4.10. [ac/dc Multi-board --- 16 Rev1]
4.10.1. Power, Open and Close terminal
① Power 24V ac/dc (dc + signal block)
② None
③ None
④ Open signal
⑤ Close signal
⑥ Power 24V ac/dc (dc – signal block)
4.10.2. [Chooses for Power input switch
① As using for ac mode,
#1 switch on, #2 switch off
② As using for dc mode,
#1 switch off, #2 switch on --16 Rev1]
NOTE: Don’t turn on both switch #1 and #2 at the same time that become a
reason of damage of the board
③ [Motor terminal block
Red wire of motor to connect #1
Black wire of motor to connect #2 --- 16 Rev1]
5. [Apply for optional communication protocol
5.1. ProfiBus Controller (PBC)
5.1.1. ProfiBus Controller is to provide multiple functions of communication by using 8 bit microprocessor
and Profibus Controller.
5.1.2. Generate long-life contacts to operate actuator in direct or reverse with semiconductor device for
open and close by using data from remote controller.
5.1.3. Provide the user actuator status information to confirm if Profibus is working correctly as the user
want.
5.1.4. Max. transmission speed is 12Mbit/sec
5.1.5. Easy to switch between PCU type and ON-OFF type.
5.1.6. Provide System Redundancy by using dual port and high reliability
5.1.7. LED lamps provide the status of actuator.
5.1.8. Application
