Green PCB relay module with eight blue relays and screw terminals

V2 Technologies

V2 Technologies 2 in 1 accessory 8-Channel Relay Module 5V 12V 24V

SKU CH-216H-23D63

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

  • Optocoupler isolation protects control signals from electrical noise
  • Supports 5V, 12V or 24V DC supply for flexible integration
  • Each relay switches up to 30A at 250V AC or 30V DC
  • Configurable high or low level trigger per channel
  • On-board LED shows relay status for quick diagnostics

8-Channel Relay Module for Automation

This 8-channel relay module suits PLC automation, industrial control, IoT projects and experimental circuit work. It switches loads up to DC 30V or AC 250V at 30A per channel. The board operates from a DC supply of 5V, 12V or 24V, matching the relay coil voltage for stable operation. Optocoupler isolation on every channel provides strong anti-interference performance.

High and Low Level Trigger with Indicators

Each channel can be configured for high-level or low-level triggering, selectable per application needs. An on-board LED per channel shows relay on or off status at a glance. Quiescent current is 5mA, with maximum operating current of 190mA at 5V, 80mA at 12V and 50mA at 24V. Trigger thresholds vary by supply voltage, covering 0–2V low and 3.3–5V high at 5V, 0–5V low and 6–12V high at 12V, and 0–12V low and 12–24V high at 24V.

Industrial PCB with Barrier Terminals

The module uses an industrial-grade PCB and 9.5mm barrier terminals for secure wiring of power, signal and load connections. Mounting holes on the 8-channel board measure 249.5mm by 69.5mm, and overall dimensions are 252mm by 72mm by 22mm. Weight is 780g. Relay life exceeds 100,000 operations. Buyers needing more than eight switched circuits or a different coil voltage range will need additional modules.

Questions about this item

How often will the relay contacts need replacement under normal switching?

The relays are rated for more than 100,000 operations, so contact replacement depends on how frequently each channel switches in your application.

What limits continuous operation when all eight channels are energised at 5 V?

At 5 V supply the module draws up to 190 mA total, so the power supply’s current rating becomes the first limit during sustained use.

How much heat does the board produce when running all day at 12 V?

At 12 V the maximum operating current is 80 mA, giving roughly 1 W of dissipation spread across the 252 mm × 72 mm PCB, which remains modest in free air.
