Product Overview

The IS210BAPAH1AREV‑C (BAPA) is a high‑density analog processor board for GE Mark VI / Mark VIe turbine‑generator control systems, hardware revision C. It acquires multi‑channel analog field‑signals including RTD bearing‑temperature sensors, thermocouples, 4‑20 mA pressure‑/flow transmitters, converts analog readings into digital values, and transmits data across the rack backplane to the main turbine‑controller for closed‑loop control, monitoring and alarm‑logic processing.

This board addresses turbine‑control challenges: high‑precision multi‑type analog‑signal acquisition for critical plant‑process loops, robust EMI‑rejection for high‑EMI turbine‑skid environments, and drop‑in spare‑part compatibility for legacy Mark VI / Mark VIe retrofit projects. Rev‑C includes component‑level upgrades compared with older Rev‑A/B versions for improved long‑term stability. Turbomachinery‑control engineers, power‑plant maintenance technicians and system‑retrofit integrators benefit most. It fits standard Mark VI rack slots and applies for gas‑turbine, steam‑turbine and combined‑cycle power‑generation unit temperature, pressure and flow monitoring loops.

Key Application Notes

• Must pair with corresponding analog termination panel and Mark VI/VIe main‑controller hardware; cannot operate standalone
• Supports RTD, thermocouple and 4‑20 mA analog input types; configuration is set within ControlST software
• Non‑hot‑swap hardware: rack power must be disconnected before board replacement
• Rev‑C is backwards‑compatible as spare replacement for IS210BAPAH1A Rev‑A / Rev‑B units
• No onboard field‑wiring screw terminals; field‑wiring is terminated on separate external termination hardware
• Conformal‑coated PCB as standard for Rev‑C variant, suitable for high‑humidity, high‑contaminant cabinet environments
• Widely used aftermarket spare for power‑plant turbine‑control maintenance and modernization‑retrofit projects
• Origin: USA
