The DE RHMY-2C-D is a general-purpose, plug-in electromagnetic relay featuring a DPDT (Double-Pole Double-Throw) contact configuration. Equivalent to the industry-standard MY2N series, this relay includes a built-in LED indicator to display the coil's operational status. It is designed for mounting on matching 8-pin sockets (such as the PYF08A) and is used for power switching, signal isolation, and automation control.

Specifications

• Coil Voltage: 220VAC (to 240VAC), 50/60Hz
• Contact Form: DPDT (2 Form C — 2 Changeover Contacts)
• Contact Ratings:
  • Resistive Load: 3A @ 240VAC
  • DC Load: 3A @ 28VDC
• Number of Pins: 8-pin plug-in terminal layout
• Indicator: Onboard LED (illuminates when the coil is energized)
• Dielectric Strength: 2,000VAC between coil and contacts

Key Features

• Dual Pole Configuration: Controls two completely independent electrical circuits simultaneously with a single control signal.
• Visual Status LED: Simplifies system troubleshooting by giving maintenance personnel immediate visual feedback when power is active on the coil.
• Clear Protective Casing: Housed in a transparent polycarbonate cover that allows for easy inspection of the internal mechanical contacts.
• Standard Plug-in Design: Easily drops into standard DIN-rail mount sockets, drastically reducing wiring complexity and downtime during replacement.

Common Applications

• Industrial Control Panels: Used to interface low-power controllers (like PLCs) with high-power industrial loads.
• Motor Control: Actuating small single-phase AC motors, pumps, or fans.
• HVAC Systems: Controlling dampers, valves, and sequencing elements in heating and cooling architectures.
• Signal Isolation: Isolating sensitive electronic logic circuitry from noisy, high-voltage field wiring.

Usage Tips

• Socket Requirement: Do not attempt to solder wires directly to the blade pins. Use a matching 8-pin relay base (typically a PYF08A socket) for safe DIN-rail implementation.
• AC Coil Behavior: Because the coil is rated for 220VAC, never apply DC voltage to it. DC voltage will cause excessive current draw, causing the coil to overheat and eventually burn out.
• Contact Arc Suppression: When switching highly inductive loads (like large motor contactor coils or solenoids), place an external RC snubber network across the relay contacts to mitigate arcing and prolong contact lifespan.
• Orientation Check: Ensure the relay is pushed completely into its socket and locked down using a retaining clip if the equipment is subjected to structural machine vibration.
