Firmware and hardware versions

This documentation refers to the firmware and hardware version that was applicable at the time the

documentation was written.

The module features are continuously improved and developed further. Modules having earlier production

statuses cannot have the same properties as modules with the latest status. However, existing properties

are retained and are not changed, so that older modules can always be replaced with new ones.

2 Product overview

2.1 Product group: EtherCAT Box Modules

EtherCAT Box modules are I/O modules for industrial controllers.

They comply with protection class IP67 and are intended for use outside the control cabinet in wet, dirty or

dusty industrial environments.

EtherCAT Box modules communicate with the controller via the EtherCAT fieldbus. They each have two

connections for EtherCAT communication and for the power supply:

• Feed

• Downstream connection

This enables the cabling of EtherCAT Box modules in a line structure:

• 1x protective cap for supply voltage input, M8, transparent (pre-assembled)

• 1x protective cap for supply voltage output, M8, black (pre-assembled)

• 10x labels, blank (1 strip of 10)

Pre-assembled protective caps do not ensure IP67 protection

Protective caps are pre-assembled at the factory to protect connectors during transport. They may

not be tight enough to ensure IP67 protection.

Ensure that the protective caps are correctly seated to ensure IP67 protection.

NOTE

Protect connectors against soiling!

Protect the connections against soiling during mounting.

Mount the module with two M3 screws on the fastening holes in the corners of the module. The fastening

holes have no thread.

Guidelines

Follow these guidelines to ensure IP67 protection:

• Mount plugs with the torque values specified below. Use a torque wrench, e.g. Beckhoff ZB8801.

• Seal unused connectors with protective caps.

• Ensure the correct seating of pre-assembled protective caps.

Protective caps are pre-assembled at the factory to protect connectors during transport. They may not

be tight enough to ensure IP67 protection.

3.2.1 Power supply

The EtherCAT Box is supplied with two supply voltages. The supply voltages are electrically isolated in the

EtherCAT Box.

• The control voltage U

S

is the supply voltage for:

◦ processor logic

◦ fieldbus logic

◦ analog inputs and outputs

• The peripheral voltage U

P

is the supply voltage for:

◦ External sensors: M12 sockets 1 and 2

◦ External actuators: M12 sockets 3 and 4

3.2.1.1 Connection

NOTE

Supply voltages can destroy EtherCAT interfaces

Connectors for supply voltages have the same design as connectors for EtherCAT. They are not protected

against mismating.

Avoid mismating.

Observe the color coding of the connectors:

Power supply: black

EtherCAT: green

Two M8 connectors at the low-end of the modules are used for feeding and routing the supply voltages:

• IN: left M8 connector for feeding the supply voltages

• OUT: right M8 connector for forwarding the supply voltages

Redirection of the supply voltages

The IN and OUT power connections are bridged in the module (not IP204x-Bxxx and IE204x). The supply

voltages U

S

and U

P

can thus easily be transferred from EtherCATBox to EtherCATBox.

NOTE

Pay attention to the maximum permissible current!

Pay attention also for the redirection of the supply voltages U

3.2.1.3 Power cable conductor losses M8

The ZK2020-xxxx-yyyy power cables should not exceed the total length of 15m at 4A (with continuation).

When planning the cabling, note that at 24V nominal voltage, the functionality of the module can no longer

be assured if the voltage drop reaches 6V. Variations in the output voltage from the power supply unit must

also be taken into account.

Fig.8: Power cable conductor losses

Example

8m power cable with 0.34mm² cross-section has a voltage drop of 3.2V at 4A.

3.2.2 EtherCAT

For connecting EtherCAT devices only shielded Ethernet cables that meet the requirements of at least

category5 (CAT5) according to EN50173 or ISO/IEC11801 should be used.

EtherCAT uses four wires for signal transmission.

Thanks to automatic line detection ("Auto MDI-X"), both symmetrical (1:1) or cross-over cables can be used

between Beckhoff EtherCAT.

Detailed recommendations for the cabling of EtherCAT devices can be found at

https://infosys.beckhoff.com/content/1033/ethernetcabling/index.html?id=1661412216745722148.

different color codes in circulation. The electrical properties of the cables have been retained when
