YOKOGAWA PW482-11 S2 Power Supply Module

Configured for direct AC to DC energy conversion in ProSafe-RS Safety Control Stations, the YOKOGAWA PW482-11 S2 (PW482 Power Supply Module) provides direct physical/electrical execution. It transforms 100-240 V AC mains voltage into a regulated 24 V DC system power rail to maintain continuous operation across safety-instrumented backplanes.

Channel-to-Channel Isolation & CJC Integrity

The unit incorporates channel-to-channel isolation topology alongside galvanic separation between the high-voltage AC utility grid and internal system backplane logic. This architectural boundary prevents common-mode ground loops and severe transient surges from propagating into sensitive digital logic buses. Additionally, internal thermal management limits localized heat generation near field wiring subracks, thereby maintaining cold junction compensation (CJC) stability and baseline signal integrity across adjacent analog input cards mounted within the same station frame.

Frequently Asked Questions

Q: Does the module support active redundant configurations without output power interruption?

A: Yes. Two units install in parallel across the subrack power bus. Internal diode ORing logic isolates a failed module instantly, allowing the surviving unit to carry the total 4 A current load without dropouts on the 24 V DC rail.

Q: Can maintenance personnel replace this power module while the Safety Control Station remains online?

A: Personnel can safely hot-swap the module in redundant power configurations. Removing a faulty secondary unit does not disturb system backplane execution, provided one power supply remains operational.

Field Installation Guidelines

Mount the unit vertically into the designated ProSafe-RS SCS subrack slot to ensure natural thermal convection through the chassis vents. Maintain a minimum clearance of 50 mm above and below the subrack frame for unhindered airflow. Secure the primary AC line inputs using recommended terminal lugs, and torque all retention screws to specified chassis standards to prevent vibration looseness. Ground the subrack frame directly to the master plant protective earth (PE) bus through a dedicated low-impedance conductor before applying mains power.
