ROPAM RM5-12V-4P 4-Channel 12V DC SPDT Relay Module with LED Indicators

The ROPAM RM5-12V-4P is a high-quality 4-channel relay module designed for reliable switching in industrial and automation applications. Each relay features SPDT (Single Pole Double Throw) contacts, capable of switching up to 5A resistive load at 250V AC or 30V DC. The module operates on a 12V DC coil voltage and includes four LED indicators for easy status monitoring. With screw terminals and DIN rail or screw mount options, it offers flexible installation. The robust ABS housing ensures durability, while the AgSnO2 contacts provide excellent performance and long electrical life.

Advantages

Compact 4-channel design saves space in control panels. LED indicators provide immediate visual feedback on relay status. High dielectric strength (4000V AC coil to contact) ensures safety and reliability. Suitable for a wide operating temperature range (-25°C to +55°C).
