The YOM4/24D1006 with Solid State Relays Module RoHS manufactured by Silicon Billion is a 24-channel relay module with a 100V AC/DC input voltage. It is designed with Opto-Isolated inputs, allowing for routine status monitoring and protection against electrical noise. It also has a coil rating of up to 7A at 100V AC/DC and a built-in over-temperature and over-current protection feature to ensure safety and reliability. Furthermore, its UL file number (E351426) ensures a higher level of compliance with fire safety standards. The RoHS compliant module also has an improved output contact force and temperature capability, reducing contact problems, corrosion and arcing.
