The fieldbus dependent I/O module consists of
•the base module allows prewiring of the fieldbus, power supply, and sen-
sor/actuator connections.
•the plug-in electronic module contains the processing unit, the fieldbus
interface module, and the input and output circuits.
The electronic and base modules are supplied separately packed.

2.1 Base Module
The base module is the interface for all external wiring, including the fieldbus,
power supply, and sensor/actuator connections. A multi-conductor connector
links the external wiring to the plug-in electronic module.

The electronic module can be extracted by pressing the 4 latches and simulta-
neously pulling it from the base module.
4.1.3 Marking Label
The plastic marking label can be removed from the mounting points by ap-
plying slight finger force. To accomplish this, slide the label from one side
such that the label bends.
Insert the label by proceeding in the reverse order.

Abb. 4-5: Setting of the station address g1x2304x
1Address selection:
Switch „x1“ determines the units digit of the address.
Switch „x10“ determines the tens digit of the address.
With the unpermissible address 0 the station use the address 126.
The station address is taken over by the I/O module after power-on. Changes
during the operation have no effect.
4.2 Electrical Installation
4.2.1 General
ESD (Electrostatic Discharge)
The components are equipped with electronic components susceptible to be
destroyed when exposed to electrostatic load. Therefore, when handling these
components, ensure proper grounding of the surrounding objects and persons
(workplace, packing). Avoid contact with electrically conductive components,
e. g. the pins of a plug.
All connecting terminal blocks for the supply voltages and sensor and actuator
connections are equipped with CAGE CLAMP®connectors.
These CAGE CLAMP®connectors are suitable for fine-stranded and solid
conductors. When using ferrules, select the next smaller nominal cross section
for the conductor.

Fieldbus Dependent I/O Module
PROFIBUS DP
The WAGO-I/O-SYSTEM 752 requires a 24 V DC supply.
The sensors supply voltage is short circuit protected by means of the plug-in
fuse F1 (TR 5 / 250 V / 6.3A T).
Note
Use UL-Recognized fuse only
The supply voltage for the outputs can be fed through the module, or sourced
separately.

Two carrier rail contacts are provided on the underside of the base module to
ensure electrical contact between the grounded carrier rail and the I/O module.
The contacts are directly connected to the terminal block.
Attention
Ensure that solid contact is made between the carrier rail contacts on the un-
derside of the base module and the carrier rail itself.
The carrier rail must be grounded.

4.2.2 Connection of the Module Supply Voltage
The connection of the module supply voltage and earth ground is made on
terminal blocks carrying the following labeling:
•24 V (red terminal block)
•0 V (blue terminal block)
•(green terminal block)
Connection of earth ground to the base module’s ground terminal is required
for reliable module operation.
4.2.3 Connection of the Input Signals
The input signal connection group is identified by the imprint “INPUT” on the
base module. Three terminals are available for each digital input. The termi-
nals for one input are shown superimposed.

4.2.4 Connection of the Output Supply Voltage
The supply voltage for the two output groups of 8 connections each can be
provided either internally using the supply voltage for the module, or exter-
nally from a separate power source. The base modules are provided with two
sets of terminal blocks in the middle row of the output terminals. The left-
hand terminal of each set carries the 24VDC module power, while the right-
hand terminal provides a connection point for the output supply voltage.
The base modules are shipped with jumpers installed in each of these termi-
nals, connecting 24VDC module power to connection point for the output
supply voltage.
