Relay Module 2 Channel 12V (high/low) level trigger

75.00 EGP

This 2-Channel 12V Relay Module allows you to control high-voltage/high-current devices (up to 250V AC / 30V DC @ 10A per channel) using a 12V control signal, making it ideal for automotive, industrial, and home automation applications. Each relay features optocoupler isolation for protection against voltage spikes and supports both HIGH and LOW-level triggering (configurable via jumper).

Description

🔑 Key Features

✅ 2 Independent SPDT Relays – Control two circuits separately.
✅ 12V DC Control Voltage – Works with car electronics, PLCs, and 12V microcontrollers.
✅ Optocoupler Isolation – Prevents damage to control circuits.
✅ High/Low Level Trigger Selectable – Jumper-configurable for flexibility.
✅ LED Status Indicators – Visual feedback for relay activation.
✅ Screw Terminal Connectors – Secure wiring for high-power loads.
✅ Wide Compatibility – Supports AC (250V/10A) and DC (30V/10A) loads.

🔌 Wiring & Usage

1. Control Connections (12V Logic)

  • VCC: Connect to 12V power supply (for relay coil).

  • GND: Common ground (shared with control signal).

  • IN1, IN2: Signal pins (activate with 12V HIGH or LOW, depending on jumper setting).

2. Load Connections (Screw Terminals)

  • NO (Normally Open): Circuit closes when relay is ON.

  • COM (Common): Central contact.

  • NC (Normally Closed): Circuit opens when relay is ON.

⚠ Warning:

  • Do not exceed 250V AC / 10A per channel.

  • Keep high-voltage wiring separate from control circuits.


🛠 Applications

  • Automotive systems (12V car electronics, lights, fans).

  • Industrial machine control (PLC interfacing).

  • Home automation (appliance control via 12V triggers).

  • DIY power distribution panels.

  • Safety cutoffs & emergency switches.


📦 Package Includes

  • 1× 2-Channel 12V Relay Module.

  • (Optional) Jumper caps & mounting screws.


⚡ Why Choose This Relay Module?

✔ 12V-Compatible – Perfect for automotive & industrial use.
✔ Dual Trigger Modes – Works with active HIGH or LOW signals.
