Resideo R8222U1006/B Relay

The Resideo R8222U1006/B Relay is a heavy-duty general-purpose switching relay engineered for high-demand HVACR applications. Operating on a 24V coil voltage, this DPST Normally Open (N/O) component provides reliable control for refrigeration equipment, air conditioning systems, and industrial automation. It features a laminated magnet construction for superior electrical efficiency and an untaped coil design to ensure cooler operation during continuous duty cycles. With molded terminal numbers and a circuit diagram printed directly on the housing, field wiring and diagnostics are streamlined for technicians. This Honeywell R8222U1006/B model is a direct plug-compatible replacement for industry-standard parts like the Steveco 90-340 and Mars 90340. Rated for up to 12A at 120VAC and 6A at 240VAC, it is versatile enough for pilot duty, power pole, and millivolt applications, offering a rugged solution for commercial and residential control circuits.
