GE IC660BBA104 | 6231BP10910 Genius 4–20 mA Analog I/O Module

Description

Key Technical Specifications

GE’s Genius manual explicitly lists IC660BBA104 as a four-input/two-output current-source analog block and identifies IC660TBA104 as its terminal assembly and IC660EBA104 as the electronics assembly.

The block accepts 115 VAC or 125 VDC, while the field signal circuits use 4–20 mA. The architecture also supports independent linear scaling so raw signal values can be represented as application engineering units.

Application Scenarios & Pain Points

With older Genius installations, analog faults can be deceptively expensive. A single bad channel may affect flow control, level regulation, pressure indication, or valve positioning while the controller itself continues executing normally.

• Process measurement: Four 4–20 mA inputs can interface transmitters for pressure, flow, temperature, level, and similar process variables.
• Valve and actuator control: Two current outputs provide 4–20 mA signals to compatible control elements.
• Legacy GE distributed I/O: The block communicates over the Genius bus, making it suitable for older GE Fanuc distributed-control architectures.
• Redundant bus installations: A dedicated digital output supports control of a Bus Switching Module when the block is installed in a redundant bus-cable arrangement. The manual specifies the IC660BSM021 for the 24/48 VDC BSM function.

Field note: If one analog channel suddenly reads zero, do not immediately replace the block. Check loop power, transmitter output, terminal connections, and the Genius configuration first. A loose terminal screw can create a very convincing “bad analog card” symptom.

The Engineer’s Guide: Field Pitfalls to Avoid

⚠️ Do not confuse with IC660BBA024.

Both are current-source analog blocks with four inputs and two outputs, but their power requirements differ. is the 115 VAC/125 VDC version, while IC660BBA024 is the 24/48 VDC version.

How to avoid it: Check the actual control-panel supply wiring before approving a substitute.

⚠️ Do not order IC660EBA104 when the complete block is required.

The IC660EBA104 / 6231BP10920 is the electronics assembly associated with the block. The complete block uses the terminal assembly and electronics assembly together.

How to avoid it: Confirm whether the failed item is the complete field block or only its electronics assembly.

⚠️ Do not overlook Genius configuration and analog scaling.

The block can apply independent linear scaling, and its data is exchanged as engineering-unit values through the Genius communication system. Replacing hardware without preserving configuration can produce apparently incorrect process values.

How to avoid it: Record Genius bus configuration, channel scaling, input/output ranges, and controller-side configuration before removing the original block.

Frequently Asked Questions (FAQ)

What is GE 6231BP10910?

It is a Genius I/O current-source analog block providing four 4–20 mA inputs and two 4–20 mA outputs. The 6231BP10910 identification corresponds to this GE assembly.

What voltage does require?

The is the 115 VAC / 125 VDC version of the current-source analog block. GE also produced the IC660BBA024 for 24/48 VDC applications.

How many analog channels does have?

There are four analog current inputs and two analog current outputs, all intended for 4–20 mA signals.

Does require a separate power supply for 4–20 mA transmitters?

The Genius documentation states that the current-source analog block provides isolated power to its circuits, so separate external power is not required for the block’s 4–20 mA signal circuits.

Is 6231BP10910 the same as ?

Yes. The available documentation and product references associate 6231BP10910 with . For purchasing, list both identifiers because the GE catalog number and the associated assembly/order number may appear separately in older drawings.

Can I replace with IC660BBA024?

Not as a direct electrical substitution. The two blocks have the same general 4-input/2-output 4–20 mA architecture, but their supply-voltage classes differ. Verify the cabinet supply and system design first.

What should I verify when purchasing a replacement ?

For a legacy-system spare, I would verify:

2. 6231BP10910
3. 115 VAC / 125 VDC supply arrangement
4. Four-input/two-output configuration
5. 4–20 mA field wiring
6. Terminal assembly condition
7. Genius bus configuration
8. Channel scaling parameters
9. Hardware revision
