Parijat Subsea Controls Communications Engine PLC NGC-1008

Parijat Subsea Controls Communications Engine PLC is a very versatile, scalable, end-user programmable embedded system. It can withstand depths of over 8000 Ft. in a dielectric oil uncompensated pressure container. Though designed for high demanding Subsea apps, can also be used for regular PLC and communications uses as well.



  • Complete UI as HMI and system configuration available.
  • Any input signal can be user software connected with any output signal via UI.
  • Suitable for subsea use at 8k Ft depth & 4K PSI. 0-50 C temperature.
  • Immersed in dielectric oil for water ingress protection, exposed to the high pressures.
  • Include the connectors (plug-in) and cabling to the inside of enclosure box. Use 10 pins typical.
  • Supports extensive board HW diagnostics accessible to software running on it.
  • Conformal coating for water protection.
  • MTBF 99%. Mechanism to test/debug during development via IDE.
  • Not expected to be in explosive environments – contact PCI if needed.
  • Retains configuration during power loss.
  • Power 24 VDC. May switch source during use. Smooth wake up/sleep of power use.
  • Temperature reading of the CPU board.
