2 Channel Relay Controller Board is a smart choice for controlling higher current loads from your microcontroller development board or a PC parallel port. This board has two on-board relays which can switch up to 10A. 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. Features & Technical Specifications: - • 2 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.) • Very compact and easy to wire up • 1.6mm FR4 PCB with black solder mask and white silkscreen • Two Relays with one three-pin screw terminal for easy connectivity Applications: - • Automated test fixtures • Industrial automation • Lighting Control
