RM8U USB Controlled Relay Module 8-Channel

RM8U USB Controlled Relay Module 8-Channel

RM8U is an 8-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. RM8U features a wide operating voltage range (9-40V) and supports serial communication baud rate speeds starting from 2400 up to 115200 bps. RM8U module is well protected, filtered, and fully isolated.
