R845A1030 Switching Relay With Internal Transformer For DPST Hot Water Zone Control Or SPST Dual Load Switching Plug And Play Enclosed 24V Thermostat Relay For One Line Voltage Two Wire Systems

R845A1030 DPST Switching Relay with Internal Transformer
✔️ DPST switching for hydronic zone control with 24V thermostat drive

This enclosed switching relay provides DPST switching for hydronic hot water zone control or SPST control of two loads. It accepts 120V primary power and has an integral transformer that powers the 24V control circuit.

✅ DPST switching for hydronic zone control or two-load switching
✅ Internal transformer powers the 24V control circuit
✅ 120V primary power supply for line voltage operation
✅ One load must be line voltage; the other can be line or low voltage

💡 What is a switching relay with internal transformer used for in hydronic heating systems?

Short intro sentence: It lets a 24V thermostat power two loads from a built-in transformer.

• Handy for controlling one line voltage and one line or low voltage load
• Internal transformer provides low-voltage control power from 120V supply
• Enclosed, plug-and-play design for quick installation
