PENGLIN 16 Channel 12V Relay Module With Optocoupler Low Level Trigger Expansion Board For Raspberry Pi Arduino

It is an isolated 12V 10A relay module with 16 channels, each relay can be switched on and off individually via opto-isolated digital input. The standard interface can be directly connected to microcontrollers and controlled by a variety of microcontrollers such as Arduino, AVR, PIC, ARM, DSP, etc. Equipped with high current relay, maximum load: AC250V 10A, 15A 125VAC, DC30V 10A; opto-isolator tripping current: 5mA. RELIABLE: Fault-tolerant design, even if the control line breaks, the relay will not move; With optical coupling insulation, tripping more reliable, more stable. EASY INSTALLATION: Equipped with screwed terminal plate and fixed screw holes (diameter: 3.1mm) on both sides for easy installation. With indicator LEDs for relay output status. The working status indicator lights up to ensure safe use.
