Description
- Brand: GE Fanuc
- Full Model Number: IC660TSA100
- System/Series Family: GE Genius I/O
- One-Sentence Core Function: Terminal assembly for the IC660BBA100 115 VAC analog Genius I/O block
- Top 3 Hardcore Specs: 4 analog inputs + 2 analog outputs; 115 VAC nominal block architecture; 1500 V block-to-block isolation
- Stock Status: New surplus / fully tested refurbished
GE’s Genius I/O documentation identifies IC660TSA100 as the terminal assembly for the IC660BBA100, a 115 VAC, 4-input/2-output analog I/O block. The complete block is formed from a terminal assembly and a separate electronics assembly, allowing the two sections to be ordered independently.
Module 3: Commercial-Technical Deep Dive
A damaged terminal assembly can force an otherwise healthy Genius analog block out of service simply because field wiring, terminal hardware, and electronics interface through the same mechanical assembly. The GE IC660TSA100 provides the field termination for the IC660BBA100 analog block, supporting a 4-input / 2-output configuration. GE’s manual identifies the associated BBA100 architecture as a 115 VAC analog I/O block, with the TSA100 serving as the terminal section and the EBA100 as the corresponding electronics assembly.
For replacement planning, the electrical isolation and physical dimensions are more relevant than firmware. The documented complete BBA100 block is approximately 8.83 in × 3.50 in × 3.94 in, with a reference block weight of about 4 lb and 1500 V block-to-block isolation; these figures describe the complete analog block rather than the bare TSA100 terminal assembly. The associated 115 VAC architecture is specified for approximately 98–132 VAC, 47–63 Hz, with about 10 VA maximum block power and a 1-cycle power-supply dropout tolerance.

Module 4: Compatibility & Installation Traps
Migration/Compatibility
- Replacement type: GE Genius analog I/O terminal assembly
- Model: IC660TSA100
- Associated complete block: IC660BBA100
- Associated electronics assembly: IC660EBA100
- I/O architecture: 4 analog inputs + 2 analog outputs
- Nominal block power: 115 VAC
- Firmware flash: Not applicable to the passive terminal assembly
- Logic rewrite: Not applicable
- Drop-in status: Generally suitable when replacing the terminal assembly on the same IC660BBA100 architecture, subject to connector, revision, and field-wiring compatibility
- Assembly relationship: GE documentation explicitly lists TSA100 as the terminal assembly for BBA100 and EBA100 as the associated electronics assembly.
⚠️ Field Traps (Watch Out)
1. IC660TSA100 is not a complete analog I/O block.
The TSA100 is the terminal assembly only. The active electronics are in the corresponding electronics assembly, and GE’s catalog structure explicitly permits terminal and electronics assemblies to be ordered separately.
2. Do not confuse TSA100 with TSA020.
The TSA100 belongs to the 115 VAC 4-input/2-output analog block, while TSA020 is associated with the 24/48 VDC analog block family. The similar part numbers do not indicate electrical interchangeability.
3. Verify the complete block revision before replacement.
The IC660TSA100 has a long revision history, and current inventory listings include multiple suffix revisions. Match the exact physical terminal assembly and the corresponding electronics revision before installation rather than relying on the base number alone.
4. Field wiring remains part of the compatibility check.
A terminal assembly with the correct catalog number can still create commissioning problems if the original wiring arrangement, signal polarity, commons, or analog-channel assignments are not reproduced exactly. Photograph and label all conductors before removal.
5. Verify the AC architecture.
The associated BBA100 is a 115 VAC block. Do not substitute the into a low-voltage DC analog block merely because the mechanical housing appears similar.
Module 5: Quality Assurance SOP
Each GE unit should pass a documented pre-shipment inspection sequence:
- OEM anti-counterfeit visual inspection: Verify GE Fanuc identification, marking, terminal geometry, connector arrangement, housing construction, and manufacturing labels.
- Exact part-number verification: Match the complete identifier against the purchase order and installed Genius I/O BOM.
- Assembly pairing verification: Confirm that the intended mating electronics assembly is IC660EBA100 and that the complete system corresponds to the IC660BBA100 architecture.
- Mechanical inspection: Check terminal blocks, screws, contact interfaces, mounting points, insulation barriers, housing, and connector surfaces for cracks, corrosion, contamination, or impact damage.
- Terminal integrity inspection: Verify every terminal position is mechanically secure and free of loose hardware, stripped threads, damaged clamps, or excessive oxidation.
- Power-path inspection: Inspect accessible power terminals and associated wiring interfaces for heat discoloration or electrical damage.
- Power-on self-test (POST): Not applicable to the terminal assembly itself. Testing should be performed with a compatible EBA100 electronics assembly installed as a complete BBA100 block.
- Analog I/O verification: In the complete test assembly, apply calibrated analog signals to the four input channels and verify correct field-terminal continuity and signal transfer.
- Analog-output verification: Exercise the two analog output circuits and verify correct terminal routing and measured output behavior.
- Isolation verification: Where the approved test fixture supports it, verify the expected isolation properties of the complete block; the published 1500 V isolation specification applies to the BBA100 block architecture.
- Genius communication handshake verification: Perform system-level communication testing through the associated electronics assembly and Genius Bus interface.
- Final QC: Photograph the identification and terminal layout, record inspection results, protect all terminal hardware from impact, and package the assembly securely.
Module 6: CRO-Driven Buyer FAQ
1. What is GE ?
The is a GE Fanuc Genius I/O terminal assembly for the 115 VAC analog block. It provides the field-wiring termination section, while the corresponding electronics assembly is IC660EBA100.
2. What analog configuration does the support?
The associated is a 4-input / 2-output analog I/O block. Those channel-count specifications describe the complete assembly, not the as an independent electronic module.
3. Is compatible with IC660TSA020?
No automatic substitution should be assumed. is associated with the 115 VAC analog block family, while TSA020 belongs to the 24/48 VDC analog family. Confirm the complete block catalog number and power architecture before ordering.
4. Can be hot-swapped?
Do not assume hot-swap capability. The terminal assembly is part of a Genius analog block carrying field wiring and AC-related circuitry. Replacement should be performed with the relevant equipment de-energized and the field wiring secured according to the applicable maintenance procedure.
5. What warranty and technical support are provided?
Warranty duration should be stated on the quotation for the exact inventory condition supplied. Technical support should cover part-number verification, terminal/electronics assembly matching, wiring-layout checks, inspection records, and complete-block functional testing. Field rewiring and energized maintenance remain the responsibility of qualified personnel.
