Profibus PA/FF H1 Distributor
Introduction
Now, BFPD (101, 102... Topology connection mode.) the main – spur of the instrument and the most popular among. The trunk line, transport energy and data to the scene. And then distributed to each branch, The BFPD can fieldbus devices (PROFIBUS PA device or FF H1 device), such as measuring instrument, sensor, actuator is connected to the main line of Fieldbus through the branch cable, its installation in the field instruments near branch cable up to 120 meters, usually 60 meters.
The BFPD series products are of three types: 101, 102, 103; each has two main lines of the interface of T1 and T2, 4 spur of X1, X2, X3, X4 interface port; waterproof casing with metal die-casting, protection grade is IP67, installation is simple and convenient, and has a ground terminal for NSPFD; with the BFPD products are 8 LED lights, indicating the operation state of port
Funcion
- Connection of field device (Profibus PA device or FF H1 device) for corresponding bus (PROFIBUS PA or FF H1)
- Automatic termination resistor (103) or a built-in switch-setting termination resistor (102, 101)
- Spur port fault · isolation (103, 102)
- Connection of isolated spue port after fault rectification (103, 102)
- 2 cable glands for the main line
