🎯 Purpose:
The iR-ETN40R is a compact Ethernet-based I/O module that serves as a gateway for Modbus TCP Server and EtherNet/IP Adapter networks.
The device integrates into the iR series and provides:

• 📡 connection of both high-speed and standard digital signals,
• ⚙️ flexible I/O expansion,
• 🛡️ protection and continuity of automation systems.

⚙️ Main Technical Specifications:

• 🔗 Communication interfaces: Modbus TCP, EtherNet/IP, 10/100 Mbps, up to 8 TCP connections.
• 🔌 Digital inputs: 24 (20 standard + 4 high-speed up to 20 kHz, PNP sink/source).
• ⚡ Digital outputs: 16 relay channels (2A/channel, up to 8A total), isolated.
• 🛑 Special functions:
  • “Stop Output” — instant shutdown of outputs in case of an emergency.
  • “Pulse Capture” — registers pulses shorter than 1 CPU cycle.
• 📦 I/O expansion: up to 16 additional iR modules (+224 inputs, +112 outputs, up to 64 analog channels).
• 💡 Indicators:
  • ENET (green — operating, red — error),
  • IO (green — module status, red — error).
• 🔋 Power supply: 24 V DC (−15% / +20%), consumption — 255 mA nominal, 540 mA max.
• 🌡 Operating temperature range: −10…+60 °C.
• 📐 Design: DIN-rail housing, IP20, dimensions 64×109×81 mm, weight ~0.27 kg.

💡 Functional Features:

• 🔗 Flexible connectivity — support for Modbus TCP and EtherNet/IP for easy integration with PLC/HMI/SCADA.
• 📈 Powerful scalability — up to 16 additional iR modules to expand I/O capacity.
• 🛡 Safety — dedicated stop input and pulse capture function increase reliability in critical applications.
• 🖥 Ease of configuration — support for EDS/XML files for EasyBuilder Pro and CODESYS.
