4-Channel Relay interface board and each one needs 15-20mA Driver Current. Both controlled by 12V and 5V input Voltage. Equipped with high-current relay, AC250V 10A ; DC30V 10A. Standard interface that can be controlled directly by microcontroller (Arduino, 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic active low). Indication LED’s for Relay output status.
Dual channel stereo, high output power (3 w + 3 w power @ 5V and 4 ohms load).. Double panel wiring solves crosstalk. Super mini design allows it to be easily placed in a variety of digital products. 3W Output at 10% THD with a 4ΩLoad and 5V Power Supply. Filterless, Low Quiescent Current and Low EMI and Low Noise. Short Circuit…
