The Omron R88S-S104 is classified as a power supply unit that provides reliable and continuous output current rated at 4:00 amps. It is designed to function on single-phase AC power, accepting an input voltage of 100V while supporting both 50 and 60 Hz frequencies. The operating voltage range is flexible, covering AC 85V to 110V at 60 Hz and AC 85V to 121V.

For safety, the unit includes provisions for abnormal output conditions where it will activate open contacts, which helps prevent equipment damage. The abnormal contact capacity is rated at AC120V at 5 amps and DC24V at 2 amps. Thermal performance is a noteworthy attribute, as the R88S-S104 operates effectively within a temperature range of 0°C to 55°C, and its storage can be maintained between -10°C and 70°C. It can endure humidity levels between 35% and 90% RH for moisture management, provided there’s no condensation.

It is constructed for installation in an enclosure, adhering to an IP-30 ingress protection standard, ensuring adequate protection against dust and contact. The insulation resistance is notable, with a specification of ≥ 5 MΩ at 500V between external terminals and the casing to guarantee safety. Furthermore, the voltage withstand strength is established at AC 1500V for one-minute testing intervals to verify reliability. With regards to environmental resistance, it can tolerate vibration as specified by JIS C0911 at 16.7 Hz for ±3 mm over 30-minute durations in each axis (X, Y, Z), as well as handle shocks up to 10G along each axis, with three impacts, aligning with JIS standards. Overall, the R88S-S104 demonstrates robust performance suitable for demanding operational environments.
