Description
Siemens AG Dk-Nr. 232241 Edition 05.95 3
SIMADYN D Hardware User Manual
1. Description
The external EA12 module is used in the SIMADYN D system for outputting analog voltage signals
(-10 to +10V, accuracy: 14 bits or 1mV).
The addresses of these analog outputs are assigned by a programmable address decoder dependent
on the slot.
The EA12 module has 8 channels. The signal outputs are routed to the 20-way ribbon cable
connector X5. In addition to the 8 signals there is one ground terminal for each and, in addition, two
ground and two shield pins.
The signals can also be tapped at the double test sockets (dia. = 2.3 mm, one socket each for signal
and ground) e.g. on system startup.
The outputs can be loaded with up to 10 mA and are proof against short circuit up to a period of 120
sec.
Caution: the total signal load at connector X5 and the associated double test socket must not exceed
10 mA.
The output format for the individual channels can be configured. This is done by specifying a
multiplication factor in powers of 2 (extra for each channel).
The 50-pin ribbon cable connector X6 can be ignored, if at all available on the frontplate.
2. Module construction
- 1 plug-in station (corresponds to 1 1/3 SPS )
- SIMADYN D local bus connection
- Programmable address decoder (PAD) with module identification
- 8 analog output channels with D/A converters, -10 to +10 V, 10 mA, 14-bit accuracy (corresponding
to 1 mV)
- Connection option for KO via 2.3 mm test sockets

Notes for the user
4Edition 05.95 Siemens AG Dk-Nr. 232241
SIMADYN D Hardware User Manual
3. Notes for the user
The external EA12 module can be used both in all SIMADYN D subracks, in each connected to the
local bus. Each module takes up one plug-in station in the subrack.
The module can only function properly when it is screwed down in position
in the subrack (also during commissioning).
If the module is plugged onto an adapter, the frontplate (or even better, one of the two metallized
frontplate end pieces) must be connected to chassis via a short lead in order to have the shield
potential at X5/17/18.
Because of the type of power supply module used (switched-mode power supply), noise with voltage
spikes of up to 100 mV can be measured at the analog outputs. This is caused by surges/dips on the
M (0V reference potentials) bus and can be eliminated by installing an input filter at the signal
destination and keeping the given min. load (see technical data).
The eight output voltages of the module are adjusted for minimum offset and correct gain at an
ambient temperature of about 20°C. The offset determines how high the output voltage is for a
software value corresponding to 0 V. The gain adjustment however determines how high the output
voltage is for a software valu&e corresponding to ±10 V.
The two potentiometers required per output for this purpose have not been locked so that any
necessary adjustments can be made later in operation (ambient temperature, accuracy
specifications). The guide value for temperature sensitivity is ±240 uV at a temperature change of ±
1 deg.
The following table shows the assignment of potentiometers (-Rxx) to outputs:
EA12 outputs Connector Offset Gain
Output 1 X5 A -R49 -R46
Output 2 X5 B -R55 -R52
Output 3 X5 C -R61 -R58
Output 4 X5 D -R67 -R64
Output 5 X5 E -R73 -R70
Output 6 X5 F -R79 -R76
Output 7 X5 G -R85 -R82
Output 8 X5 H -R91 -R88
Before adjustment the module must have reached operation temperature (min. 2 minutes with
operation voltage).
When making adjustments, always start with the offset. To do this, the respective output should be
set to zero volts (software). The deviation of the output voltage from the desired zero volts is
corrected by turning the setting screw of the appropriate offset potentiometer. Rotation in the
clockwise direction changes the output voltage in the direction of +10 V.
When the offset adjustment has been made, the gain is adjusted with a software value of +10V at the
respective output. Deviation of the output voltage from the desired 10 V is corrected by turning the
adjusting screw of the respective gain potentiometer. Rotation against the clockwise direction
changes the output voltage in the direction of -10 V.
The analog outputs are connected via the SE7.1 interface module, which is snapped onto the
mounting rack. Another connection can be made by the SE40 interface module (one-to-one
connection of the ribbon cable connector pins to screw-type terminals).

Connector X5 on the output module and connector X1 on the interface module are interconnected by
a 20-way ribbon cable (Recommended: SC12 ribbon cable with twisted pairs).
The appropriate circuit diagram is shown in figure 1, appendix.
The SE7.1 interface module has a screw-type terminal for signal, ground and shield for each channel;
the shield is not connected to the SIMADYN D chassis potential.

8. ECB instructions
Components which can be destroyed by electrostatic discharge (ECB)
Generally, electronic boards should only be touched when absolutely necessary.
The human body must be electrically discharged before touching an electronic board. This can be
simply done by touching a conductive, grounded object directly beforehand (e.g. bare metal cubicle
components, socket outlet protective conductor contact.
Boards must not come into contact with highly-insulating materials - e.g. plastic foils, insulated
desktops, articles of clothing manufactured from man-made fibers.
Boards must only be placed on conductive surfaces.
When soldering, the soldering iron tip must be grounded.
Boards and components should only be stored and transported in conductive packaging (e.g.
metalized plastic boxes, metal containers).
If the packing material is not conductive, the boards must be wrapped with a conductive packing
material, e.g. conductive foam rubber or household aluminum foil.
The necessary ECB protective measures are clearly shown in the following diagram.
a = Conductive floor surface d = ECB overall
b = ECB table e = ECB chain
