The QEC-RXXA series is an EtherCAT analog I/O module that integrates Analog-to-Digital Conversion (ADC) and Digital-to-Analog Conversion (DAC) in a compact, industrial-grade design. It supports up to 8 slots of analog channels, allowing customers to freely configure analog input and analog output channel combinations to match application needs. The series has been verified with the EtherCAT Conformance Testing Tools (CTT), ensuring reliable integration into EtherCAT systems.
High-Accuracy Analog Input
The analog input channels support multiple voltage ranges (both bipolar and unipolar) to accommodate a wide variety of sensors and transducers. With a constant input impedance ≥ 1 MΩ and overvoltage protection up to ±20 V, the module delivers stable, durable performance in harsh industrial environments. A 16-bit ADC provides precise measurement, achieving ±0.2% FSR accuracy at 25°C.
Flexible Analog Output for Control and Signal Conditioning
For analog output, the QEC-RXXA series offers versatile signal conditioning with 0–24 mA current output and up to ±12 V voltage output options. Outputs are delivered at 16-bit resolution with ±0.2% FSR accuracy at 25°C, making the module ideal for driving actuators or interfacing with external control systems.
EtherCAT-Ready Design for Reliable Operation
The module supports firmware updates via File over EtherCAT (FoE) and includes dual RJ-45 ports to enhance network reliability and support EtherCAT cabling redundancy. Onboard LED indicators provide clear diagnostic and operational status for fast system checks and troubleshooting.
Compact, Installation-Friendly, and Topology Flexible
Designed to reduce infrastructure and maintenance costs, the QEC-RXXA series supports common EtherCAT topologies, including line, star, and ring configurations. With a compact footprint of 107.45 × 66 × 30 mm and an operating temperature range of -20 to +70°C (extended temperature options available), it fits well into space-constrained control cabinets. DIN-rail mounting further simplifies installation and service.
The QEC-RXXA44S is a representative model of the series—an excellent choice for applications requiring reliable, high-precision analog input and output within EtherCAT networks.
