Beckhoff EL3162 | EtherCAT Terminal, Analog Input Module, 0-10V, 16Bit Resolution, 2Channel
1. Product Overview
EL3162 is standard EtherCAT analog input terminal manufactured by Beckhoff Germany, featuring 2 single-ended voltage input channels with 0~10V measuring range & 16-bit high-precision AD conversion. It collects analog voltage signals from on-site transmitters, displacement/level/pressure sensors, converts analog signals into digital data, then transmits real-time data to upper-layer PLC/IPC controller via high-speed EtherCAT fieldbus with galvanic isolation protection between signal side and system E-bus. Compact DIN-rail modular design allows free splicing with other EL-series EtherCAT terminals, serving as core signal acquisition component for decentralized industrial automation control system, fully compliant with EU CE & EEC certification requirements for European customs clearance.
2. Core Advantages & Key Features
- High Precision Measurement: 16-bit ADC resolution, full-scale measurement error＜±0.3%, internal input resistance＞200kΩ to avoid signal attenuation for stable voltage sampling.
- Integrated Distributed Clocks: Built-in EtherCAT Distributed Clock function to realize precise synchronous data acquisition for multi-axis linkage & high-speed automation equipment.
- Isolation & Anti-interference: 500V galvanic isolation between E-bus and input signal; standard 5kHz input filter + optional FIR/IIR digital filter to suppress industrial electromagnetic interference.
- Ultra-fast Conversion Speed: Single-channel conversion time only ~50μs, meets high-frequency real-time signal collection demand for high-speed production lines.
- Compact & Easy Wiring: 12mm narrow housing saves cabinet space; pluggable terminal wiring with channel status LED indicator for quick troubleshooting.
- Full Certification Compliance: Passed CE, UL, EAC certification, meets EN61000 EMC & EN60068 environmental standard, suitable for global export including EU & EAEU market.
- Limit Monitoring Function: Built-in over-range limit value monitoring, automatically feedback abnormal signal status to controller for equipment protection.
