RM2U USB Controlled وحدة ريلاي 2-قناة

RM2U USB Controlled Relay Module 2-Channel

RM2U is a 2-channel USB-controlled relay module. It can be used to control electrical devices remotely from a PC over a USB port such as lamps, motors, and locks. RM2U features a wide operating voltage range (9-ZKEEP0Z) and supports serial communication baud rate speeds starting from 2400 up to 115200 bps. RM2U module is well protected, filtered, and fully isolated.
