Technical Specifications

Engineering Advantages

The GE Fanuc IC693PWR325 stands out for its multi-rail power delivery, providing simultaneous 5VDC for logic and dual 24VDC outputs for relay and isolated input requirements. Despite its robust performance, the unit maintains a manageable weight of approximately 0.9 kg. A key safety feature is its overvoltage protection on the 5VDC rail, which safeguards sensitive CPU components from voltage spikes. Additionally, the integrated 1.45 Amp-hour battery provides essential memory backup during power loss, while its 12 lb-in torque rating ensures secure, vibration-resistant wiring connections in industrial cabinets.

Technical FAQs

Q1: What is the benefit of having "isolated" 24VDC output?
A1: The isolated 24VDC output is designed to power input modules while keeping the electrical noise of field devices separate from the sensitive internal logic of the PLC, improving system stability.

Q2: Can I use this module in a 12VDC system?
A2: No. The IC693PWR325 requires a minimum of 24 VDC to operate correctly. Applying voltage below the 24V threshold will likely prevent the power supply from initializing its output rails.

Q3: How often should the internal battery be replaced?
A3: While the battery is rated for a wide temperature range, typical replacement cycles are every 1-2 years depending on ambient temperature and the frequency of power cycles to ensure memory retention.
