Description:
The supply voltage of the FSC system is 24 Vdc, which can be powered from the plant’s 24 Vdc supply system with battery back-up. The FSC system requires an internal 5 Vdc supply to power the FSC modules. The 10300/1/1 DC/DC converter provides this internal 5 Vdc, with galvanic isolation between the two supply voltages.
Note: Keep the 10300/1/1 modules off-line for at least 30 seconds after being on-line. The 10300/1/1 modules have an NTC resistor as an inrush current limiter. Replacing or repowering the module within 30 seconds after removal or power-off may cause a supply voltage dip, which could trip the system, as the NTC resistor will not have cooled down sufficiently.

Notes:
- LED Behavior: For 10300/1/1 modules without a suffix code, the output LED may remain on in redundant configurations with a single I/O, even if the 10300/1/1 is switched off (LED is energized by a redundant 10300/1/1 unit).
- Module Modifications: 10300/1/1 modules with suffix code 04604 have minor board layout modifications to improve production yield and reliability. There are no functional changes.
- CE Approval: 10300/1/1 modules with suffix code 04602 or lower are not CE-approved.
