Verify the source
Measure dc voltage and polarity at the isolated feeder and confirm that the source remains within the applicable input range under load.
Series Six 24 Vdc Power Conversion
GE Fanuc IC600PM541 / IC600PM542 Series Six 24 Vdc Power Supplies
Twenty-four-volt dc Series Six supplies for CPU/DPU racks and high-capacity I/O racks.
IC600PM541CPU/DPU dc power supply
IC600PM542High-capacity I/O rack dc power supply
Product Description
IC600PM541 and IC600PM542 allow Series Six equipment to operate from a nominal 24 Vdc source. IC600PM541 is the CPU/DPU rack supply; IC600PM542 is the high-capacity I/O rack supply. Their common input family supports battery or inverter sources, but their rack roles are different.
IC600PM541 mounts at the extreme right of the processor rack and provides regulated +5 V, +12 V and -12 V rails to the backplane. IC600PM542 supplies high-current I/O configurations and remote I/O applications, includes reverse-polarity protection and generates the PSOK signal used for initialization and error indication.
Before replacement, verify dc-source range, polarity, conductor size, protective device, rack load and the exact processor or I/O rack. The high-capacity I/O supply allows 275 +5 V load units, but the combined output load must still remain within the documented total power limit.

Power Capacity and Protection
IC600PM541 converts the 20-32 Vdc source for a processor rack and feeds the three regulated backplane rails required by CPU hardware.
IC600PM542 is sized for a high-capacity I/O rack and provides 6.1 A at +5 V, 1.5 A at +12 V and 1.0 A at -12 V within the documented total-load limit.
The I/O supply produces PSOK for rack initialization and error handling, and its input is protected against accidental reverse polarity.
Load-unit totals must be calculated across every installed board; spare slot count does not prove that electrical capacity remains available.
Installation and DC Source Checks
Confirm the rack
Use IC600PM541 for the CPU/DPU position and IC600PM542 for the high-capacity I/O rack; do not swap roles.
Calculate capacity
Add +5 V, +12 V and -12 V load units for all installed modules and observe the total-output limit.
Energize safely
Restore dc power with field outputs controlled, confirm logic-power and PSOK behavior, then validate processor or I/O operation.
Product FAQ
Can IC600PM541 replace IC600PM542?
No. IC600PM541 is the CPU/DPU supply; IC600PM542 is the high-capacity I/O rack supply.
What dc source range is documented for IC600PM541?
The CPU/DPU dc supply is specified for a 20-32 Vdc source such as a compatible battery or inverter system.
What outputs does IC600PM542 provide?
It provides +5 Vdc at 6.1 A, +12 Vdc at 1.5 A and -12 Vdc at 1.0 A, subject to the rack load-unit and total-power limits.
What is the purpose of PSOK on IC600PM542?
The power-fail/OK signal is used by the Series Six rack for initialization and error indication.
Which checks are required after installing IC600PM541 or IC600PM542?
Confirm dc polarity and input range, stable backplane rails, power/PSOK indication and correct CPU or I/O behavior under the documented load.
