4 Channel Relay

4‑Channel Solid‑State Relay Module – High‑Speed, High‑Isolation Control

This compact 4‑channel relay module delivers fast, electrically isolated switching for a wide range of AC and DC loads. Each channel contains a high‑efficiency MOSFET or TRIAC driver that allows the relay to switch either 0‑5 V control logic or 5‑10 V analog signals, making it ideal for use with microcontrollers, PLCs, and industrial automation systems.

The module features low‑crosstalk isolation, rapid activation times (≤5 ms), and robust surge suppression. Its mounting pattern and standardized headers enable straightforward integration into PCB prototyping boards or single‑panel control cabinets, reducing assembly time while maintaining reliable performance in harsh environments.

• Key Spec 1: 4 independent channels, each rated up to 10 A at 250 VAC or 15 A at 30 VDC
• Key Spec 2: Input control voltage 0–5 V, with optional 5–10 V logic level support
• Key Spec 3: Opto‑isolated driver per channel, ≥200 V isolation, and 250 kΩ leakage current
• Common Use Case: Precise, isolated control of motor drives, HVAC coils, LED lighting arrays, and power supplies in industrial or hobbyist projects
