Rajkumar published another project on Electronics Lab, an 8 channel relay board: 8 Channel Relay Board is a simple and convenient way to interface 8 relays for switching application in your project. Input voltage level support TTL as well as CMOS. Easy interface with Microcontrollers based projects and analog circuits.
Uwe tipped us to Texas Instruments’ low power 7-channel relay and inductive load sink driver ICs: TI offers two rather new low power 1,8V & 3.3V & 5V 7-channel relay and inductive load sink driver ICs: – ULN2003LV (Output/Switching Voltage max. 8V – e.g. for 5V relays) – ULN2003V12 (Output/Switching Voltage max. 16V – e.g. […]
