STAHL 8621A\u003Cbr>The Ex p system 8621 is ideal for safe control and monitoring of Ex p control cabinets in a range of sizes. The highly accurate pressure sensors, which are redundantly present for the Ex Zone 1 version, enable operation near the pressure switch-off threshold. This reduces the required leakage quantities to a minimum and guarantees very cost-effective continuous operation.\u003Cbr>The concept with a modular system component structure enables purge times and purge pressures to be adapted to meet current requirements. To do so, only the number of purge gas outlets (Ex p pressure monitors) needs to be changed in order to drastically reduce the purge time or purge pressure, if the same Ex p controller is used.\u003Cbr>To guarantee that adverse environmental conditions can be withstood, our tried-and-tested glass fibre reinforced polyester has been selected as the enclosure material. Additionally, optional suitable protective collars are available as protection against heavy rainfall.\u003Cbr>A device as simple as it is effective (Ex p vortex air cooler) is available for cooling Ex p cabinets. In this respect, too, the cooling power is regulated solely by the number of structurally identical devices that are installed.\u003Cbr>Technical Data |  |  |\n| Explosion Protection |  |  |\n| Application range (zones) | 2, 22 |  |\n| IECEx gas certificate | IECEx TUR 19.0033 X |  |\n| IECEx gas explosion protection | Ex ec mc ia [pzc Gc][ia Ga] IIC T4 Gc |  |\n| IECEx dust certificate | IECEx TUR 19.0033 X |  |\n| IECEx dust explosion protection | Ex tc [pzc Dc][ia Da] IIIC T80 °C Dc |  |\n| ATEX gas certificate | TUV 19 ATEX 8339 X |  |\n| ATEX gas explosion protection | E II 3 (1) G Ex ec mc ia [pzc Gc][ia Ga] IIC T4 Gc |  |\n| ATEX dust certificate | TUV 19 ATEX 8339 X |  |\n| ATEX dust explosion protection | E II 3 (1) D Ex tc [pzc Dc][ia Da] IIIC T80 °C Dc |  |\n| Certificates | ATEX (TUR), Brazil (ULB), China (CQST), IECEx (TUR), India (PESO), Korea (KTL) |  |\n| Declaration of conformity | ATEX (EUK) |  |\n| Further information | See the operating instructions for the Ex p system |  |\n| Auxiliary Power |  |  |\n| Aux. power rated oper. voltage | DC 24 V (+20% ... 15%) |  |\n| Note | Rated current depends on the Ex p purge valve used |  |\n| Auxiliary power connection | Screw connector |  |\n| Device Specific Data |  |  |\n| Min. pressure range | 0 mbar |  |\n| Max. pressure range | 25 mbar |  |\n\n2026-08-08 R.
