The GE Fanuc IC693PWR322 is a reliable standard power supply designed for use in the Series 90-30 PLC system, supporting a nominal input of either 24 or 48 VDC. It delivers an output power of 30 Watts and is engineered to be mounted in the leftmost slot of any IC693 baseplate. This power supply operates within a specified input voltage range of 21 to 56 VDC, ensuring consistent performance even with input voltages as low as 18 VDC, though initial startup requires at least 21 VDC. The unit features three distinct outputs: +5 VDC, +24 VDC relay output for compatible relay modules, and +24 VDC isolated power for input modules. Users should assess their specific application power requirements by referencing the individual module specifications available in the IC693 PLC Installation and Hardware Manual, ultimately utilizing a multiplication factor of 1.5 to calculate the necessary input power. Additionally, it is critical to account for startup surge currents and maintain a margin of 10-20% for input current calculations based on the lowest estimated operating voltage. This model includes an RS-485 serial communication port and a peak over-current limit of 4 Amps for 100 milliseconds, with an over-voltage limit of 6.4 to 7 VDC, ensuring robust operational integrity.
