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.

The firmware and hardware version (delivery state) can be found in the batch number (D-number) printed on
the side of the EtherCAT Box.

WW - week of production (calendar week)
YY - year of production
FF - firmware version

EtherCAT Box - Introduction

2 EtherCAT Box - Introduction

The EtherCAT system has been extended with EtherCAT Box modules with protection class IP67. 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 126x30x26.5 mm (hxw xd) 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 M8connectors.

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 M12connectors.

The EtherCAT modules cover the typical range of requirements for I/O signals with protection class IP67:

• digital inputs with different filters (3.0ms or 10μs)

• digital outputs with 0.5 or 2A output current

• analog inputs and outputs with 16bit resolution

• Thermocouple and RTD inputs

• Stepper motor modules

XFC (eXtreme Fast Control Technology) modules, including inputs with time stamp, are also available.

3.1 Introduction

Fig.4: EP2624-0002

4-channel relay output, 25 VAC / 30 V

The EP2624 EtherCAT Box has four relays each of which has a single contact. The relay contact is suitable
for use at up to 25VAC or 30VDC. The EtherCAT Box indicates its signal state by means of light emitting
diodes. The EP2624 has potential-free contacts. The power supply is looped through.

3.3 Scope of supply

Make sure that the following components are included in the scope of delivery:

• 1x EtherCAT Box EP2624-0002

• 2x protective cap for EtherCAT socket, M8, green (pre-assembled)

• 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.
