SIMATIC modules
We additionally use
SIMATIC
modules in the chro-
matograph as signal converters for analog and digi-
tal signals. The chromatograph can then, for
example:
Switch valves via digital outputs
Scan the switches of pressure monitors via digi-
tal inputs
Display results in the control room via analog
outputs
Calculate values from a scale with the analytical
result via analog inputs.
The following modules can be used in our chromato-
graphs:
32 digital outputs 24 V/0.5 A 6ES5 451-4UA12
16 digital outputs 24 V/2 A 6ES5 453-4UA12
16 digital outputs and
16 digital inputs 24 V/0.5 A 6ES5 482-4UA12
32 digital inputs 24 V 6ES5 430-4UA12
8 analog outputs 0 to 20 mA 6ES5 470-4UA12
8 analog outputs 4 to 20 mA 6ES5 470-4UC12
8 analog inputs 6ES5 460-4UA12
All modules occupy one slot in the chromatograph
computer, apart from the module 453 which requires
two slots.
IMPORTANT:
SIMATIC
-modules only function if they are
correctly addressed and if their enable input is
correctly connected. The following pages show
how you must wire the modules.
Inserting or removing modules
Only insert or remove
SIMATIC
modules with the chro-
matograph switched off. You thus avoid damaging the
modules. In addition,
SIMATIC
modules do not function
if they are inserted when the chromatograph is on.
Loosen the screw (1) on the front plug
Swing out the top of the front plug and lift out of
the bottom bearing (2)
Rotate locking screw (3) by 90°
Pull out the module using the handle (4). This
handle is hidden. It can be extracted from below
using a pointed object.
Install in the reverse order.
Electrical isolation
All inputs and outputs are electrically isolated from the
module power supply which is applied at the rear. The
inputs and outputs are nevertheless not electrically iso-
lated in the chromatograph because the 24 V comes
from the chromatograph power pack and all
SIMATIC
modules are connected to one another via their front
panels.
If electrical isolation is required, use a separate module
and provide an external voltage of 24 V. Individual
floating digital inputs or digital outputs can be im-
plemented using relays.
