Description
Product Introduction & Engineering Value
The ABB LC1000-SSP7 is a legacy ABB industrial component encountered in the automation spare-parts market. Current secondary sources generally associate it with the ABB LC1000 series and describe it as a compact control/monitoring device.
One source reports a 24 VDC supply, four digital inputs, four digital outputs, analog I/O, and a four-digit LED display. Another source reports PROFIBUS DP functionality and a different physical/electrical specification set.
Because these sources disagree materially, specifications such as input/output ranges, communication protocols, dimensions, IP rating, and current ratings should not be treated as universally verified for every LC1000-SSP7.
That distinction is important when sourcing legacy industrial electronics.
Technical Specifications
| Parameter | Available Information |
|---|---|
| Manufacturer | ABB |
| Model | LC1000-SSP7 |
| Series | LC1000 |
| Product Category | Control / monitoring module |
| Supply | 24 VDC reported by some sources |
| Digital Inputs | 4 reported |
| Digital Outputs | 4 reported |
| Analog Inputs | 0–10 VDC / 0–20 mA reported |
| Analog Outputs | 0–10 VDC / 0–20 mA reported |
| Display | 4-digit, 7-segment LED reported |
| Communication | PROFIBUS DP reported by secondary sources |
| Operating Temperature | Source-dependent; verify exact unit |
| Mounting | Verify from original hardware |
| Dimensions | Conflicting secondary specifications |
| Weight | Approximately 0.25 kg reported by one source |
The 24 VDC supply, 4 DI/4 DO, analog I/O, and 7-segment display data are published by an ABB LC1000-SSP7 listing.
However, another listing gives 100–240 VAC input, 0–230 VAC output, 7 A maximum current, IP56, and a completely different physical format. A third source describes it as a 1000 A electrical-control component.
Engineering conclusion: those contradictory specifications should not be merged into one product specification sheet. The unit’s nameplate, PCB markings, and original ABB documentation should be used to establish the exact variant.

Field Application & the “Trench” Experience
For legacy ABB equipment, the biggest procurement problem is often not finding a part number. It is finding the correct hardware revision behind that part number.
If an LC1000-SSP7 is being replaced, first record:
- Complete model number.
- ABB article/ordering number, if present.
- Hardware revision.
- Serial number.
- Connector arrangement.
- Installed equipment model.
- Existing communication interface.
- Photographs of the complete unit.
This information is especially important for LC1000-SSP7 because public secondary listings currently provide contradictory descriptions.
Typical Procurement Applications
The component is encountered in legacy ABB industrial automation and control inventories, with secondary listings associating it with industrial control, electrical systems, and automation applications.
Transparency SOP: QA & Testing
For New Surplus or Rshed stock:
Identification
Verify:
- ABB logo/marking
- Complete article number
- Hardware revision
- Serial number
- Connector layout
- PCB revision
Physical Inspection
Check:
- PCB contamination
- Oxidation
- Connector damage
- Cracked solder joints
- Burn marks
- Damaged terminals
- Capacitor condition
- Evidence of previous repair
Functional Test
Testing should be based on the confirmed variant.
If the installed unit is confirmed to be the control/I/O version, test:
- 24 VDC power-up
- Display operation
- Digital inputs
- Digital outputs
- Analog channels
- Communication interface
- Diagnostic functions
If the physical unit corresponds to a different LC1000-SSP7 configuration, use the applicable test procedure instead.
The Veteran’s Tech Trap Guide
⚠️ Trap #1 — Trusting the first online specification sheet.
LC1000-SSP7 listings currently contain materially conflicting technical information.
Do not publish a single definitive voltage/current specification without confirming the actual unit.
⚠️ Trap #2 — Confusing LC1000-SSP7 with a generic ABB drive.
Several aftermarket pages call it a motor drive, while others call it a control module. The exact physical unit and nameplate must be used to establish its function.
⚠️ Trap #3 — Ignoring the original application.
For a legacy board, the machine model and installed cabinet location can be as important as the part number.
PRO TIP: For an RFQ, use:
ABB LC1000-SSP7 — exact replacement required; verify complete ABB ordering number, hardware revision, physical configuration, and original equipment application before shipment.
Dynamic FAQ
What is ABB LC1000-SSP7?
It is a legacy ABB LC1000-series industrial component. Secondary sources commonly describe it as a control/monitoring module, but other listings give conflicting classifications.
Is LC1000-SSP7 an ABB PLC?
It should not automatically be classified as a conventional PLC CPU. Available sources describe different functions, so the exact hardware configuration should be confirmed from the nameplate and original equipment.
Does it use 24 VDC?
One detailed listing specifies 24 VDC, but conflicting listings provide other electrical specifications. Therefore, verify the actual unit before applying power.
Does LC1000-SSP7 support PROFIBUS?
Some secondary listings claim PROFIBUS DP, but this should be verified against the exact hardware revision and connector configuration.
Is refurbished LC1000-SSP7 suitable as a spare?
Yes, provided the replacement is positively identified and functionally tested against the original application. For this particular part number, variant verification is especially important because publicly available specifications conflict.
What should I send a supplier?
Send a clear photograph of the entire LC1000-SSP7 unit, nameplate, PCB markings, connectors, and the cabinet location/equipment model. This gives the supplier enough information to distinguish the actual variant before shipment.
