The electrical connections between the modules are made by an interface board screwed into
the housing. The main board is pushed into rear slot 1 and locked. It holds a 10--pin and a
14--pin terminal strip to which all inputs and outputs of the standard controller are connected.
Five other slots can be equipped with option modules if the number of terminals to the process
available in the standard controller are not sufficient for the planned task.
The basic device always has three permanently installed analog inputs (AE) with electronic po-
tential isolation which can be wired alternatively with standardized voltage signals (0/0.2 to 1 V
or 0/2 to 10 V) or current signals (0/4 to 20 mA). There are also four digital inputs (BE, 0/24 V)
and eight digital outputs (BA, 0/24 V, 50 mA) which can be used for different functions depend-
ing on the configuration.
The SIPART DR24 also has three analog outputs which can all supply a current signal from 0 to
20 mA or 4 to 20 mA and be assigned to different variables.
A short--circuit--proof L+--output (DC 24 V, 100 mA) is available for supplying transmitters.
The power supply unit is located in a fully enclosed metal casing and is screwed tightly to the
plastic housing of the controller.
Many applications can be implemented with the three permanently available analog inputs of
the standard controller alone. Two additional input modules can be inserted in slots 2 and 3 for
complex jobs or for the connection of other input signals. These input modules are available in
addition to for processing normalized current and voltage signals for the direct connection of
resistance thermometers Pt100 and all common thermocouples and resistance sensors or po-
tentiometers. In addition a module with three analog inputs (equipment as in the standard con-
troller) can be inserted in slots 5 and 6. This increases the number of inputs to a total of 11.
Slot 4 serves to accommodate an interface module (SES) with V.28 point-to-point output or
SIPART bus interface for serial communication with a master system. A PROFIBUS interface
module can be equipped optionally here.
The slots 5 and 6 can accommodate signal converters of different functions and can be
equipped optionally with modules for expanding digital inputs or digital outputs.
Following assemblies are possible:
2 relays
4 digital outputs/2 digital inputs
5 digital inputs
3 analog outputs/3 digital inputs
1 analog output with digital fault output (y

3 analog inputs
