Songle Relay 12V 5pin JD1914

Description

Songle JD1914 5-Pin Automotive Power Relay (DC 12V Variant) The Songle JD1914 12V is a highly rugged, industry-standard Bosch-style automotive electromagnetic relay engineered for vehicular power distribution, safety interlocking, and accessory switching. Utilizing a standard 5-pin spade terminal layout, this SPDT (Single Pole Double Throw) relay relies on a 12V DC control coil to safely isolate, toggle, and route high-amperage electrical currents between two alternating circuits. Key Features Contact Configuration: SPDT (1 Form C: 1 Common, 1 Normally Open, and 1 Normally Closed contact line). Coil Voltage: 12V DC (Direct Current), matching standard automotive, marine, and power-sport battery electrical systems. High Switching Capacity: Built for heavy raw current spikes, typically rated to handle 30A to 40A at 14V DC (some heavy-duty clear-case variants support up to 80A loads). Visual Diagnostics: Available in standard black weather-resistant plastic shells, or transparent “ice-cube” casings equipped with an integrated LED indicator that lights up when the coil is energized. 5-Pin Pinout Layout (Standard Bosch Numbering): Pins 85 & 86: Solenoid Coil Input (Trigger Circuit) Pin 30: Common Feed (COM) Pin 87: Normally Open contact (NO — engages when energized) Pin 87a: Normally Closed contact (NC — engages when resting) Compatibility Guide The JD1914 series serves as the foundational switching block for nearly all aftermarket 12V automotive electronic additions. 1. Compatible Trigger Inputs Because this relay features a 12V DC coil, it integrates perfectly with standard vehicle accessory lines: 12V Dash Switches: Connects directly to low-current toggle switches, rocker switches, or push-buttons on the dashboard. Ignition / Accessory Lines: Can be spliced into the vehicle’s accessory wire loop to trigger auxiliary gear only when the engine key is turned. Electronic Control Modules: Directly driven by car security alarms, remote start kits, or central locking output pulses. 2. Compatible Mounting Sockets To avoid wiring mistakes or having individual spade connectors slip loose under heavy vehicle vibration, this relay plugs into standard automotive bases: 5-Wire Interlocking Relay Harness Sockets: The industry-standard matching socket block featuring heavy-gauge pre-wired leads (typically 12 AWG for load lines and 16 AWG for the control coil). These sockets feature interlocking slots on the sides, allowing multiple relays to be clipped together into a neat row inside an engine bay or under-dash bracket. 3. Common Applications High-Draw Off-Road Lighting: Manages the high current demand of auxiliary LED light bars, spot fog lights, and hunting search grids without melting factory dashboard switches. Performance Fuel Pumps & Cooling Fans: Supplies direct, uninhibited battery current directly to electric radiator cooling fans, high-pressure fuel pumps, and water pumps. Horn & Audio Systems: Safely triggers dual-tone air horns or provides clean high-amperage power distribution blocks to multi-channel aftermarket car audio amplifiers.
