YOKOGAWA PS-502-01 is a power module designed by Yokogawa Electric for industrial automation and safety control systems. It is commonly used in systems such as CENTUM DCS or ProSafe SLS to provide stable and reliable DC power supply for controllers, I/O modules, etc.
The input voltage is 24V DC ± 10%, which can temporarily withstand+20% fluctuations.
Provide two outputs: regulated output 20V DC ± 1%, non regulated output 24V DC.
The maximum total output current is 1A, and the total of the two loads does not exceed this value.
Using serial voltage stabilization method, the full load efficiency is about 71%.
Equipped with electronic current limiting and short-circuit turn back protection (approximately 0.35A in case of short circuit).
Built in 2A fast fuse, red LED for input status indication.
Supporting parallel redundant configuration, seamless fault switching can be achieved when using dual power supplies.
The working temperature range is -20 ℃ to+70 ℃, and the storage temperature is -25 ℃ to+85 ℃.
The impact resistance is 10g (16ms), and the vibration resistance is 10-55Hz (± 0.35mm).
Adopting DIN 41612 48 pin interface, single Euro card specification (160 × 100 × 30 mm).
Protection level IP20, suitable for installation inside cabinets.
The front panel is equipped with LED status indicator lights, making the operating status clear at a glance.
Compatible with ProSafe SLS security system and CENTUM CS/VP series DCS.
Compliant with EN 50081-2 and EN 50082-2 electromagnetic compatibility standards.
Suitable for harsh industrial environments such as petroleum, chemical, power, water treatment, etc. that operate continuously.
In summary, the YOKOGAWA PS-502-01 power module has 24V input, dual output, redundant support, and wide temperature operation capability, providing stable and reliable power supply guarantee for the Yokogawa control system.
