Description
Product Introduction & Engineering Value
When expanding a VersaMax rack with multiple high-density analog modules or power-hungry communication interfaces, standard 1.5A power modules often fall short. The GE VersaMax IC200PWR102 solves this capacity wall by delivering a robust 3.3 Amps of 5 VDC backplane logic power (plus 1.0 Amp at 3.3 VDC), giving your rack double the power headroom of entry-level supplies.
Designed to snap cleanly onto any standard VersaMax CPU, Network Interface Unit (NIU), or Power Booster Carrier, the IC200PWR102 operates from a nominal 24 VDC field source (18–30 VDC range). It incorporates advanced over-voltage and over-current protection, ensuring that field power fluctuations or transient spikes never reach your critical PLC CPU memory registers or fieldbus logic circuits.

Field Application & The “Trench” Experience
During an emergency line addition at a high-speed bottling facility, engineers added two serial communication modules and four high-density 15-bit analog input cards (IC200ALG264) to an existing VersaMax remote Ethernet rack. Shortly after startup, the NIU began cyclically rebooting because the total 5V backplane current draw had exceeded 2.0 Amps, collapsing the standard power supply’s output rail. We swapped out the undersized supply for an IC200PWR102, restoring a rock-solid 5.0 VDC rail at 3.3A capacity and eliminating the network dropouts without replacing the rack structure.
Niche Application Scenarios:
- Fully Loaded Remote I/O Racks: Powering multi-card VersaMax Ethernet/Profibus NIU racks loaded with high-density analog modules.
- Compressor Control Panels: Supplying logic power in high-vibration engine cabinets where stable DC regulation is critical.
- Solar & Battery Backed Scenarios: Running directly off 24V industrial battery systems while isolating sensitive backplane logic from DC charging noise.

Transparency SOP: QA & Testing
To ensure every New Surplus or Remanufactured IC200PWR102 provides stable, ripple-free backplane power, our shop subjects every module to a strict 5-step validation protocol:
- Capacitor & Circuit Audit: Magnified inspection of the primary DC conversion stage, connector pins, and thermal pads to ensure zero degradation.
- Wide Input Voltage Swing Test: Variable DC bench test sweeping input voltage from 18 VDC to 30 VDC, verifying continuous voltage regulation.
- Full 3.3A Thermal Burn-In: Running the unit on a 3.3A / 5V dummy load bank for 4 hours while checking thermal dissipation with an infrared camera.
- Transient Line Dip Simulation: Inducing a 10 ms drop on the 24V supply line to confirm the supply maintains logic backplane hold-up without faulting.
- Short-Circuit Self-Protection Check: Inducing a temporary dead-short on the 5V rail to verify that automatic foldback current limiting engages instantly and recovers smoothly when the fault is cleared.
The Veteran’s Tech Trap Guide
- ⚠️ Not a Field Loop Power Supply! Remember that the powers backplane logic ONLY. It does NOT provide 24 VDC to power external field devices, 2-wire transmitters, or output solenoid coils connected to adjacent I/O cards.
- PRO TIP: Know the Difference Between PWR101 and PWR102! The IC200PWR101 is an AC supply (120/240 VAC input), whereas the requires a 24 VDC input. Connecting 120 VAC wall power to the terminals of an will instantly destroy the module!
- ⚠️ Calculate Your Combined Power Limit: While the module provides 3.3A on the 5V rail and 1.0A on the 3.3V rail, the total combined output power across both rails cannot exceed 20 Watts. Always double-check your total rack current calculations!
Dynamic FAQ
Q: Can I use the to replace a lower-capacity IC200PWB001A power module?
A: Yes. The shares the same physical mounting footprint and 24 VDC input wiring as the IC200PWB001A, but provides significantly higher current output (3.3A vs 1.5A @ 5VDC), making it an excellent direct upgrade.
Q: What does it mean if the front panel “PWR” LED stays off after landing 24 VDC?
A: A unlit LED indicates that either input voltage has fallen below 18 VDC, reverse polarity was applied to the DC terminals, or an over-current short on downstream backplane cards has tripped the supply’s protective foldback circuit.
Q: Does the require fan cooling inside the enclosure?
A: No. The unit uses convection cooling and is rated for standard 0°C to 60°C operational environments, provided standard panel clearance guidelines around the VersaMax rack are maintained.
Q: What warranty coverage comes with New Surplus and Refurbished units?
A: Every unit is fully load-tested and backed by a comprehensive 1-Year replacement warranty.
