Green eight-channel relay board with screw terminals and optocoupler isolation

Tripowin

Tripowin 8-Channel Relay Module 24V Optocoupler Isolation 30A DC 30V AC 250V

SKU CH-VT7M-5CW6K

Eight-channel 24 V relay module with optocoupler isolation, selectable high or low trigger, and 30 A load capacity at DC 30 V or AC 250 V

  • Controls eight independent circuits from one board
  • Optocoupler isolation blocks electrical noise
  • Switches DC 30 V 30 A or AC 250 V 30 A loads
  • Selectable high or low level trigger logic
  • Industrial PCB with 9.5 mm barrier terminals

8-Channel Relay Module for Automation

This 8-channel relay module switches loads up to 30 A at DC 30 V or AC 250 V using optocoupler isolation for noise immunity. It operates from DC 5 V, 12 V or 24 V supplies and accepts both high-level and low-level trigger signals. Industrial-grade PCB construction with 9.5 mm barrier terminals provides secure wiring for PLC and industrial control panels.

Sustained Operation and Trigger Behaviour

Quiescent current is 5 mA and maximum operating current reaches 190 mA, so the module runs cool during continuous duty. Relay life exceeds 100 000 cycles, supporting long-term switching without degradation. Trigger thresholds are defined for each supply voltage: at 24 V, low-level trigger activates between 0‑12 V and releases at 12‑24 V, while high-level trigger activates at 12‑24 V and releases at 0‑8.5 V.

Selecting the Correct Coil Voltage

The single specification that decides fit is the coil supply voltage: the board must be powered at DC 5 V, 12 V or 24 V to match your control system. Buyers whose control logic runs at a different voltage cannot use this module without an additional supply. The package includes one 2‑channel relay module, so a second unit is required to obtain all eight channels.

Questions about this item

How much heat or power does the 24 V, 8-channel relay module draw when running all day?

The module draws a quiescent current of 5 mA and a maximum operating current of 190 mA at 24 V, so continuous power draw stays very low.

What supply voltage and trigger wiring must I already have to use this 24 V, 8-channel relay board?

You need a DC 24 V supply and a control signal that can swing between 0–12 V for low-level trigger or 12–24 V for high-level trigger.

Will the 9.5 mm barrier terminals on this 30 A relay module accept the same wire gauge as my older 10 A relay blocks?

The 9.5 mm barrier terminals are designed for the heavier conductors required by 30 A loads, so they are wider than typical 10 A terminal blocks.
