These indicators help monitor the power supply’s performance and ensure smooth system operation. Moreover, the module supports RS-485 communication, enabling easy integration with a programming workstation, GE Fanuc handheld programmers, and other compatible devices.

Applications

This power supply module is a critical component for powering Series 90-30 PLC systems. It supplies power to the backplane and Series 90-30 I/O modules, ensuring that the system remains operational in demanding industrial environments. The IC693PWR322 supports three distinct output voltages: 5VDC, used for backplane power; 24VDC Isolated, used for 24V input modules; and 24VDC Relay, providing power to relay modules.

Additionally, this power supply module incorporates important safety features such as overvoltage protection and overcurrent protection, helping safeguard the system against electrical issues. Its holdup time of 14 ms and ride-through time of 10 ms ensure that the system continues to function smoothly during brief power interruptions. The module also features a RAM battery to maintain data retention, which can be replaced using the IC693ACC301 part.
