Product Overview
The Turck MS25-UI/24VDC is a versatile, modular signal conditioner and isolation barrier designed for safe and reliable signal transmission in industrial automation systems. Part of Turck’s MS25 series, this device provides galvanic isolation between field devices (e.g., sensors, transmitters) and control systems, protecting against ground loops, electromagnetic interference (EMI), and voltage surges. Its compact, DIN rail-mountable design (EN 60715) ensures easy integration into control cabinets or distributed I/O stations. The MS25-UI/24VDC operates on a 24 V DC power supply and supports universal analog input signals (4–20 mA, 0–10 V), making it ideal for process control, machinery, and hazardous environments.
The device features a robust polycarbonate housing with IP20 protection, suitable for indoor applications. Compliance with UL 61010, CE, and RoHS standards guarantees global safety and environmental compliance.
Key Technical Parameters
The MS25-UI/24VDC is defined by precision-engineered specifications:
- Input Signals: 4–20 mA, 0–10 V DC (configurable via DIP switches).
- Output Signals: Isolated 4–20 mA, 0–10 V DC (user-selectable).
- Isolation Voltage: 1500 V AC (input-to-output, input-to-power).
- Power Supply: 24 V DC (±10%), 85–264 V AC (universal input optional).
- Accuracy: ±0.1% of full scale for high-precision signal conditioning.
- Temperature Range: -20°C to +60°C (operational), -40°C to +85°C (storage).
- Response Time: <50 ms for real-time signal processing.
- Certifications: CE, UL 61010-1, RoHS, and IEC 61326-1 (EMC).
These parameters ensure reliable performance in high-noise industrial environments.
Primary Applications
The MS25-UI/24VDC is critical in industries requiring signal integrity and isolation:
- Process Control: Interfaces pressure transmitters, flow meters, and temperature sensors in chemical and pharmaceutical plants.
- Manufacturing: Connects load cells, encoders, and analog sensors in automotive assembly lines.
- Energy Management: Isolates signals from solar inverters, wind turbines, and battery monitoring systems.
- Water Treatment: Safeguards pH and conductivity sensors in harsh, corrosive environments.
- HVAC Systems: Transmits signals from thermostats and humidity sensors to building automation controllers.
Its galvanic isolation also suits applications in explosive atmospheres when paired with intrinsic safety barriers.
Competitive Advantages
The MS25-UI/24VDC outperforms standard signal conditioners through innovative design:
- Universal Input Flexibility: Configurable for multiple analog signal types, reducing inventory complexity.
- High Immunity to Noise: Shielded electronics and galvanic isolation ensure stable data transmission.
- Tool-Free Configuration: DIP switches and plug-and-play terminals simplify setup.
- Compact Footprint: Space-saving DIN rail design optimizes control cabinet space.
- Global Compliance: Meets UL, CE, and RoHS standards for worldwide deployment.
These features minimize downtime, enhance accuracy, and reduce maintenance costs.
Functional Features
The MS25-UI/24VDC delivers advanced functionality for industrial automation:
- Diagnostic LEDs: Real-time status indicators for power, input, and output signals.
- Reverse Polarity Protection: Safeguards against wiring errors.
- Overload Protection: Auto-reset functionality for short-circuit and overvoltage conditions.
- Plug-and-Play Wiring: Spring-clamp terminals support 0.2–2.5 mm² conductors.
- Scalability: Integrates with Turck’s modular I/O systems for expandable architectures.
Combined with Turck’s rigorous quality assurance, the MS25-UI/24VDC is a trusted solution for engineers prioritizing signal integrity, safety, and compliance in complex automation systems.
