Siemens Solid State Relay 12V DC

The Siemens Solid State Relay (SSR) 12V DC is an electronic switching device designed for controlling electrical loads without mechanical contacts. While exact details on a 12V DC control version are less common, Siemens SIRIUS 3RF2 series SSRs typically operate with control voltages ranging from 4 to 30V DC.

Here’s a general description based on Siemens 3RF2 series solid state relays (specifically for DC control):

• Control Voltage: Typically 4 to 30 V DC (which includes 12V DC within this range)

• Load Voltage Range: Can be from around 48V to 600V AC for switching the load

• Current Ratings: Models in this series support load currents varying from 10.5A up to 30A or higher depending on the exact model

• Switching Type: Usually zero-cross switching to reduce electrical noise and stress on connected devices

• Construction: Compact design, DIN rail or panel mounting options, with screw terminals for connections

• Output Device: Thyristor-based semiconductor switching, ensuring reliability and silent operation

• Operating Temperature Range: About -25°C to +60°C
