It is an isolated 12V 10A relay module with 16 channels, each relay can be switched on and off individually via -isolated digital input. The standard interface can be directly connected to microcontrollers and controlled by a of microcontrollers such as for , AVR, PIC, ARM, DSP, etc.Equipped with high current relay, maximum load: AC250V 10A, 15A 125VAC, DC30V 10A; -isolator current: 5mA.RELIABLE: Fault-tolerant design, even if the control line breaks, the relay will not move; With optical coupling insulation, 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 for relay output status. The working status indicator lights up to safe use.Colour:blueMaterial:pcbPackage Contents:1 x Relay ModuleOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
