Description

Numato Lab’s 16 Relay breakout module is a smart choice for controlling higher current loads from your microcontroller development board, PC parallel port, or your favorite Arduino. This board has sixteen on-board relays which can switch up to 7A. All relay terminals (C, NC, NO) are accessible through screw terminals which makes wiring up the board very easy. The relays are driven by the popular Darlington array ULN2803. The relay coil is rated for 12/24VDC as per the variant.

Features

  • Very compact and easy to wire up
  • 1.6mm FR4 PCB with Green solder mask and white silkscreen
  • Connects directly to TTL devices (Microcontrollers, Arduino, etc..)
  • Sixteen Relays with three-pin screw terminals for easy connectivity

Applications

  • Home Automation
  • Industrial Automation
  • Lighting Control
  • Garden Equipment Control
