The HGM1008 is a solid-state relay module manufactured by Coto Technology. The module provides a low-cost, efficient means of controlling the switching of electrical loads such as motors, lamps, and pumps. The module requires only a single digital signal, such as a logic level signal, low voltage DC signal, or PWM signal to control the switching of AC or DC loads. It also features pluggable relay terminals, which make maintenance easy and can be used in applications where space is limited. The module is also UL recognized and has a wide operating temperature range of -40°C to 70°C.
