Omron 11Pin Relay DC 12V

Description

Omron MK3P-I 11-Pin Round Base Power Relay (DC 12V Variant) The Omron MK3P-I 12VDC is a heavy-duty, octal-style electromagnetic power relay built for dependable switching in industrial control circuits, automation systems, and low-voltage electrical panels. Featuring an 11-pin circular plug configuration, this 3PDT (Triple Pole Double Throw) relay uses a 12V DC control coil to safely isolate and toggle up to three completely independent electrical pathways at the same time. Key Features Contact Configuration: 3PDT (3 Form C: 3 Normally Open / 3 Normally Closed contacts). Coil Voltage: 12V DC (Direct Current), drawing standard control-level power to actuate the internal solenoid. Switching Capacity: Robustly rated to switch heavy electrical loads up to 10A at 250V AC or 10A at 28V DC. Visual Diagnostics: Housed in a transparent, dust-proof “ice-cube” casing with a mechanical flag indicator that physically tracks the armature’s position. 11-Pin Plug Layout: Standard octal circular pin array designed to withstand high vibration and ensure stable current delivery across all poles. Compatibility Guide The 12V DC variant of this 11-pin relay bridges low-voltage electronic controls with high-voltage industrial field gear. 1. Compatible Trigger Inputs Because this model utilizes a 12V DC coil, it is directly compatible with lower-voltage triggering systems: DC Power Supplies: Plugs seamlessly into 12V industrial control circuits or marine/automotive power networks. Embedded Microcontrollers: Can be driven via transistors or optocouplers from Arduino, Raspberry Pi, or custom PCB logic arrays. PLC Modules: Matches standard 12V DC transistor or relay output cards on Programmable Logic Controllers. 2. Compatible Base Sockets (Mounting) To avoid manual wiring or soldering directly to the round pins, this plug-in relay interfaces with standard track-mount bases: PF113A / PF113A-E Sockets: The industry-standard matching 11-pin round-base screw-terminal socket. It snaps directly onto a standard 35mm DIN rail, allowing field technicians to route and lock down raw field wiring securely using a standard flathead screwdriver. 3. Common Applications Low-Voltage Industrial Buffer: Acts as an electrical shield between delicate 12V logic control boards and high-voltage AC/DC industrial equipment. Three-Phase Line Switching: Allows a simple 12V signal to simultaneously switch or isolate all three legs of a small three-phase motor, pump, or industrial heating bank. Automotive & Marine Automation: Frequently integrated into heavy-duty 12V mobile environments (such as commercial boats, specialty trucks, and RV power distribution panels) to manage heavy auxiliary loads.
