You can configure the module with STEP 7 (TIA Portal) and with a GSD fileThe following accessories are supplied with the module and can also be ordered separately
as spare parts:
● Front connector (push-in terminals) including cable tie
● Shield bracket
● Shield terminal
● Power supply element (push-in terminals)
● Labeling strips
● U connector
● Universal front door
For more information on accessories, refer to the system manual Automatmanual Distributed I/O System ET 200MP This section contains the block diagram of the module and outlines various connection
options.
For more information on front connector wiring and creating cable shields, etc., refer to the
"Wiring" section in the Automation System Distributed I/O System ET 200MP You can find additional information on compensating the reference junction temperature in
the function manual Analog value processingrecord in the section Structure of a data record for dynamic reference temperature
(Page 59).
Note
You may use and combine the different wiring options for all channelsThe power supply element is plugged onto the front connector for powering the analog
module. Wire the supply voltage to terminals 41 (L+) and 43 (M). The example in the following figure shows the pin assignment for voltage measurementAnalog digital converter (ADC)

Figure 3-8 Block diagram and pin assignment for grounded thermocoupThe module is set to voltage measurement type with measuring range ±10 V by default. You
need to reassign the module parameters with STEP 7 if you want to use a different
measurement type or range.
Deactivate the input if it is not going to be used. The module cycle time is shortened and the
interference factors that lead to failure of the module (for example, triggering a hardware
interrupt) are avoided.
