Zone 1 intrinsically safe combined operator panel, PLC and I/O modules

26 June 2023

Pageant is an intrinsically safe combined operator panel, HMI and PLC which can be installed in Zones 0, 1, 2, 20. 21 or 22. It can accommodate a plug-in CPU module and up to 7 plug-in intrinsically safe input and output modules.

The operator display and all of the plug-in modules have individual Ex ia apparatus certification allowing low cost PLC systems to be constructed without the need for additional certification. Pageant can operate alone, or as part of an integrated system to provide economical monitoring, control and communications for a vast range of hazardous area applications.

Pageant comprises an industry standard CODESYS® IEC 61131 compliant PLC, plus a seven inch back-lit operator display which is readable in all lighting conditions. An increasing range of plug-in analogue and digital input and output interface modules, plus a CPU module with optional external communications enable systems to be constructed with just the required functions. Operator inputs are made via eight touch buttons which incorporate programmable tricolour annunciators.

Intrinsic safety provides users with the safest hazardous area protection. This new BEKA low power technology eliminates the need for a heavy protective enclosure, reduces cost and allows the back-lit display and modules to be powered from a single BEKA Power Isolator. The BA3101 display and each of the plug-in interface modules have individual international apparatus certification with common interface safety parameters allowing users to only purchase the modules required for their application. If circumstances change, additional modules can be fitted and configured on-site.

Communication with Pageant is via an isolated RS485-IS port which can be connected to other equipment in the hazardous area, or to the safe area via a proprietary Isolator. Modules for Modbus are already available with others being developed.

Panel mounting Pageant has a toughened glass display window surrounded by a 316 stainless steel bezel providing IP66 ingress protection and a flat easy to wipe clean surface.
