MIN57C493

The MIN57C493 (commonly referenced as 57C493) is a high‑performance, industrial‑grade power supply module manufactured by Reliance Electric for the AutoMax PLC series, designed to deliver stable, regulated DC power to programmable logic controllers and associated I/O modules in demanding factory and process automation environments.

Engineered for reliability and efficiency, the unit accepts an AC input of 100–132 VAC at 50/60 Hz, with a nominal current draw of 6.5 A at 120 VAC, and converts it to a precise 24 VDC output at up to 376 W (approximately 15.7 A), ensuring clean, consistent power for control system electronics. It incorporates overvoltage, overcurrent, and short‑circuit protection circuits to safeguard connected hardware and minimize downtime in the event of electrical faults.

Constructed with a rugged, compact metal housing and rated IP20, the MIN57C493 is built to withstand industrial conditions, including dust, vibration, and moderate moisture. The operating temperature range spans 0 °C to 60 °C, with storage temperatures from −55 °C to +105 °C, allowing deployment across a wide spectrum of indoor and sheltered outdoor applications. Its dimensions are 298 mm (H) × 102 mm (W) × 160 mm (D), with a weight of 7.2 kg, making it suitable for standard rack‑mount installation in control panels.

Designed for seamless integration into Reliance Electric’s AutoMax PLC platform, the MIN57C493 supports hot‑swapping and mixed‑module configurations, enabling easy system expansion and maintenance. It features built‑in voltage regulation and filtering to suppress electrical noise, ensuring stable operation of sensitive control components and reducing the risk of data corruption or logic errors.

Typical applications include powering PLCs, I/O racks, motor drives, and automation peripherals in manufacturing lines, material handling systems, process control plants, and heavy machinery. As a key component in Reliance Electric’s industrial automation ecosystem, the MIN57C493 delivers OEM‑grade performance, durability, and protection, backed by the brand’s legacy of reliability in high‑demand industrial environments.
