4 Channel Relay Controller Board
- 4 onboard SPDT Relays
- 7A Maximum Switching Current
- ULN2003 Relay Driver
- Very compact and easy to wire up
- Connects directly to TTL devices (Microcontrollers, Arduino, etc)0
Numato Lab's 4 Channel 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 four 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 popular Darlington array ULN2003. The relay coil is rated for 12VDC.
