ABB’s own CS31 documentation lists 07 EA 90-S under the EW8 analog-input configuration and identifies it alongside the other 07 EA 60/61/62/63/64/65/66/67 R1 analog-input modules. A separate ABB safety-system document identifies 07 EA 90-S R0101 as an analog input device.
Important Specification Limitation
Public sources frequently publish detailed electrical specifications for this part, but the available information is inconsistent. Some reseller pages incorrectly describe the same part number as a CPU, power supply, relay module, or a modern Ethernet/USB device. Those claims conflict directly with ABB’s CS31 documentation and should not be used for a replacement specification.
For a procurement document, the safest verified identification is therefore 07 EA 90-S / GJR5251200R0101 — ABB Procontic analog input module. Channel count, exact input ranges, resolution, accuracy, and supply requirements should be confirmed from the original module label or the applicable ABB 07 EA 90-S technical manual before being treated as installation specifications.
Product Introduction
The ABB 07EA90-SI GJR5251200R0101 is a legacy Procontic analog input module used to acquire analog process signals for an ABB Advant Controller 31 control system. ABB documentation places 07 EA 90-S within the analog-input configuration group, while independent product identification confirms the GJR5251200R0101 order number.
From a maintenance perspective, this is an I/O acquisition module rather than a CPU. That distinction matters when diagnosing a missing or incorrect analog value: the replacement must match the hardware configuration and the field-signal type, rather than simply matching the connector or physical dimensions.

Application Scenarios & Field Pitfalls — Engineer’s Perspective
Engineering Pain Point
The main risk with a legacy 07EA90-S replacement is incorrect identification. Several current reseller databases contain contradictory descriptions for GJR5251200R0101, including CPU and analog-input classifications. ABB’s own documentation provides the stronger reference and identifies 07 EA 90-S as an analog input device.
Typical Applications
- ABB Procontic PLC systems requiring analog process-value acquisition
- Advant Controller 31 installations using distributed I/O
- Legacy process-control cabinets where 07 EA 90-S remains part of the original I/O configuration
- Maintenance and replacement projects involving discontinued ABB hardware
Technical Pitfalls to Avoid
- Do not purchase it as a CPU.
is identified as 07 EA 90-S analog input, while central processing units use different designations such as 07 KT-series units. ABB’s documentation makes this distinction clear. - Do not rely on generic 4–20 mA or ±10 V claims without checking the original documentation.
Several reseller pages assign different input ranges and even contradictory specifications to this part. Treat those values as unverified unless they can be matched to the actual ABB documentation or module nameplate. - Check the configuration before commissioning.
ABB’s configuration documentation maps 07 EA 90-S to the EW8 analog-input configuration. The replacement therefore needs to be checked against the controller’s configured I/O structure rather than installed as an arbitrary analog card.

Procurement Check
Before approving an , verify:
- Exact designation: 07 EA 90-S
- Exact order number:
- ABB Procontic host system
- Existing configuration and EW8 assignment
- Original module revision and nameplate
- Actual field signal type and range
- Existing wiring and terminal arrangement
- Controller firmware/configuration
- Whether the replacement is new surplus, used, or refurbished
- Availability of a tested spare because this is legacy hardware
Recommended procurement description:
ABB 07 EA 90-S / 07EA90-SI Procontic Analog Input Module, ABB Advant Controller 31 Legacy I/O, EW8 Analog Input Configuration.
The critical identification is 07EA90-SI = 07 EA 90-S analog input module, not a CPU, power supply, or generic modern analog I/O card. ABB’s own documentation supports this classification, while several reseller databases contain conflicting descriptions that should be disregarded for engineering specifications.
