NCS-IF105 converter Quadruple Channel Current 4-20mA to Fieldbus Converters
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.
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.
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 Picture.
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.
