1.1 SI-Xx08 Introduction
Thank you for purchasing our SI-Xx08 Industrial EtherCAT Slave I/O
Modules which supports EtherCAT protocol. EtherCAT (Ethernet Control
Automation Technology) which is developed by BECKHOFF Automation is
a high-performance Ethernet-based fieldbus industrial network system. This
protocol which is standardized in IEC standard IEC61558 is suitable for
real-time automation applications.
All EtherCAT Slave I/O Modules can be connected by the network topologies
such as star, line, or ring. Our SI-Xx08 I/O modules are installed by daisy
chain connection which has the flexibility in devices installation and reduces
the costs of infrastructure and operations. For the power requirements, the
SI-Xx08 modules are designed for standard industrial unregulated 24 VDC
Power input. However, they accept any power unit that supplies power within
the range of +9 to +48 VDC. All the I/O modules have the isolated input and
output design which protects SI-Xx08 I/O modules against external
interference and environment. The EtherCAT Slave Controller has passed and
has been verified by the conformance test tool. The qualified EtherCAT
Master can connect with SI-Xx08 modules easily and can be applied for
various applications.

1. DC Power-In Interface
The “+VS” and “GND” pins are used for the power supply and apply to all types of
SI-Xx08 EtherCAT I/O modules. The valid power voltage range is from +9 to +48 VDC.
The “FGND” is Frame Ground. The SI-Xx08 module device can be connected to the
building structure which is connected to the functional earth. With this architecture, the
same reference potential can be provided to all EtherCAT I/O modules. Please see the

2. EtherCAT Interface
SI-Xx08 EtherCAT Slave I/O modules are equipped with two RJ45 EtherCAT Interface
ports. One is “IN” port which is EtherCAT signal input port that connects to EtherCAT
Master or the EtherCAT signal output port of previous EtherCAT Slave I/O Module. The
other is “OUT” port which is EtherCAT Signal output that connects to the EtherCAT
signal input port of next EtherCAT Slave I/O Module.
