Product Overview

The Turck MK31-111-LI/24VDC is a versatile modular I/O interface designed for seamless integration of sensors and actuators into industrial control systems. Part of Turck's MK30/40 series, this module combines signal conditioning, power distribution, and communication capabilities in a compact, DIN rail-mountable housing. It supports 24 V DC operation and integrates IO-Link (LI variant) for bidirectional data exchange with PLCs or Industry 4.0 ecosystems. The rugged polyamide housing (IP20/IP65 protection, depending on installation) ensures reliable performance in control cabinets or decentralized setups. With plug-and-play M12 connectors, the MK31-111-LI/24VDC simplifies wiring in applications ranging from factory automation to mobile machinery.

Key Technical Parameters
  • Input/Output Channels: 8 digital I/O channels (configurable as sinking/sourcing)
  • Communication Protocol: IO-Link v1.1 (LI variant) for device-level connectivity
  • Supply Voltage: 24 V DC (±10%) with reverse polarity and overload protection
  • Current Rating: 2 A per channel (max), 4 A total module current
  • Operating Temperature: -25°C to +60°C (-13°F to +140°F)
  • Protection Class: IP20 (housing) / IP65 (front face with connectors sealed)
  • Housing Material: Flame-retardant polyamide (UL94 V0)
  • Certifications: CE, UL, cULus, RoHS, and IEC 61000-6-2/6-4 (EMC)
  • Connectors: 12-pin M12 female ports for field devices and power
Typical Applications

The MK31-111-LI/24VDC is ideal for industrial environments requiring flexible I/O solutions:

  • Factory Automation: Centralizing sensor/actuator signals in conveyor systems or robotic cells
  • Process Control: Monitoring valves, pumps, or temperature sensors in chemical plants
  • Mobile Equipment: Distributing power and signals in agricultural or construction machinery
  • Packaging Lines: Integrating photoelectric sensors and pneumatic valves via IO-Link
  • Energy Management: Collecting data from smart meters or HVAC systems for SCADA integration

Its modular design allows daisy-chaining for scalable network expansion.

Competitive Advantages
  1. IO-Link Integration: Enables advanced diagnostics, parameterization, and firmware updates
  2. High Channel Density: 8 configurable I/O channels reduce hardware footprint and costs
  3. Robust Design: Polyamide housing and M12 connectors withstand vibration and dust
  4. Easy Configuration: Plug-and-play installation with pre-assembled cables
  5. Scalability: Modular expansion via Turck's MK series backbone components
Core Functionalities
  • Bidirectional Communication: Real-time data exchange via IO-Link Master (e.g., process values, diagnostics)
  • Short-Circuit Protection: Automatic shutdown of faulty channels to prevent system damage
  • LED Diagnostics: Per-channel status indicators (green/yellow) for quick troubleshooting
  • Hot-Swappable Modules: Replace or add modules without powering down the system
  • Dual Power Inputs: Redundant 24 V DC terminals ensure uninterrupted operation
