3.1 ES600 Measurement Modules
The ES6xx series comprises a range of advanced and powerful measurement
and interface modules. All modules are designed for use under harsh environ-
mental conditions and are therefore ideally suited for automotive use. This
applies both to the housings of the ES6xx series and all cable connections. The
ability of these modules to operate under a wide range of ambient tempera-
tures and power supply voltages further contributes to their suitability for auto-
motive applications.
The compact and rugged housings of the ES6xx series allow easy mounting
even under difficult installation conditions. By installing the modules close to
the signal source, it is possible to avoid long signal lines that would corrupt
measurement signals. The housings of the ES6xx series stack easily to build
larger blocks of units.
The measurement modules provide a high sampling rate with high resolution
and accuracy. The accuracy is guaranteed across A/D and Thermo Modulethe
entire extensive ambient temperature range.
The interface modules provide the connection to the popular bus systems used
in motor vehicles and to various emulator probes (ETK).
Each module is equipped with a powerful Ethernet interface that ensures high-
speed data exchange with the host PC.
A synchronization and power management module makes it possible to con-
nect several measurement and interface modules to one Ethernet interface on
the host PC. This synchronization and power management module also
ensures simultaneous sampling of all measurement channels—even in large
module networks. The periodic synchronization signal is superimposed onto
the Ethernet signals without affecting data transfer. This excludes the possibil-
ity of a phase shift between the individual signals, even when measurements
are taken from different modules.
All modules of the ES6xx series have an automatic power saving feature. For
this purpose, the modules are equipped with a link signal detector that is con-
trolled directly by the Ethernet interface. As soon as a device connected to the
ES650.1 starts to send link signals via the Ethernet interface, the module is

“awakened” from its power-saving standby mode and is ready for operation.
When it no longer receives any more link signals, the ES650.1 switches back
into standby mode automatically after a delay.
The modules are configured using the INCA’s graphical user interface (GUI).
INCA also provides you the functionality for data acquisition and data evalua-
tion.
3.2 ES650.1 A/D and Thermo Module
3.2.1 Overview
The ES650.1 is designed to measure analog input voltages and temperatures.
It provides you with eight channels for input voltages and eight channels for
temperature measurement using thermocouples.
Fig. 3-1ES650.1 A/D and Thermo Module
NOTE
The ES650.1 only switches from the power-saving standby mode to opera-
tion mode when it receives link pulses via the Ethernet interface. To ensure
that a connected PC sends link pulses, its Ethernet adapter must be properly
configured. A data transfer via the Ethernet interface automatically switches
the ES650.1 into operation mode.

The channels for analog input voltages have two input voltage ranges. The res-
olution is 16 bits, the inaccuracy is 2 mV in the 10 V range or 12 mV in the 60 V
range, depending on the input voltage.
The thermocouple channels have a resolution of 21 bits. You can use B-, E-, J-,
K-, N-, R-, S- and T-type thermocouples. The maximum measuring range is
-210 °C to +1,820 °C. Each thermocouple channel is fitted with a cold junction
compensation directly in the connector. This ensures accuracy even when the
housing is not heated uniformly. The thermocouples are galvanically isolated
from each other and from case ground.

3.6 Maximum Input and Common-Mode Voltages
The maximum input voltage between two inputs and the maximum voltage
between an input and case ground is 60 V DC / 30 V AC.
For an explanation of the maximum input and common-mode voltages, see the
illustration and example below.
Fig. 3-5Maximum input and common-mode voltages
All capacitors between the inputs (Uin+ and Uin-) and case ground have the
same capacity. The maximum voltage between any input and case ground is
60 V DC / 30 V AC.
Example
For the given input voltages Uinx, Uiny, Uinz and the common-mode voltage
UCMxy, the maximum allowed common-mode voltage UCMyz is to be calculated.
Uinx = 10 V
Uiny = 5 V
Uinz = 10 V
UCMxy = 15 V
max(Uinx + Uiny + Uinz + UCMxy + UCMyz) = 2 Uc = 60 V
10 V + 5 V + 10 V + 15 V + max(UCMyz) = 60 V
max(UCMyz) = 60 V - 40 V = 20 V

3.7 Measurement Accuracy
While measuring temperatures with thermocouples the total measurement
inaccuracy is determined by different parts. These parts are:
• Basic accuracy Tg
• Temperature drift of thermocouple inputs Td
• Inaccuracy depending on the internal resistance of the thermocouple Ti
• Inaccuracy of cold junction compensation Tcjc
• Temperature drift of cold junction compensation Tdcjc
The maximum total inaccuracy is the sum of all parts.
T = Tg + Td + Ti + Tcjc + Tdcjc
The amount of the parts depends on the type of thermocouple. The figures are
listed in table “Thermocouple Inputs” on page 33.
Two examples show you how to calculate the maximum total inaccuracy.
Example 1
A thermocouple of type K with an internal resistance Ri of less than 50  is
used to measure a temperature Tm of 200 °C (473.15 K; 392 °F) at an ambient
temperature Ta of 25 °C (77 °F).
Tg = ( | Tm - T0 | * 0.025 %) + 0.25 K
Tg = ( | 473.15 K - 298.15 K | * 0.025 %) + 0.25 K
Tg = 0.29 K
Td = 0.005 K/K * | Ta - T0 |
Td = 0.005 K/K * | 25 °C - 25 °C |
Td = 0.00 K
Ti = 0 because the internal resistance is less than 50 
Tcjc = 1 K
Tdcjc = 0.008 K/K * | Ta - T0 |
Tdcjc = 0.008 K/K * | 25 °C - 25 °C |
Tdcjc = 0.00 K
The maximum total inaccuracy is:
T = Tg + Td + Ti + Tcjc + Tdcjc
T = 0.29 K + 0.00 K + 0.00 K + 1 K + 0.00 K
T = 1.29 K
In this example the maximum total inaccuracy is determined by the inaccuracy
of the cold junction compensation.
