美国诺南(Ronan)报警显示产品

X16分体式报警器
The Visual Annunciator System architecture, configured where the electronic modules are remote from the window display, is ideally suited for large systems in power plants and process plant control rooms. The modular logic is housed in relay rack-mount or surface-mount chassis, and connected via multiconductor wiring to the lamp display. Connection to the display and the logic chassis may be made by means of individual wires to terminals; or via prefabricated cable assemblies with multipin connectors. The split architecture provides ease of maintenance with access to the electronics without interference with the control room operation.

X19 系列单点报警器
These self-contained alarms provide complete annunciation capability for NEMA 4 or 12 Applications. Each alarm contains the necessary logic, light indicator, and pushbutton switch for single point monitoring of Normally Open or Normally Closed field contacts.

X3系列继电器报警系统
The relay logic based alarm annunciator systems are preferred in applications where extreme environmental conditions are encountered. The combination of proven reliability, noise immunity and simplicity of the logic circuits makes the relay system ideally suited for applications on oil platforms, desert or arctic environments, shipboard, or any place with limited technical support. The alarm modules feature normally open/normally closed field contact selection, auxiliary contact outputs, lock/non-lock selection, and are available in all major ISA 18.1 sequences, as well as a number of custom sequences

X12系列固态报警装置
The X12 system provides for single point alarm logic modules driving TWO incandescant lamps or LED Arrays based window display from single to quad arrays per mechanical modules.

X11系列固态报警装置
The X11 and X11SN multipoint systems feature alarm modules with on-board alarm logic for single, dual, tri, and quad windows, lit by two incandescent lamps or Light Emitting Diodes (LED) Arrays.
The alarm logic is designed to generate any of the ISA 18.1 alarm sequences and a large number of custom sequences. The logic is designed to meet IEEE 472 Surge Withstand Test and high noise immunity requirements.
On-board options, such as optoisolation for live AC or DC voltages, transistor inputs, time delays, selectable dual audible, ringback audible, short circuit proof lamp drivers, lamp dim, and dual colors are available.
Auxiliary function modules, such as auxiliary contact modules, may be integrated individually or in combination into the various systems.
