Dwyer Instruments TSF-4010 Thermocouple Limit Control

For high-performance thermal safety, the Dwyer Instruments TSF-4010 Thermocouple Limit Control provides critical over-temperature protection for gas-fired ovens, burners, and industrial processing equipment. This FM-approved temperature limit control is engineered for a 110 Vac power supply and supports versatile Type J, K, and S thermocouple inputs, offering a probe range up to 999°F depending on the sensor used. Its SPDT relay output is rated for 16 A at 240 VAC resistive, including a 1 HP motor rating for direct control of heavy-duty contactors or alarms. Field technicians can easily toggle between automatic and manual reset modes using the integrated front-panel button or via external contacts for remote operation. Featuring an IP64-rated front panel and a high-visibility 3-digit LED display, this control ensures reliable performance in demanding environments. Use the Dwyer TSF-4010 when you need a robust, panel-mounted digital limit switch to maintain strict safety parameters and prevent equipment damage from thermal runaway.

• Universal Compatibility: Accepts Type J/K/S input, allowing for standard sensor integration across different high-heat applications.
• Enhanced Safety: FM-approved limit control with a 16 amp SPDT relay output for industrial-grade protection.
• Flexible Operation: Features both internal front-panel reset and remote reset terminals for flexible mounting configurations.
• Durable Construction: IP64 (NEMA 3R) front panel rating provides significant resistance to dust and moisture ingress.
• Precision Monitoring: Accuracy of ±1% full scale with nonvolatile memory to preserve setpoints during power cycles.

How do I change between automatic and manual reset on the Dwyer TSF-4010?
The reset mode is selectable via the 10 internal parameters. You can perform a reset using the physical button on the faceplate or by wiring an external contact to the specified terminals for remote access.

What happens to my settings if the 110 Vac power is disconnected?
This thermocouple limit control utilizes nonvolatile memory, ensuring all configuration parameters and limit setpoints are retained even if supply power is lost.

Can I use this limit control with a 230V motor?
Yes, the SPDT relay is rated for 16 A at 240 VAC with a 1 HP rating, making it suitable for direct control of small motors or large resistive heating loads.
