Power supply for the panel — 150 W, 24 VDC, 6.5 A
The Omron S8FSC15024 is a 150 W DIN rail switch-mode power supply from the S8FS-C series, delivering a nominal 24 VDC at 6.5 A from a universal AC input (100–120 VAC / 200–240 VAC). The 86% efficiency figure is typical for this power class and keeps heat dissipation manageable inside a sealed enclosure — expect around 24 W of waste heat at full load, which matters when you are stacking multiple supplies in a row on the DIN rail. Output is adjustable via a trim pot on the front face, giving you a small window above 24 V to compensate for cable drop to remote loads. Screw terminal block connections are standard; strip length and torque spec follow the label on the side of the unit.
MTBF and reliability context
The listed MTBF of 135,000 hours (calculated per Telcordia or similar standard) translates to a mean time between failures of roughly 15.4 years of continuous operation. For a DIN rail power supply running 24/7 in a control cabinet, that is a solid figure — it puts the expected service life well beyond the typical 10-year design horizon of most industrial machines. The 100 mV ripple and noise at the output is within spec for powering PLCs, sensors, and 24 VDC relays; if you are feeding sensitive analog transducers, a small output capacitor or a dedicated filter on the load side is cheap insurance.
Operating temperature range is -20°C to +60°C, which covers most indoor panel environments; above 50°C you will want to check the derating curve in the datasheet if you plan to pull the full 6.5 A continuously. Insulation voltage is rated at 3 kV between input and output, giving you basic isolation for SELV circuits downstream.
