Specifications Requiring Verification
The following values appearing on some reseller pages should not be accepted as engineering specifications without an OEM drawing or the installed board documentation:
- Number of signal channels
- Servo-valve output current
- LVDT channel count
- Acoustic-monitoring inputs
- 28 VDC supply requirements
- 16-bit resolution
- Exact operating temperature
- Connector pinout
- Input/output impedance
- Isolation ratings
For example, one source calls the part a Mark VI servo amplifier and publishes ±200 mA outputs and two LVDT channels, while another identifies it as an acoustic-monitoring terminal/interface board with 18 dynamic inputs. A separate listing incorrectly describes it as a 100–240 VAC/24 VDC power module. These specifications are mutually incompatible.
Product Introduction
The GE IS210SAMBH2AA belongs to the GE Mark VI turbine-control hardware family and is associated with the SAMB card assembly. The closely identified IS210SAMBH2A assembly is described as a DIN-mounted SAMB card assembly, making the complete part number and physical assembly configuration important when selecting a replacement.
For maintenance procurement, this is a part where the nameplate and host assembly should take precedence over generic online specifications. The H2A hardware designation and AA suffix should be matched exactly, particularly where the board forms part of a configured turbine-control cabinet.

Application Scenarios & Field Pitfalls — Engineer’s Perspective
Engineering Pain Point
The primary risk with IS210SAMBH2AA is misidentification. Several published descriptions assign completely different functions to the same part number, so purchasing based only on a search-result description can result in receiving a physically similar GE board with the wrong electrical function.
Typical Applications
- GE Mark VI Turbine Control Cabinets — installed as part of configured GE turbine-control hardware.
- DIN-Mounted Control Assemblies — the IS210SAMBH2A family is specifically identified as a DIN-mount card assembly.
- Turbine Control System Maintenance — used as a replacement assembly when the installed hardware matches the same SAMB configuration.
- Legacy GE Speedtronic Spare Parts — appropriate for controlled replacement programs where the original board identification is available.
Technical Pitfalls to Avoid
- Do not classify the part from the word “SAMB” alone.
Current listings attach several incompatible functions to this number. Confirm the board marking, connector arrangement, and host equipment before purchasing. - Do not substitute another SAMB revision solely because the PCB appears similar.
The H2A revision and AA suffix are part of the identification. Hardware revisions can affect connector assignments, components, and system compatibility. - Do not rely on unverified electrical specifications.
Claims such as ±200 mA servo output, 18-channel acoustic input, 32-channel digital input, or 240 W power conversion appear in conflicting listings. None should be used for engineering design without supporting GE documentation. - Compare the physical assembly before installation.
Check terminal arrangement, connectors, mounting hardware, board revision, cable routing, and any daughter-board or terminal-board relationship against the removed assembly.

- IS210SAMBH1A — related SAMB hardware designation reported in secondary documentation; verify function and revision before substitution.
- IS220UCSAH1A — Mark VIe processor/I/O hardware appearing in sources that discuss acoustic-monitoring applications; not a direct substitute for the SAMB assembly.
- IS220PAICH1A — Mark VIe analog input I/O Pack; different hardware function and architecture.
- IS220PTCCH1A — Mark VIe thermocouple I/O Pack; not a replacement for the SAMB assembly.
- IS200TBCIS2C — GE Mark VI/VIe terminal-board family; application and wiring must be verified before considering any interface relationship.
Procurement Note
For a GE IS210SAMBH2AA, provide the complete number rather than ordering from a generic description such as “servo amplifier” or “digital input module.”
Before accepting a replacement, compare the GE nameplate, board artwork number, H2A revision, AA suffix, connector layout, mounting arrangement, and host cabinet documentation. If the removed board is available, photographs of the component side, connector side, and nameplate can resolve the remaining identification uncertainty far more reliably than reseller specifications.
Bottom line: the defensible identification is a GE Mark VI SAMB card assembly in the IS210SAMBH2A DIN-mount family. The detailed functional/electrical claims currently published for are too contradictory to present as verified specifications.
