2.2.1 Description of the block circuit diagram of modules
The DLX has a modular design. It consists of the following modules:
•
Power supply module
Converts the external auxiliary voltage (85VAC to 265VAC or 60VDC to
270VDC) into the internal device voltages (5VDC and 12VDC).
•
Connection module
Input pulse signals and control signals are galvanically isolated from the
process via input modules and connected to the processor module. Pulse
output signals and control output signals are serviced via the relay module
and an output module.
•
Processor module
The processor module controls all functions of the DLX. Apart from the mi-
cro controller it contains the internal program and data memory, a real time
clock and capacitors to bridge power failures. The displays and the keypad
are also connected to the processor module.
•
Display module
Stored data can be displayed via the LC-Display. The LED display shows
the status of individual process signals. Commands to the micro controller
are entered via the keypad. The program protection switch, which is used
to protect the parameters of the DLX from alterations, is located on the in-
side of the display module.
