Product Series
- Part of Mark VIe Terminal Board Family (compatible with EX21xx/IS20x/IS215 controllers).
Key Features
- Dual-Path Wiring: Dedicated terminals for redundant I/O packs.
- EMI Shielding: Metal casing with grounded backplate.
- Hot-Swappable: Replaceable without turbine shutdown.
- Color-Coded Terminals: Simplified wiring (green = safety, blue = analog).
- Fiber-Optic Ports: For communication with controller (via optional transceiver).
- Visual Indicators: LED status for power/signal integrity.
Functions & Roles
- Signal Routing: Bridges field devices (PT100, 4–20mA) to I/O packs.
- Galvanic Isolation: Prevents ground loops in analog circuits.
- Surge Protection: TVS diodes for transient voltage suppression.
- Safety System Integration: Interfaces with tripping modules.
- Diagnostics: Channel-level fault reporting via ToolboxST™.

Critical Notes:
- Safety Compliance: Requires redundant wiring per ANSI/ISA-S84.01.
- Voltage Limits: 300V peak field signals (derate above 60°C).
- Grounding: Dedicated chassis ground lug (min 4 mm² wire).
- Obsolescence: Part of legacy Mark VIe; upgrade path to Mark VIeS.
- Fiber-Optic Use: Only activates if paired with IS200FIBxx transceiver.
- Do Not Use: For vibration monitoring (requires dedicated VBAI boards).
