Description
The SILASpz Ex p control unit controls and monitors the purge and operating phase of pressurized enclosure equipment protected in accordance with ignition protection type pzc.
Digital or proportional purge gas valves can be used. The parameters can be set using the integrated WEB interface or the optionally available p operator panel.
The SILASpz 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 pprotected equipment. Up to three switch values can be assigned to them. Model II comes complete with integrated pressure measurement. The following components are additionally required to set up a complete control system:
- Pressure monitor
- Purge gas valve, proportional or digital
- Valve fuse
- Pressure reducer
- There is the option to connect a p operator panel
