GE IS220UCSAH1A-C

Product Introduction: The GE IS220UCSAH1A-C is a variant of the IS220UCSAH1A embedded controller module for the Mark VIe system. The “-C” suffix denotes a conformal-coated version, providing enhanced protection against moisture, dust, and chemical contaminants. It retains the same processor, memory, and operating system as the base model while extending suitability to more aggressive industrial environments.

Description

GE IS220UCSAH1A-C

Technical Specifications:

  • Series: GE Mark VIe Speedtronic
  • Processor: Freescale 8349, 667 MHz
  • Memory: 256 MB SDRAM
  • Storage: 1 GB CompactFlash
  • Operating System: QNX Neutrino
  • Power Supply: 18–36 V DC, 12 W
  • Operating Temperature: 0 °C to 65 °C
  • Hazardous Location Rating: NFPA Class I, Division 2
  • Coating: Conformal coating on PCB for environmental protection
  • Front Panel: Six Ethernet jacks, one USB port, LED indicators (Link/Act, Power, Boot, Online, Flash, DC, Diag)
  • Dimensions and Weight: Similar to IS220UCSAH1A base model

Functional Features:

  • All functions of the IS220UCSAH1A base model
  • Conformal coating protects circuitry from humidity, corrosive gases, and conductive dust
  • Suitable for tropical, coastal, or chemically aggressive industrial environments
  • Maintains triple-redundant (TMR) mounting capability with up to three side-by-side modules
  • Fanless natural-convection cooling retained

Application Scenarios:

  • Gas and steam turbine control in coastal or high-humidity power plants
  • Petrochemical facilities with corrosive atmospheres
  • Offshore platforms requiring enhanced environmental protection
  • Industrial sites with conductive dust or chemical contamination

Performance Parameters:

  • Processor performance, memory capacity, and communication interfaces identical to the base model
  • Coating does not affect thermal performance under specified operating conditions
  • Reliability extended in harsh environments due to moisture and contaminant protection

Material and Structural Characteristics:

  • Industrial-grade PCB with conformal coating applied to critical circuitry
  • Aluminum or steel housing with grille openings for natural cooling
  • Front panel with Ethernet jacks, USB port, and LED indicators
  • Mounting via two rear screw mounts

Working Principle: The IS220UCSAH1A-C operates identically to the base IS220UCSAH1A, executing application code under QNX Neutrino and communicating with I/O packs over IONet. The conformal coating provides an additional protective barrier on the PCB without altering the electrical or functional behavior of the controller. Installation Requirements:

  • Mount inside a control cabinet using rear screw mounts
  • Preserve unobstructed airflow through grille openings
  • Connect 18–36 V DC power and Ethernet cabling
  • Configure using ToolboxST
  • Avoid abrading or scratching the conformal coating during handling or maintenance

Usage Notes:

  • The conformal coating extends service life in harsh environments but does not eliminate the need for proper enclosure protection
  • Inspect coating integrity during scheduled maintenance
  • Use compatible cleaning agents that will not degrade the coating
  • Confirm firmware and software compatibility with the Mark VIe system version
  • Follow ESD precautions despite the protective coating
