WAGO Solid-State Relay, 50μA Minimum Switching Current, 33V Reverse Voltage Transistor - 857 Series - 857-724

Keen to switch your system on and off in a flash? Turn to this solid-state relay from WAGO. Thanks to an output voltage range between 0 and 24V DC, it's a versatile option for use in low-voltage setups. Rest assured, its turn-on time of 100μs and drop-out time of 600μs offer lightning-fast switching to minimise downtime. You can keep track of issues at a glance, thanks to the LED status indicator.

Features & Benefits

• Mounts onto a DIN rail for installation in a snap

• Slim dimensions of 81 (H) x 6 (W) x 94mm (D) save space in tight areas

• Performs reliably in demanding settings, thanks to a broad operating temperature range of -20°C to +70°C

• IP20 rating indicates it's touch-safe and protected against objects larger than 12mm in size

Applications

• Automotive facilities

• Transportation networks

• Processing plants

• Telecommunications

What's the difference between a solid-state relay and an electromechanical option?

SSRs have no moving parts that can wear down. This means that SSRs last longer than electromechanical relays.
