reproduce perfect bus signals.There are two leds on the bus power panel for power indication and overcurrent indication respectively, which is convenient for maintenance.An optional terminal matcher is provided internally in the bus power supply and can be used internally when the bus power redundancy is not in use.Bus power supply can support power redundancy, when two bus power supply redundancy connection, can further improve the reliability of the system.The field bus terminal matcher (hereinafter referred to as the bus terminal) is matched with the bus power supply and installed at the end of the bus to realize the impedance matching function of the signal and complete the conversion from the current signal to the voltage signal.

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 circuit，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.
