Description
Product Introduction
⚙️ Product: IS410STCIS2A
🏷️ Ordering Reference: IS400STCIS2AFF
🔧 Brand: GE
🛡️ Series: Mark VIeS Functional Safety System
📡 Product Type: Compact Contact Input Terminal Board
The GE IS410STCIS2A is a Mark VIeS Compact Contact Input Terminal Board designed to interface field contact signals with the GE safety control system. It provides 24 contact input channels and is used with the IS420YDIAS1B contact input I/O pack. GE documentation identifies the IS410STCIS2A as the Mark VIeS 24 VDC Contact Input terminal board.
🔌 The board accepts a nominal 24 VDC wetting voltage and provides signal conditioning, noise suppression, diagnostic functions, and field wiring termination. It is designed for simplex applications and supports sequence-of-events acquisition with a documented 1 ms SOE sample rate.
🏭 Typical applications include turbine control, emergency shutdown logic, safety interlocks, power-generation equipment, and other industrial systems requiring reliable discrete contact monitoring.

Installation & Use
🛠️ Before installation, verify the IS410STCIS2A board revision, IS420YDIAS1B I/O pack compatibility, 24 VDC wetting supply, terminal assignment, and Mark VIeS configuration.
🔌 Mount the terminal board on the specified DIN rail or approved mounting arrangement. Connect field contact wiring according to the system drawings and verify the wetting-voltage supply before energizing the circuit.
📊 After startup, check the I/O pack LEDs and controller diagnostics. Verify all 24 input channels, contact states, SOE events, and communication status.
⚠️ This board can be used in safety-related Mark VIeS applications. Perform the required loop checks and functional verification before returning the turbine or safety system to service. GE documentation identifies the STCI terminal board as safety-rated and compliant with IEC 61508.
