The IC660EPM100 is listed specifically as a “PowerTRAC, 115Vac/125Vdc Power” electronics assembly, while documentation for the assembly identifies compatibility with the IC660BPM100 PowerTRAC block.
One important correction for procurement: some secondary listings incorrectly describe IC660EPM100J as a 24 VDC power supply or even as a CPU. Those descriptions conflict with the Genius PowerTRAC documentation. The safer classification is PowerTRAC electronic assembly.
Application Scenarios & Pain Points
Electrical monitoring failures can be subtle. The PLC may continue running while operators see implausible current, power factor, frequency, or energy values. That makes the PowerTRAC electronics a maintenance concern even when the control logic itself is healthy.
- Plant electrical monitoring: The PowerTRAC assembly measures electrical parameters used for equipment and distribution monitoring.
- Motor and load monitoring: Useful for observing current, voltage, real/reactive power, and power factor associated with industrial loads.
- Energy measurement: The measurement architecture includes system power and total KWH functions, making it useful for older plant energy-monitoring installations.
- Genius distributed I/O systems: The assembly communicates through the Genius architecture as part of the PowerTRAC block rather than functioning as an independent PLC module.
Field note: If measurements suddenly become unreasonable, inspect the CT/PT wiring and terminal assembly before replacing the electronics. A loose current-transformer connection can produce symptoms that look exactly like a failed measurement board.

The Engineer’s Guide: Field Pitfalls to Avoid
⚠️ Do not treat IC660EPM100J as a conventional 24 VDC power supply.
Some secondary listings classify it incorrectly. The documented IC660EPM100 family belongs to Genius PowerTRAC and uses the IC660BPM100 block architecture.
How to avoid it: Verify the existing block designation and terminal assembly before ordering.
⚠️ Do not ignore the suffix.
The Genius EPM100 family has multiple letter revisions, including A, B, C, D, E, G, and H in historical listings.
How to avoid it: Match the complete IC660EPM100J designation and compare the board revision before installation.
⚠️ Do not condemn the electronics before checking measurement wiring.
Current and voltage measurements depend on the field wiring and sensing arrangement.
How to avoid it: Check CT/PT connections, terminal screws, fuses, grounding, and sensor wiring first. If the measurements are still incorrect, then isolate the electronics assembly as the suspect.
Frequently Asked Questions (FAQ)
What is GE IC660EPM100J?
The is a GE Genius I/O PowerTRAC electronic assembly used with the IC660BPM100 PowerTRAC block for electrical power monitoring.
Is a PLC CPU?
No. It should not be specified as a PLC CPU. Its function is associated with the PowerTRAC electrical measurement block, while the Genius network connects the block’s data to the control system.
What does the measure?
The PowerTRAC electronics support measurement of parameters including:
- Voltage
- Current
- Active power
- Reactive power
- Power factor
- System frequency
- Total KWH
- Harmonic power content
- Block temperature status
These functions are described for the IC660EPM100 PowerTRAC electronics family.
What PowerTRAC block works with ?
The associated block is IC660BPM100. The EPM100 electronics assembly is installed onto the PowerTRAC terminal/base assembly to form the complete block.
Can I replace with another IC660EPM100 revision?
Do not assume so. Historical EPM100 versions use different letter suffixes, and revision compatibility should be confirmed against the installed PowerTRAC block and system documentation.
What should I verify when buying a replacement?
For a maintenance purchase, I would record:
- complete part number.
- Existing block identification.
- Hardware/revision markings.
- Input voltage arrangement.
- CT/PT wiring configuration.
- Genius bus configuration.
- Existing power-monitoring parameters.
- Physical condition of the connector and terminal assembly.
- Functional measurement test.
- Test evidence for voltage/current/power measurement.
