16 Channel 05V Relay Module

SKU: Mod#36




  • 5V 16 channel relay contact capacity is 10A 250V per channel, with optocoupler protection.
  • Onboard power supply module does not need an external power supply.
  • I / O port driver is active in low level.
  • Used as a microcontroller development board, can be used as appliance control, also can be used as PLC output expansion.
  • Description:
  • The control signal voltage range: The trigger signal is low level 0-2V, high level voltage can not exceed 5V.
  • Built-in optocoupler isolation, high anti-interference ability, stable performance, trigger current is only need 3mA.
  • 1-16 channel optionally fully open / closed, or any channel.
  • Output Type: AC 220V 10A direct connection or DC 30V 10A load.
  • Each relay common terminal COM is independent, for access to different signals, each relay with both normally closed and normally open port.
  • Each comes with relay action indicator, pull lit, disconnect extinguished.
  • Humanized interface design, all interfaces can connect directly through the terminal leads, very convenient.
  • It has four mounting bolts holes for easy installation.
  • PCB board size: 180 x 90 x 20mm (L * W * H)


Supply voltage: 5V DC

Supply current: More than 200mA

Each relay can load: 250V 10A (AC) or 30V 10A (DC)


Power supply need to meet the range, DC 5V.

Load power need to have certain margin for relay, it should avoid high-power (about 2000W). If working long hours, have a certain impact on the life of the product.
