The APEXmpc Ex p control unit controls and monitors the pre-purge and operating phase of pressurised enclosure motors protected in accordance with ignition protection type px. The parameters can be set using the integrated WEB interface or the optionally available p operator panel. The APEXmpc 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. All the components required to set up Ex px monitoring and purge gas valves are integrated in the APEXmpc.
The following components are additionally required
to set up a complete control system:
– “Motor purge valve MPC” outlet
– There is the option to connect a p operator panel
