NCS-IF105 converter Quadruple Channel Current 4-20mA to Fieldbus Converters/Current to Fieldbus Converter
Current to Fieldbus Converter Brief Introduction
As intelligent transition device, NCS-IF105 converter receives 0~20mA or 4~20mA analog signal (4 channels) and converts into fieldbus signal. NCS-FI105 converter uses digital communication technology, and makes the interface between field device and controller easier, and reduces the expense of installation and maintenance.
NCS-IF105 converter fulfills the need of FF fieldbus intelligent instrument and can connect with several FF fieldbus devices. NCS-IF105 converter has abundant function blocks and realizes not only normal measurement function also complex control strategy. In order to realize different function, user can choose different function blocks according to requirements and specific application environment.

Current to Fieldbus Converter Installation
For installation of NCS-IF105 converter, three types of bracket (pipe mounting flat bracket, plate mounting angle bracket and pipe mounting angle bracket) are provided. Accordingly there are three installation methods as the following.
The installation of pipe mounting flat bracket: the typical installation as Figure 2.1 shows. Fix NCS-IF105 converter in flat bracket using four bolts provided, and then fix the flat bracket on the vertical pipe in Φ50mm around through the U-shape bolt provided.
The installation of plate mounting angle bracket: the typical installation as Figure 2.2 shows. Fix NCS-IF105 converter in angle bracket using four bolts provided, and then fix the angle bracket on the plate through the M10 bolt not provided.
The installation of pipe mounting angle bracket: the typical installation as Figure 2.3, 2.4 shows. Fix NCS-IF105 converter in angle bracket using four bolts provided, and then fix the angle bracket on the horizontal pipe in Φ50mm around through the U-shape bolt provided.
Current to Fieldbus Converter Principle and Structure
NCS-IF105 converter convert input current signal that generate by most conventional transmitters to fieldbus signal.
NCS-IF105 converter is consisted of five components, as shown in Figure.
1)Terminal board: it is used to connect with fieldbus, current output signal, A/D board and communication board.
2)A/D board: it can convert input current signal to digital signal provided to communication board.
3)Communication card: it is core component of intelligent instrument, which implements the communication, control, diagnosis and maintenance of Foundation Fieldbus.
4)Isolation board: it is used for isolation between communication board and instrument board (power isolation and signal isolation).
5)LCD Card (optional): it is used to display function block parameters.
