7. Strong resistance to electromagnetic interference,protects fieldbus devices. Overview NCS-BP105 Fieldbus Power Conditioner (Hereinafter refers as fieldbus power supply) applies to Foundation Fieldbus and Profibus PA control system and provides power to fieldbus instrument. Fieldbus Power conditioner adopts an active impedance control circuit , Prevents the conventional power supply from absorbing the Fieldbus signal.
Appearance and Dimension Main technical specification 4.1 Basic Parameters Output 15V~34V (requires isolation between input power supply and the earth) voltage output 2~6V,related to the load size voltage drop Rated output 330Ma current Overcurrent >360mA protection -30 ~ 70 ℃...
1: NCS-BP105 Fieldbus Power Conditioner adopts non-isolation method between input and output, in order to guarantee the reliability of long distance communication, For ordinary regulated power supply, it can meet the requirements as long as the output port doesn’t connect to the ground.
When adopting redundancy mode connection, user should disconnect the J4 jumper in the fieldbus power supply. No special requirements, we tacitly approve J4 closed when delivery. If user wants to double power supply redundancy operates, the statement should be announced before ordering.
