Impressed Current Cathodic Protection (iCCP) station tKs-a-t is a microcontroller (with arm7 core) based device featuring a complete set of functions:

•  Output current is automatically adjusted according to measured reference potential, current or voltage.
• Integrated data logger collects data records at preset rate. Each data record contains
  time stamp the record was taken, measured and setpoint reference potential,
  current and voltage. Also in the record are stored controller status and events such
  as door openings and power failures.
• Integrated telemetry enables remote confi guration and monitoring. Direct or
  modem connection is used to transfer data using standard communications
  protocol in industry – Modbus. Usually data interchange session is initialized by
  remote host, but TKS-A-T station also can take that role in case of critical event
  such as power failure. Over data interchange session TKS-A-T station confi guration
  can be remotely downloaded or uploaded as well as collected records can be
  downloaded.
• Measured and setpoint values of reference potential, current and voltage can be
  seen on TKS-A-T station panel all at once. Reference potential, current and voltage
  setpoints can be manually edited with simple keyboard. Optionally, manual edition
  can be forbidden remotely by the host.
• Relay-based rectifi er output disconnecting function. This can be accomplished
  manually with keyboard or remotely by host. This function is valuable for protected
  object maintenance services such as welding.
• Backup supply allowing to keep device functional (except output current) during
  main power supply failures. Modem backup is also provided.
