Internal power supply
Via I/O bus
External power supply
Via the terminal L+ (process voltage 24 V DC). The negative
pole is provided by the I/O bus.
Connections
For a detailed description of the mounting, disassembly and connection of the
module, please refer to the System Assembly chapter
The connection is carried out by using removable 9-pin and 11-pin terminal blocks. These
terminal blocks differ in their connection system (spring terminals or screw terminals, cable
mounting from the front or from the side). The terminal blocks are not included in the module's
scope of delivery and must be ordered separately.
The following block diagram shows the internal construction of the digital outputs:
