Fig 2.17 Flywheel Diode Connection
Shunt Connector CN5 and DIP Switch S1
The shunt connector CN 5 and DIP switch S1 are described in this section.
Fig 2.18 Shunt Connector CN5 and DIP Switch S1
The functions of DIP switch S1 are shown in the following table.
Sinking/Sourcing Mode
The input terminal logic can be switched between sinking mode (0-V common) and sourcing mode (+24-V
common) if shunt connector CN5 is used. An external 24-V power supply is also supported, providing more
freedom in signal input methods.
