Round Relay Base 11pin

Description

Omron MK3P-I 11-Pin Round Base Power Relay (AC 220V/240V Variant) The Omron MK3P-I AC220/240 family includes a heavy-duty, octal-style electromagnetic power relay designed for multi-circuit mains switching in demanding industrial environments, automation panels, and processing plants. Utilizing an 11-pin circular plug configuration, this 3PDT (Triple Pole Double Throw) relay relies on a mains-level AC 220V to 240V control coil to safely isolate and manage up to three independent high-current electrical pathways at the same time. Key Features Contact Configuration: 3PDT (3 Form C: 3 Normally Open / 3 Normally Closed contacts). Coil Voltage: 220V to 240V AC (Alternating Current), matching standard facility mains lines and utility grids. High Switching Capacity: Robustly rated for heavy electrical draws up to 10A at 250V AC or 10A at 28V DC. Visual Diagnostics: Enclosed in a transparent, dust-proof “ice-cube” casing featuring a mechanical flag indicator that shifts physically into position when the internal solenoid forces the contacts closed. 11-Pin Plug Layout: Standard octal circular pin array designed to withstand high-vibration environments while ensuring stable, multi-pole current distribution. Compatibility Guide The 220V/240V AC variant of this 11-pin relay functions as a direct line-voltage sequence actor, bypassing the need for a low-voltage step-down control transformer. 1. Compatible Trigger Inputs Because this model runs on an AC 220V/240V coil, it interfaces smoothly with direct line-voltage equipment controllers: Line-Voltage Control Loops: Can be energized straight from mains power routed through industrial limit switches, float selectors, manual pushbuttons, or thermostats. PLC Relay Output Modules: Fits perfectly with mains-voltage relay or triac output cards on industrial Programmable Logic Controllers (PLCs). 2. Compatible Base Sockets (Mounting) To avoid manual wiring modifications or direct soldering to the heavy circular contacts, this plug-in component mates seamlessly with standard rail bases: PF113A / PF113A-E Sockets: The industry-standard matching 11-pin round-base screw-terminal socket blocks. They clip securely onto standard 35mm DIN rails, allowing field electricians to cleanly terminate raw panel wiring using a standard screwdriver. 3. Common Applications Triple-Phase Line Switching: Allows a standard line-voltage pilot signal to simultaneously switch or isolate all three legs of small auxiliary three-phase equipment (such as exhaust blowers, stirrers, or industrial heating banks). Intermediate Load Buffering: Operates as an easily swappable sacrificial interface to switch high-draw inductive equipment (like heavy contactor coils, industrial solenoid valves, and dampers) while shielding upstream logic control equipment. Complex Multi-Circuit Signal Branching: Instantly distributes a single system trigger (such as a line-level safety loop break) to perform three completely independent, isolated high-current operations at once.
