sages
Internal supply
Via I/O bus
External supply
Via the terminals L+ (process voltage 24
V DC) and M (0 V DC); the M terminal is
connected to the M terminal of the CPU via
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 a removable 9-pin and 11-pin terminal block. 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 analog inputs:
