3.6.4 Implementation and Cable Connection of Fieldbus
Communication Module ALF111
This section describes the implementation and cable connection of the Foundation Fieldbus
Communication Module ALF111.
Foundation fieldbus H1 (Low Speed Voltage Mode) is called Foundation fieldbus, Fieldbus, H1
Fieldbus, FF, or FF-H1 in this manual.
Example of Implementation of Fieldbus Communication Module
ALF111
To connect Fieldbus using the ALF111, the power supply unit for the Fieldbus must be prepared
as shown below.
The example of the implementation and the wiring of the ALF111 is shown below.
For the implementation of the ALF111 and the relevant devices, follow the implementation
conditions for the devices. 1 U (unit) = 44.45 mm.
