Fieldbus Terminator

Product Overview

The fieldbus power conditioner (hereinafter referred to as the bus power) is suitable for Foundation Fieldbus and Profibus PA fieldbus control systems, providing power to bus powered devices. The bus power conditioner adopts active impedance control method, which can greatly improve the load capacity compared to simple passive solutions; At the same time, it provides uniform impedance characteristics and, when combined with terminator, it can reproduce perfect bus signals. There are two LEDs on the bus power panel for power indication and overcurrent indication, which facilitates maintenance. The bus power conditioner integrates a terminal matching device internally. The bus power conditioner supports two redundant power inputs, which can further improve the reliability of the system.

The fieldbus terminator (hereinafter referred to as the bus terminator) is used in conjunction with the bus power conditioner, installed at the end of the bus, to achieve impedance matching of signals and complete the conversion of current signals to voltage signals. When the bus junction box used in the bus supports terminal matching function, there is no need to install a fieldbus terminator separately for the bus.

NCS-BT105 Fieldbus Terminator Connection：

Note 1: The input and output of this bus power conditioner are non isolated. In order to ensure reliability during long-distance communication, it is required that the output of the power supply be isolated from the ground. For ordinary regulated power supplies, as long as the output terminal is not grounded, this requirement can be met. In addition, the regulated power supply for the bus power conditioner should be dedicated and avoid supplying power to other devices as much as possible. At the same time, do not use the same regulated power supply to power buses from different network segments. If the regulated power supply has multiple isolated outputs, the unused output power supply can supply power to other devices or separately supply power to bus power supplies that are not in the same network segment. If the above conditions cannot be met, please choose an isolated bus power conditioner product.

Note 2: When the bus junction box used in the bus supports terminal matching function, there is no need to install a fieldbus terminator device separately for the bus.
