Machine-mounting power supplies speed installation and ease visibility
3 August 2026 
Omron has launched an IP67-protected power supply designed to be mounted on machinery, outside of the control panel, resulting in rapid installation and easy visibility. The S8NR supply spans ratings from 90–600W, 24V DC. Omron has also introduced an IP67-rated DC blocking box (S8R-BB), which allows control circuits to be wired outside the panel too.
The 360W and 600W versions have up to six individually protected outputs, cutting the number of separate parts to select and wire. A digital display on these models shows live voltage, current and fault status for each channel. For fast fault-finding, every output has a LED that normally appears green – or red if it trips. A maintenance-forecast function tracks the condition of the supply’s capacitors and reports (in years, and as a percentage) when it will need replacing, allowing maintenance to be planned before any failures. Data can be read, and the supply configured, remotely via IO-Link.
Omron’s Smartclick quick-connect system cuts the time to make a connection to about four seconds, compared to around 12s for screw connectors. A keyhole mounting bracket allows one person to hang and align the supplies. DIN-rail mounting is available as an alternative to screw fixing. Trip currents can be set in 0.1A steps, and start-up sequencing delayed in 0.1s steps per output. Inrush currents will not trip the supply when several loads switch on together.
The DC blocking box extends this approach to control circuits, using the same Smartclick connection system so that power and safety wiring can both be done at the machine. Omron says that using the S8NR-S and S8R-BB together can cut the number of components an engineer needs to select from ten to two.
