Omron 11Pin Relay DC 24V

Description

Omron MK3P-I 11-Pin Round Base Power Relay (3PDT) The Omron MK3P-I 11-Pin Round Base Power Relay is a heavy-duty, octal-style electromagnetic relay designed for robust switching in power distribution systems and industrial automation control panels. Utilizing an 11-pin circular plug configuration, this 3PDT (Triple Pole Double Throw) relay enables a single control input to safely toggle three independent electrical circuits at once. It features an integrated mechanical indicator window and a test button for manual contact validation during commissioning and troubleshooting. Key Features Contact Configuration: 3PDT (3 Form C: 3 Normally Open / 3 Normally Closed contacts). Switching Capacity: Heavy-duty rating handling up to 10A at 250V AC or 10A at 28V DC. Physical Architecture: Housed in a transparent “ice-cube” style enclosure with an integrated mechanical flag indicator that tracks contact position. 11-Pin Plug Layout: Standard circular (pin-style) configuration arranged in a traditional octal layout for secure, high-current connections. Safety Options: Many models include a latching lever or push-to-test button to force the contacts closed for rapid circuit testing without energizing the coil. Compatibility Guide The MK3P-I is an industrial mainstay for material handling, manufacturing lines, and heavy-duty motor logic systems. 1. Compatible Control Voltages (Coils) To ensure reliable latching without overheating the internal solenoid, match your panel’s trigger line to the exact coil rating stamped on the relay: DC 24V Coils: Commonly wired to industrial sensor arrays, safety circuits, and PLC digital outputs. AC 220V / 240V Coils: Standard choice for domestic/industrial utility grids and direct line-voltage sequence controls. AC 110V / DC 12V Coils: Deployed in marine power blocks, legacy automation frameworks, and custom heavy equipment builds. 2. Compatible Base Sockets (Mounting) This round-pin relay requires a matching circular receptacle socket block to facilitate secure wiring terminations on a control panel track: PF113A / PF113A-E Sockets: The standard matching 11-pin round-base screw-terminal socket. It clips directly onto a standard 35mm DIN rail, allowing raw control wires to be locked down using a standard screwdriver. 3. Common Applications Three-Phase Power Isolation: Ideal for simultaneously switching or isolating all three hot lines of a small three-phase motor or heating element circuit. Industrial Control Logic: Operates as a heavy-duty buffer relay between low-power logic controllers (PLCs) and high-current inductive loads (valves, large contactors, and pumps). Interlocking Safety Networks: Configured to cross-lock electrical systems, ensuring two conflicting industrial operations cannot run at the same time.
