Antunes 8742130013 DFL Dual Fan and Limit Control 24V with 2-SPST Relays

The Antunes 8742130013 is a dual function limit control that combines single-speed fan control with warm air high limit protection in one compact unit. Operating on 24V power, this control features two SPST (Single Pole Single Throw) relays and includes a 10-foot thermistor sensor for accurate temperature monitoring.

Key Features:

• 24V operating voltage for compatibility with standard HVAC control systems
• Dual relay design with both fan control and high limit safety functions
• Front panel adjustable potentiometers for Fan Limit and High Limit set points
• Adjustable hysteresis control to prevent short cycling
• Visual LED indicators for fan operation and high limit alarm status
• 10-foot thermistor sensor cable provides flexible installation options
• Configurable for single or dual thermistor operation via internal jumper
• PCB-mounted relays with N.O. and COM contacts (optional N.C. available)

This control is designed for HVAC applications requiring automated fan activation and high temperature limit protection. The fan relay activates based on the sensor temperature relative to the front panel Fan Limit setting, while the high limit relay provides safety shutoff when temperatures exceed the High Limit set point. Ideal for furnaces, heaters, and warm air distribution systems in commercial and industrial environments.
