Resideo RA832A1074 Switching Relay
The Resideo RA832A1074 Switching Relay is a specialized DPST industrial-grade control designed for hydronic systems requiring high-voltage switching from a low-voltage thermostat. Engineered for 240 Vac input, this unit features a 24 Vac coil rating and an integrated transformer, streamlining the installation by eliminating the need for external power supplies for the control circuit. The dual-pole configuration is purpose-built for versatile field applications: one pole handles line voltage loads such as circulating pumps, while the second pole is rated for low voltage or millivolt circuits, making it ideal for simultaneous zone valve and boiler firing control. The 2-wire control circuit ensures compatibility with standard electromechanical and electronic thermostats. Built with a rugged enclosure and a removable cover, the RA832A1074 provides reliable electromechanical relay performance for heavy-duty HVAC switching cycles, ensuring seamless hydronic heating control in residential and light commercial environments.
Key Benefits
- Dual-Pole Switching: DPST configuration allows for simultaneous control of a line voltage circulator and a low-voltage burner circuit.
- Integrated Transformer: Internal 24V transformer powers the thermostat circuit, reducing component count and labor time.
- Versatile Compatibility: Designed to interface with 2-wire thermostats and is suitable for both standard and millivolt systems.
- Contractor-Grade Housing: Includes a durable metal cover to protect internal components from dust and debris in mechanical rooms.
- Efficient Footprint: Compact design facilitates easy mounting on standard 4x4 junction boxes.
Common Questions
Can the RA832A1074 be used with a 120V power supply?
No, this specific model is rated for a 240 Vac input. For 120V applications, the RA832A1066 is typically required.
Does this relay support 3-wire thermostats?
The RA832A1074 is optimized for 2-wire control circuits. If using a 3-wire thermostat, additional wiring modifications or a different relay series may be necessary.
Is the secondary pole rated for high voltage?
One pole is dedicated to line voltage, while the other is specifically designed for low voltage or millivolt signals, preventing cross-voltage interference during switching.
