Honeywell RP418A1065 Relay

The Honeywell RP418A1065 is a heavy-duty electric-pneumatic relay designed to seamlessly bridge high-voltage electrical circuits with pneumatic control systems. Operating at 480V/440V (50/60 Hz), this surface-mounted solenoid valve is engineered for demanding industrial environments where reliable interlocking is mandatory. It functions as a versatile diverting relay, selector relay, or stop-and-bleed valve, providing contractors with multiple configuration options in a single unit. With a maximum safe operating pressure of 50 psi and a 0.075 Cv capacity, it ensures precise air handling for components like the MP516A actuator or VP516C valve. The integrated junction box and 15-inch leads simplify field wiring, while the 1/4-inch barbed fittings ensure secure pneumatic tubing connections. This unit is the professional standard for replacing legacy equipment, including the 2368-406, AL-140, and AL-185 models, maintaining system integrity without requiring extensive piping modifications.

• High-Voltage Compatibility: Specifically designed for 480V and 440V applications, eliminating the need for step-down transformers in many industrial control panels.
• Universal Mounting: The rugged design allows for surface mounting in any orientation, facilitating easy installation in tight mechanical rooms or crowded control cabinets.
• Multi-Purpose Logic: Easily configurable for use as a selector relay or a stop and bleed valve to meet diverse sequence-of-operation requirements.
• Direct Interlock: Provides a reliable physical interface between electrical signals and pneumatic actuators, ensuring safe and predictable system responses.
• Standardized Connections: Features 1/4-inch barbed pneumatic connections that match existing polyethylene tubing for rapid field replacement.

Can the RP418A1065 be used to replace the newer RP419 series?
While the RP418A1065 is a robust predecessor, the RP419A1065 is its modern equivalent. When replacing one with the other, verify the maximum pressure ratings, as legacy RP418 models often handled up to 50 psi, whereas some newer versions may have different specifications.

What is the port logic for this relay?
When energized, ports 1 and 3 are connected while port 2 is blocked. When de-energized, ports 2 and 3 are connected and port 1 is blocked. This dual-state operation allows for flexible diverting relay applications.

Does this unit include the electrical housing?
Yes, this model comes equipped with a built-in junction box (splice box) and 15-inch lead wires, ensuring it meets code requirements for high-voltage terminations in a commercial setting.
