🎯 Purpose:
The iR-DI16-K module from Weintek’s iR series is designed for collecting digital signals from push buttons, switches, sensors, and other equipment in automation systems. It is used as part of distributed I/O systems and can be connected via an iR series communication module (e.g., iR-ETN, iR-COP) or directly as a digital input module to the cMT-CTRL01 controller running CODESYS.

⚙️ Technical Specifications:

• 🔌 Input channels: 16 digital inputs (Sink or Source)
• ⚡ Nominal input voltage: 24 V DC (−15% … +20%)
• 📥 Input current: ~5 mA per channel
• ⏱ Response time: ≤ 5 ms
• 🛡 Galvanic isolation: between input channels and the module’s internal circuit
• 📦 Connections: removable terminal blocks for easy wiring
• 🔋 Power consumption: ~83 mA (from internal bus)
• 🌡 Operating temperature: 0…+55 °C
• 📐 Dimensions: 30 × 109 × 81 mm
• ⚖️ Weight: approx. 110 g
• 📏 Protection class: IP20, DIN-rail mounting

💡 Functional Features:

• Signal acquisition — receives digital signals from push buttons, limit switches, presence sensors, emergency signals, etc.
• System scalability — can be combined with other iR series modules (analog input/output, relay modules, high-speed modules).
• Direct integration with cMT-CTRL01 — works as a digital input module for CODESYS projects, enabling scalable PLC solutions.
• Integration — operates within PLC/HMI/SCADA systems via iR-ETN communication modules (Ethernet: Modbus TCP, EtherNet/IP) or iR-COP (CANopen).
• Reliability — galvanic isolation of inputs ensures protection against interference and overloads.
• Status indication — LEDs on the front panel for each channel allow real-time monitoring of input states.
• Ease of installation — compact housing and removable terminals ensure fast and convenient wiring.
