CI820: technical identity and handover
Identify CI820 by its complete marking before ordering. CI820 is a redundant AF 100 S800 communication interface within an engineered system, so the connection and project context matter as much as the family name.

Order-code questions
Before buying CI820, resolve this critical match: Check paired interface configuration, AF 100 modem and medium, firmware and power supply. Request an explicit statement of any hardware, firmware or accessory difference.
If another code is offered for CI820, compare it against the installed drawings and the manufacturer's variant data. Do not infer interchangeability from enclosure appearance or shared prefix.
Acceptance evidence
The site test for CI820 should include: Verify both paths and the approved switchover behavior without disturbing live process control. Save the observed values, status indications and responsible reviewer's approval.
For equipment containing CI820, document any parameter restore, wiring change, safety check or protective-setting check before release to normal operation.
System interface
CI820 serves this duty: Provide the redundant field communication path required by the existing S800 installation. Draw the path from supply or network through CI820 to the connected load or signal.
Record the real terminal positions, connected cable, controller or protection logic, and the environmental conditions around CI820. These define the acceptance boundary for a replacement.
