1.1 Introduction
ICOP’s QEC RXXD series are standard industrial EtherCAT slave digital I/O modules, with
standalone isolated design on each channel to protect from harmful interference and
influences critical environment. The modules offer a wide variety of I/O channels that can be
intermixed between 4, 8, 12 and up to 16 I/O channels, also providing custom service to save
unnecessary components cost.
Comply with EtherCAT Conformance Test Tool (ET9400), the QEC-RXXD is qualified and can
be cooperated with the EtherCAT master systems for quickly implement in industrial
applications.
Capable up to 100 µs EtherCAT cycle time, as well as the Distributed Clock (DC) mode,
QEC-RXXD is aimed for high precision and synchronous applications requirement. Designed
with the up-to-date silicon components, it also reduces heat generation and extend product
life while also providing automatic internal status monitoring, including voltage, current and
operating temperature, to help provide effective carbon footprint tracking.
For Digital Input of QEC RXXD series, the maximum input frequency is 8KHz, it equipped with
various of optional features, including polarity separated digital input channel pins, input wire
break detection lines and up to 2500Vrms ESD isolation protection. And for Digital Output of
QEC RXXD series, the maximum frequency is also 8KHz, all channels are polarity neutral, with
up to 3750Vrms ESD isolation protection, and can drive up to 56Vdc@500mA.
QEC-RXXD offer users an easy way to update the firmware via FOE and features two
networks available for EtherCAT Cable Redundancy. The module status can be indicated by
LEDs for troubleshooting and verifying I/O status. Also provides flexible installation and
efficient I/O channel configurations for connectivity, reducing infrastructure and operating
costs, and can be deployed in network topologies such as star, line, or ring.
QEC-RXXD measures 107.45 x 77.4 x 30 mm, supports standard system operation from -20 to
+70°C and optional -40 to +85°C. It can be easily installed by Din Rail mounting kit and
features a European style terminal block that provides easy installation and removable wiring
terminals for easy deployment.
