Description

Key Technical Specifications

The IC693PTM101 is the longer-cable version of GE Fanuc’s Series 90-30 Power Transducer Module. The package contains the processing module, its matched interface board, and a 39-inch (1 m) interface cable. GE’s manual explicitly states that the processing module and interface board are a matched set and should not be separated as individual replacement components.

The PTM accepts voltage and current signals from user-supplied potential transformers (PTs) and current transformers (CTs). It calculates electrical parameters including RMS voltage/current, kW, kVAR, kVA, power factor, frequency, and accumulated energy.

Product Introduction

The GE Fanuc IC693PTM101 is a Series 90-30 Power Transducer Module used for electrical power monitoring and generator-to-grid synchronization applications. It processes voltage and current signals from external PTs and CTs, then transfers calculated measurements into the PLC for reporting, control, load-shedding, and fault-monitoring functions.

The IC693PTM101 supports 10–150 VAC RMS voltage measurement, 0–7.5 A RMS current measurement, and 35–70 Hz operation. Its distinguishing feature versus the IC693PTM100 is the supplied 1 m interface cable, rather than the 0.5 m cable supplied with the PTM100.

• No current measurement: Check CT wiring and polarity.
• Incorrect power factor: Check phase-to-CT correspondence and CT polarity.
• Voltage readings correct but kW is wrong: Suspect phase/CT association or ratio configuration.
• PLC receives no PTM data: Check rack seating, PTM configuration, and PLC data mapping.
• Different readings from the old unit: Compare CT/PT ratios and phase assignments before replacing additional hardware.

Frequently Asked Questions (FAQ)

Q1: What is the used for?

The is an intelligent power measurement and monitoring module for the GE Fanuc Series 90-30 PLC. It measures electrical voltage and current through external PTs and CTs and calculates parameters such as real power, reactive power, apparent power, energy, frequency, and power factor.

It can be used for power monitoring, reporting, load shedding, fault monitoring, and generator/grid synchronization applications.

Q2: What is the difference between IC693PTM100 and ?

The primary difference is the supplied interface cable length.

• IC693PTM100: 0.5 m cable
• 1 m cable

GE’s documentation states that the processing module and interface board are matched components, while the two cable lengths are separately cataloged as IC693CBL340 and IC693CBL341.

Q3: What voltage and current can the measure?

The documented measurement range is approximately 10–150 VAC RMS for voltage and 0–7.5 A RMS for current, with a nominal current range of 5 A RMS. The operating frequency range is 35–70 Hz.

The PTM is intended to work with external PTs and CTs. Do not connect primary generator or utility voltage directly to the module.

Q4: Can the be hot-swapped?

No. Treat the processing module as a power-off replacement, and more importantly, treat the interface-board wiring as a potentially hazardous electrical circuit.

The Series 90-30 rack can be powered down for the module replacement, but the PT/CT circuits require their own electrical isolation procedure. GE explicitly warns about hazardous voltage at the PTM interface board.

Q5: Is obsolete?

Yes. The is a discontinued legacy Series 90-30 product. Current industrial automation suppliers list it as obsolete while continuing to offer new-surplus and refurbished inventory.

For a production spare, request the exact processing-module revision, interface-board revision, cable length, condition, test report, and warranty. Do not purchase based only on the catalog number.

Q6: Does include the interface board and cable?

Yes. The catalog configuration includes the processing module, matched interface board, and 1 m interface cable. The IC693PTM100 uses the same general PTM architecture but includes a 0.5 m cable.

This matters when comparing surplus listings. A listing for only the processing module is not equivalent to a complete package.

Q7: Can the be used for protective relay or billing applications?

No. GE’s catalog specifically states that the PTM is intended for power measurement and monitoring and is not intended to provide a protective relay function or to be used for energy billing purposes.

For protection or revenue metering, use equipment specifically certified and designed for those functions.
