32 Channel Relay Controller Board
- 32 onboard SPDT Relays
- 7A Maximum Switching Current
- ULN2803 Relay Driver
- Very compact and easy to wire up
- Connects directly to TTL devices (Microcontrollers, Arduino, etc)
Numato Lab's 32-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 thirty-two onboard 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.
