Latest releases:

New Pageant Intrinsically Safe Operator Panel - HMI, PLC, Modular I/O & Comms

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. Common uses include the control and monitoring of pharmaceutical coating machines, mud pumps, flammable liquid stills, batch control for filling and emptying, plus milling and mixing in combustible dust atmospheres.


Ex eb and Ex tb 4/20mA Loop Powered Indicators - Lower cost alternative for flameproof Ex d indicators

Ex eb certified indicators are a lower cost alternative to flameproof Ex d indicators, featuring large high contrast displays with a very wide viewing angle. They may be connected into any 4/20mA Zone 1 or 2 loop with any type of explosion protection apart from intrinsic safety.

The indicators also have dust ignition protection by enclosure Ex tb allowing installation in Zones 21 and 22.
