AOYI ST8‑5DD 8‑Channel 24VDC Solid State Relay
AOYI ST8‑5DD is an eight‑channel DC solid state relay module for switching 24V DC loads. Each channel is rated 5A, giving clean, silent, bounce‑free operation versus mechanical relays. It’s ideal for PLC expansion, machine panels, packaging lines, vending, and LED signage where fast and reliable DC switching matters.
Inputs are 24V DC and clearly marked “INPUT 24VDC.” A common positive bus is provided with individual channel triggers (‑1…‑8). Outputs are labeled T1…T8 as “OUT 24VDC 5A×8,” making wiring simple and service friendly.
