TRU COMPONENTS Relay board 1 pc(s) Compatible with (development kits): Arduino

This is a LOW Level 5V 2-channel relay interface card and each channel requires a 15-20mA driver current. It can be used to control various devices and equipment with high current. It is equipped with a high current relay operating under AC250V 10A or DC30V 10A. The card has a standard interface that can be directly controlled by a microcontroller. The plate with four fixed screw holes all around, hole diameter 3.1 mm, convenient installation and fixed loose relay, relay selection of the quality single-pole double throw. A common end and start, a normally closed end isolation of optical coupling, anti-interference performance is well low level off, released at hohem. Suction status indicator on the right, enable status when the light is off VCC for system performance, JD_VCC power supply for the relays. The standard 5V relay, with jumper cap This text is machine translated.
