2.1 EtherCAT Box - Introduction
The EtherCAT system has been extended with EtherCAT Box modules with protection class IP67. Through
the integrated EtherCAT interface the modules can be connected directly to an EtherCAT network without an
additional Coupler Box. The high-performance of EtherCAT is thus maintained into each module.
The extremely low dimensions of only 126x30x26.5 mm (hxw xd) are identical to those of the Fieldbus
Box extension modules. They are thus particularly suitable for use where space is at a premium. The small
mass of the EtherCAT modules facilitates applications with mobile I/O interface (e.g. on a robot arm). The
EtherCAT connection is established via screened M8connectors.
Fig.1: EtherCAT Box Modules within an EtherCAT network
The robust design of the EtherCAT Box modules enables them to be used directly at the machine. Control
cabinets and terminal boxes are now no longer required. The modules are fully sealed and therefore ideally
prepared for wet, dirty or dusty conditions.
Pre-assembled cables significantly simplify EtherCAT and signal wiring. Very few wiring errors are made, so
that commissioning is optimized. In addition to pre-assembled EtherCAT, power and sensor cables, fieldconfigurable connectors and cables are available for maximum flexibility. Depending on the application, the
sensors and actuators are connected through M8 or M12connectors.
The EtherCAT modules cover the typical range of requirements for I/O signals with protection class IP67:
• digital inputs with different filters (3.0ms or 10μs)
• digital outputs with 0.5 or 2A output current
• analog inputs and outputs with 16bit resolution
• Thermocouple and RTD inputs
• Stepper motor modules
XFC (eXtreme Fast Control Technology) modules, including inputs with time stamp, are also available.

2.2 EP9214 - Introduction
Product overview
Fig.4: EP9214
Power distribution for EtherCAT Box (24VDC)
The EP9214-0023 enables connection of four power supply branches. In each branch the current
consumption for the control voltage US and the peripheral voltage UP is monitored, limited, and, if necessary,
switched off.
The power distribution is supplied via a 7/8" connector with up to 16A (per voltage supply US/UP). Several
modules can be configured in a cascade arrangement. In the event of a short-circuit in one of the four
outputs, the affected output is switched off. The supply for the other branches remains active. The switch-off
and control is done in such a way that the input voltage does not fall below 21V or other modules are going
down, caused by undervoltage.
During startup consumers with large capacities can be added without problem.
The master can read diagnostic messages from the individual channels via the EtherCAT interface.
Independent switching of individual consumer branches is also possible via the EtherCAT master.
In delivery state the eight outputs of the box (4 times Us, 4 times Up) are activated to enable operation
without EtherCAT.
After an error caused the switch off of a channel, this channel remains switched of when you try to switch it
on again and has to be set back actively by the EtherCAT master or a hardware reset at the box (lower M8
socket).

Power distribution for EtherCAT Box (24VDC) with data logging
The EP9224-0023 enables connection of four power supply branches. In each branch the current
consumption for the control voltage US and the peripheral voltage UP is monitored, limited, and, if necessary,
switched off.
The power distribution is supplied via a 7/8" connector with up to 16 A (per voltage supply US/UP). Several
modules can be configured in a cascade arrangement. In the event of a short-circuit in one of the four
outputs, the affected output is switched off. The supply for the other branches remains active. The switch-off
and control is done in such a way that the input voltage does not fall below 21 V or other modules are going
down, caused by undervoltage.
During startup consumers with large capacities can be added without problem.
The master can read diagnostic messages from the individual channels via the EtherCAT interface.
Independent switching of individual consumer branches is also possible via the EtherCAT master.
In delivery state the eight outputs of the box (4 times Us, 4 times Up) are activated to enable operation
without EtherCAT.
After an error caused the switch off of a channel, this channel remains switched of when you try to switch it
on again and has to be set back actively by the EtherCAT master or a hardware reset at the box (lower M8
socket).
Additional to this basic functionality that is also provided by EP9214, the EP9224 displays the voltage values
of PowerIn supply and all current values of inputs and outputs within the process data.
The box has got an internal log file, that is writing the system values continuously into a ring buffer. This data
logging has to be activated at the startup.
In error case it is stopped, so a history of the system parameters from before the error case can be read out.
This enables a much quicker error localization.

3.1.2 Mounting
EP9214 modules are mounted using two M3 bolts in the mounting holes located in the corners or using two
M4 bolts in the centrally located mounting holes.
The bolts must be longer than 15 mm. The mounting holes in the modules have no thread.
Protect connectors against soiling
Protect all module connections from soiling during installation!The protection classes IP65,
Note
Note
Note when mounting that the overall height is increased further by the fieldbus connections. See the
Accessories section
IP66, IP67 (in accordance with EN 60529) are ensured only if all connectors are wired or
sealed! Unused connectors must be sealed with suitable protective caps (see Beckhoff catalogue for connector sets and protective caps)!
Cooling plate
The EP9214 module has a cooling plate on the underside. For the effective dissipation of
the resultant power loss, the box must be bolted to a metal base, e.g. the machine bed, if
possible making contact over the entire surface.A temperature-related automatic switch-off
of the box can occur if care is not taken to ensure that the power loss from the module is
dissipated via the cooling plate. A corresponding temperature error bit is then set!

For unification the prevalent cables ZB9030, ZB9032 and ZK1090-3xxx-xxxx this means
the pre assembled cables with M8 connectors were changed to the colors of EN61918 (yellow, orange, white, blue).So different color coding exists. But the electrical properties are
absolutely identical.

3.3.4 Power cable conductor losses
The ZK2020-xxxx-yyyy power cables should not exceed the total length of 15m at 4A (with continuation).
When planning the cabling, note that at 24V nominal voltage, the functionality of the module can no longer
be assured if the voltage drop reaches 6V. Variations in the output voltage from the power supply unit must
also be taken into account.

3.3.6 Conductor losses
In the case of the power cables ZK2030-xxxx-yyy, a total length of 15m should not be exceeded at 16A.
When wiring, note that with a rated voltage of 24V the function of the modules can no longer be guaranteed
from a voltage drop of 6V. Variations in the output voltage from the power supply unit must also be taken
into account.

Alternatively, larger cable cross-section can be used, e.g. 2.5mm2.
3.3.7 Power outputs
The supply voltages are output via four 4-pole M8 sockets in the lower third of the modules (1, 2, 3 and 4).

Mounting and cabling
Control voltage Us: 24V
Power is supplied to the fieldbus, the processor logic, the inputs and the sensors from the control voltage Us
(24VDC). The control voltage is electrically isolated from the fieldbus circuitry.
Peripheral voltage Up: 24V
The peripheral voltage Up (24VDC) supplies the digital outputs; it can be brought in separately. Hence, if the
load voltage is switched off, the fieldbus function as well as the supply and function of the inputs are
retained.

Electrical isolation
The grounds of the control voltage (GNDs) and peripheral voltage (GNDp) are electrically isolated from each
other in order to ensure the electrical isolation of the peripheral devices on Up from the control voltage.
The electrical isolation can be nullified
If you connect digital and analog EtherCAT Box Modules directly to one another via four-

3.5 Monitoring and reset contacts
The EP9214 has a monitoring contact (signal contact) and a reset contact. These contacts are fed out via an
M8 plug and an M8 socket.
The contacts of this M8 plug and M8 socket are wired together 1:1.
