This certificate is issued as verification that a sample(s), representative of production, was assessed and tested and found to comply with the IEC Standard list below and that the manufacturer's quality system, relating to the Ex products covered by this certificate, was assessed and found to comply with the IECEx Quality system requirements. This certificate is granted subject to the conditions as set out in IECEx Scheme Rules, IECEx 02 and Operational Documents as amended.
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.
Solenoid Coil Drivers Model HiC2873(Y1) and Model HiC2877 are isolated barriers for the supply of intrinsically safe devices as solenoids, LEDs, audible alarms, located in an explosive atmosphere.The modules mount into a HiC Termination Board.Ambient temperature range -20 ºC to +60 ºC.Electrical dataSupply:20.4 ... 30 V (via Termination Board, or via loop powered input (except Model HiC2873Y1)),rated current maximum 62 mA (at 24 Vdc),power maximum 1 W.Control input:external switch (dry contact or open collector), logic signal.For the data of the intrinsically safe output circuit, refer to Certificate of Conformity IECEx CES 10.0017.
The modules shall be installed in an enclosure or cabinet that at least is in compliance with the requirements of the standards listed and that provides a degree of protection of at least IP54.Provision shall be made externally to provide transient protection, set at a level not exceeding a peak voltage of 119 V.The modules may only be disconnected from or connected to the HiC Termination Board if the system is de-energized or if no explosive atmosphere is present.The use of operating elements is only allowed if the system is de-energized or if no explosive atmosphere is present.
