Equipment and systems covered by this certificate are as follows

The D5212Q-xxx module is a galvanic isolator which provides intrinsically safe connections to four field devices (4-20mA transmitters) located in a hazardous area and repeats the transmitter current in the non-hazardous area. 2 channels are also able to accept 4-20 mA current signals from active (powered) transmitter. The DS5212Q is intended for installation in non-hazardous or Zone 2 hazardous locations. It consists of a single PCB assembly in a plastic enclosure suitable for DIN rail mounting or mounting on a termination board (not part of this evaluation). Electrical connections are by means of plug-in terminal blocks or via the termination board. The supply voltage can be optionally provided to the D5212Q by means of the optional Power Bus connector. An optically coupled, open-drain alarm output is also provided. The alarm trip point is settable by the user over the entire input signal range.

Please see Annex for additional information.

  • For installations in which both the Ci and Li of the Intrinsically Safe apparatus exceeds 1% of the Co and Lo parameters of the Associated Apparatus (excluding the cable), then 50% of Co and Lo parameters are applicable and shall not be exceeded. The reduced capacitance of the external circuit (including the cable) shall not exceed 1uF for Groups I, IIA and IIB and 600 nF for Group IIC.
  • Isolation in accordance IEC 60079-11 clause 6.3.13 is not provided between separate intrinsically safe circuits. Isolation in accordance with IEC 60079-11 clause 6.3.13 is provided between non-intrinsically safe circuits and intrinsically safe circuits.
  • For hazardous location, the unit shall be installed in a certified Ex enclosure with a minimum ingress protection of at least IP54 in accordance with IEC 60079-15, that must have a door or cover accessible only by the use of a tool.
  • The unit shall be installed in an area of not more than Pollution Degree 2 according to IEC 60664-1.
