Description

The APEXpy Ex p control unit controls and monitors the pre-purge and operating phase of pressurised enclosure equipment protected in accordance with ignition protection type py. Digital or proportional purge gas valves can be used as purge gas valves. The parameters can be set using the integrated WEB interface or the optionally available p operator panel. The APEXpy 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. Model I comes complete with separate pressure measurement.

The following components are additionally required to set up a complete control system:
– Sensor boxpx
– Pressure monitor
– Purge gas valve, proportional or digital
– Valve fuse
– Pressure reducer
– There is the option to connect a p operator panel
