Teplotní spínač H-TRONIC UTS 125 -55 až +127°C 1114680

Monitoring and controlling temperature precisely can be challenging in many industrial and DIY applications. The H-TRONIC UTS 125 temperature switch solves this by providing reliable switching based on temperature thresholds, with a wide measurement range and flexible configuration.

Who is it for

This device is ideal for technicians, hobbyists, and facility managers who need to automate heating or cooling systems, monitor process temperatures, or protect equipment from overheating. Its DIN rail mounting makes it suitable for control cabinets and electrical enclosures.

Main features

• Wide temperature range from -55°C to +127°C using an external DS18B20 sensor
• Internal sensor for ambient temperature from -10°C to +50°C
• Relay output with one changeover contact (SPDT), switching up to 5 A at 250 V AC
• 3-digit LED display with 14 mm digit height for clear reading
• Adjustable hysteresis from 0.1°C to 20.0°C to prevent rapid switching
• Selectable heating or cooling mode
• DIN rail mounting (TS35), 2 modules wide

Specifications

• Supply voltage: 12 V DC
• Temperature resolution: 0.1 °C
• Accuracy: ±0.5 °C at 25°C
• Sensor compatibility: DS18B20 (external), NTC (internal)
• Electrical connection: screw terminals
• Housing protection: IP20

Tips

For accurate external measurements, place the DS18B20 sensor at the point of interest and avoid thermal bridges. The hysteresis setting allows you to fine-tune the switching behavior to avoid rapid on/off cycles.
