Schneider Electric Solid State Relay, 24 to 280V AC Load Voltage, 4 to 32V DC Control Voltage - SSM1 Series - SSM1A120BD

Effectively switch off or amplify an electrical current with this solid state modular relay from Schneider Electric. It doesn't use voltage switching, letting it operate at a high frequency and higher input voltages without sacrificing efficiency. This makes it ideal for applications with resistive loads. The silicon-controlled rectifier output is hard-wearing and reliable, with a high mean time between failure that ensures minimal maintenance is needed. As the unit is up to 99.5% energy efficient, it minimises power consumption. This relay will operate in temperatures between -40°C to +80°C, making it suitable for demanding industrial environments.

Features & Benefits

• Built-in heatsink helps maintain a safe operating temperature
• DIN rail-mounted for straightforward installation
• Screw terminals give a secure connection

Applications

• HVAC systems
• Injection moulding machinery
• Textile industry
• Heating control devices

What are the advantages of solid state relays over electromechanical relays?

A solid state relay has no moving parts, so there's less wear and tear on components. This gives it a longer service life. Solid state relays also use less power than electromechanical alternatives and have a faster switching time.
