NCS-FI105 fieldbus to current Converter is used to convert fieldbus signals to conventional analog signals. It can receive fieldbus signals, and convert them to 4-channel 4~20mA analog signals. NCS-FI105 is the converter between fieldbus system and control valve/other actuator.
As a conversion device, NCS-FI105 converter can receive Foundation fieldbus or profibus PA signal and convert to 4~20mA analog signal of 4 channels.
Dimension (Unit:mm)
Wiring
The power and signal of NCS-FI105 converter Transmitter are sharing one pair of cables (Bus Cable).
Installation
For installation of NCS-FI105 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-FI105 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-FI105 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-FI105 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.
Wiring
The power and signal of NCS-FI105 converter Transmitter are sharing one pair of cables (Bus Cable). NCS- FI105 converter is suggested to use specific Fieldbus cables recommended by the IEC61158-2. The wiring terminal is at the rear cover side, the wiring terminal board could be seen when the rear cover is screwed.

Figure 2.6 Wiring of NCS-FI105 Converter
Signal wires should be passed the wire hole. Sensor signal wires are single-point grounding. The Shield of the bus cable should be floating in converter side, and be grounding in bus power side.
The signal and bus cable should not share the line pipe or trunkings with other equipment, and should stay away from high-power equipment
