Description
The GE IS410STAIS2A is a Mark VIeS Simplex Analog I/O Terminal Board used with the IS420YAICS1B Analog I/O Pack. It provides the field interface for analog process signals and supports 10 analog inputs plus 2 analog outputs, for a total of 12 channels. GE documentation confirms the board as an active Mark VIeS safety-system component.
The IS400STAIS2AED is also associated with this STAI terminal-board assembly in industrial listings. When purchasing a replacement, the physical nameplate, hardware revision, and existing I/O Pack configuration should be checked carefully rather than treating every similarly named board as interchangeable.

🏭 Typical Applications
The IS410STAIS2A is intended for industrial safety and control applications such as:
• Gas turbine control
• Steam turbine control
• Power generation
• Process automation
• Generator monitoring
• Industrial safety systems
• Analog transmitter monitoring
• Mark VIeS functional-safety installations
⚡ Functional Description
The STAI terminal board provides the physical connection between field analog sensors/actuators and the YAIC I/O Pack. Its ten analog inputs can accept different transmitter wiring configurations, while the two analog outputs provide 0–20 mA signals to compatible field devices.
An onboard identification chip allows the I/O Pack to identify the terminal board for system diagnostics. GE also specifies power-up self-testing, continuous internal power-supply monitoring, incorrect-terminal-board detection, analog input limit checking, and analog-output health monitoring.
🔌 Installation & Configuration
Basic installation procedure:
• Verify IS410STAIS2A / IS400STAIS2AED identification
• Confirm Mark VIeS system compatibility
• Check the installed IS420YAICS1B I/O Pack
• Mount the terminal board on the designated DIN rail
• Connect field wiring according to the project drawings
• Verify transmitter wiring type
• Configure AI and AO channels in the control system
• Restore power and check diagnostic status
🛠️ Commissioning Checklist
• Confirm board identification
• Check I/O Pack connection
• Verify all field terminals
• Check 4–20 mA / 0–20 mA signals where applicable
• Verify voltage-input channels
• Confirm analog output operation
• Check diagnostic indicators
• Review controller alarms
• Compare process values with calibrated field instruments
⚠️ Replacement Note
The IS410STAIS2A is specifically documented by GE as the Mark VIeS Simplex Analog I/O terminal board. Some secondary listings describe the part as an STCI board or simply an analog output board, but GE’s own documentation identifies its actual function as the STAI analog I/O terminal board with 10 AI + 2 AO.
