How to Select an Interface Relay for PLC Outputs
A step-by-step guide to matching PLC output type, coil voltage and current, contact rating, and socket style when selecting an interface relay.
The Schneider Electric SR2USB01 is a 3 m USB programming cable for the Zelio Logic smart relay range. It connects a PC's USB port to the relay's programming port connector, allowing program upload and download, monitoring, and simulation through the Zelio Soft 2 software without a separate communication module or converter box.
The cable ships individually or in packs of 20 and weighs 0.1 kg. Its USB connector and 3 m length reach from a desktop or laptop PC to a DIN-rail-mounted Zelio Logic relay without an additional extension cable or adapter. It is the direct-connect alternative to a Modbus or Bluetooth communication module when the relay only needs occasional on-site programming rather than a permanent link.
