This Unit verification certificate is issued as verification that the Apparatus identified on page 1, was assessed and tested and found to comply with the IEC Standard list below. This certificate is granted subject to the conditions as set out in IECEx Scheme Rules, IECEx 02 and Operational Documents as amended.
The electrical apparatus and any acceptable variations to it specified in the schedule of this certificate and the identified documents, was found to comply with the following standards:
As this is a Unit Verification Certificate, no QAR is applicable as this certificate is specific to the items listed by serial number or other unique identification.
The 4-channel analog output, type AOH40Ex and AO41Ex, is part of the excom field bus system for the module racks, type MT... . In conjunction with this module rack unit, the 4-channel analog output may only be operated within the excom system. All modules are used to safely electrically isolate intrinsically safe field circuits of category "ia" from intrinsically safe bus and supply circuits of category "ib".
The field circuits are electrically isolated from the supply circuit and the CAN bus.
The ambient temperature range is –20 °C ... +60 °C.
For further information see schedule.
