A new explosion proof alarm annunciator, suitable for use in Zone 1 and Zone 2 hazardous areas, offers a vast range of features and benefits normally reserved for use in safe area annunciators only.
RTK Instruments' PEX7250 explosion proof alarm annunciator, suitable for use in Zone 1 and Zone 2 hazardous areas, offers a vast range of features and benefits normally reserved for use in safe area annunciators only.
The heart of the system is RTK Instruments' field-proven Series 725 alarm annunciator, which uses multiple-redundant ASIC technology to greatly improve reliability compared with conventional systems.
As annunciators are often used to monitor critical plant alarms, it is essential that the unit provides the highest reliability possible.
The use of ASICs removes any reliance on common control cards as all alarm cards in the annunciator can act as the master controller.
This high level of reliability is backed up by RTK Instruments' 5 year warranty.
The standard enclosure is copper-free cast alloy and finished in a light grey two-part epoxy paint, making it ideal for offshore applications.
A stainless steel enclosure is available as an option.
The PEX7250 alarm annunciator is available in a range of sizes and shapes from one to 56 points in a single enclosure, with a choice of three window sizes.
Illumination is using high reliability, ultrabright LEDs.
The annunciator is fully field programmable for all standard ISA sequences for alarm annunciation and further options are available, such as individual repeat relays per channel and RS485 serial interface.
Units are equipped with dual group relays and dual horn relays as standard.
For total programmability, reliability and flexibility in hazardous areas, RTK Instruments' PEX7250 can provide the ideal solution.
