Description
The APEXmv Ex p control unit controls and monitors the purge and operating phase of small, separate, pressurized enclosure equipment protected in accordance with ignition protection type pxb.
The parameters can be set using the integrated WEB interface or the optionally available p operator panel. The APEXmv features two release relays; one which is energised and one which has floating contacts. Two signal relays with one changeover contact each are additionally available.
Three PT100/1000 inputs are available to monitor the temperature of the Ex p-protected equipment. Up to three switch values can be assigned to them.
The design of the APEXmv means that all components required for the pressurised enclosure are located in the control unit. The equipment to be monitored is connected to the Ex p control unit by means of a pipe, which allows a maximum purge volume of 70 litres.
The following components can also be connected:
- Option to connect a p operator panel
- Option to connect additional pressure sensors
