PLC 4‑Channel Relay Expansion Board 4CH 30A Relay DC5V 12V 24V High‑Low Level Signal Trigger Control Module

EU LVD Voltage : Low voltage: Below 50Vac or 75Vdc Load Current : 30A High-concerned chemical : none Brand Name : Stlxy Voltage : 5V 12V 24V Origin : Mainland China Power Source : DC

Description: 1. The module adopts genuine high-quality 30A relay, the maximum load of the normally open interface: AC 250V/30A, DC 30V/30A. 2. With patch optocoupler isolation, strong driving ability, stable performance: trigger current 5mA. 3. The module operating voltage is 5V, 12V, 24V to choose from. 4. The module can be set high level or low level trigger by jumper. 5. Humanized interface design, all interfaces can be directly connected through the wiring terminals, very convenient. Product parameter Static current: 5MA Maximum current: 50MA/80MA/190MA Trigger current: 2-4mA Relay version: 5V/12V/24V Load current: 30A Load voltage: DC30V or AC250V It can control the maximum AC 250V, 10A AC load and the maximum DC30V 30A DC load Interface description 1.DC+ : module DC power supply positive electrode (contact voltage positive) 2.DC- : module DC power supply negative (trigger terminal voltage negative) 3.IN: signal trigger terminal (default trigger voltage is the same as power supply) 4. Select the high/low level trigger mode. When the jumper is connected to the end, the IN end is triggered at a low level, and when it is connected to the H end, it is triggered at a high level 5. Normally closed end (NC) : Normally closed end of the relay 6. Common end (COM) : The common end of the relay 7. Normal start (NO) : The relay is normally open

4‑channel independent relay module, each channel contact rating up to 30A. Coil supply optional: DC5V, DC12V, DC24V. Jumper selectable high‑level or low‑level trigger, compatible with PLC, MCU, Arduino, STM32 signal. Built‑in optocoupler isolation to suppress interference and protect main control unit. Independent LED indicator for each channel working status. Suitable for household intelligent modification, small PLC industrial control, automation DIY project. Notice: Do not exceed rated contact current; freewheeling absorbing circuit is recommended for inductive load. label:yes
