IO Hvac Controls iO-CSRY120 Relay Kit 320819-301 This sensor is specifically designedThe iO CSRY120 is a specialized 120V relay kit engineered for seamless integration into higher voltage control circuits. As a veteran technician, you know that standard 24V thermostats aren't built to handle line voltage directly; this kit bridges that gap, allowing Temp Stat series or other low voltage controllers to safely manage 120V equipment. The relay is rated for a 15 Amp resistive load, making it ideal for fan coil units, unit heaters, and
