Robotbanao Optocoupler 8-Channel Relay Control Panel Plc 5v Module for Arduino Electronic Components Electronic Hobby Kit

This item is a 5v 8 channel relay interface board,it can be controlled directly by a wide range of microcontrollers such as for , avr, pic, arm and so on. 8 channel relay interface board. Each one needs 15 20ma driver current. Equiped with high current relay: dc30v 10a ac250v 10a. Each relay has normally open and normally closed contact. The 8 channels are optically isolated, safe, reliable, anti interference. Can be selected by jumper relay and ttl or ground. With power indicator,8 way road has a status indicator. With a relay coil to absorb the diode protection. The circuit board size 140mm x 55mm mounting hole size 133mm x 40mm. This 8-channel relay module can be used to control various appliances, and other equipment with large current. It can be controlled by a number of microcontrollers such as Arduino, AVR, PIC, ARM. It is ideally suited to controlling larger voltages in your project through Wi-Fi. It can be used to control 220V AC load. It has a normally open contact and one normally close contact.
