Intended application

The NEMS is a new value, first value and process indicator system consisting of individual NEMS16 devices, each with 16 indicator inputs. By networking via a LAMTEC SYSTEM BUS, it is possible to create an indicator system with a maximum of 1024 signals (64 individual devices). Each indicator input (DC18-30V) can be converted to fault or process status signal as well as normal open or closed contacts and is displayed by means of a luminous, three-colour LED on the front panel.

When an indicator input is switched to the active state, the relevant LED changes over to a flashing light or a continuous light.

It is also possible to print out the signals in chronological order via a serial logging printer or a display and operating terminal connected at the LAMTEC SYSTEM BUS.

The device contains a real-time clock, which is synchronised with another NEMS16 in the system.

Applications

• Process monitoring
• Monitoring of safety interlock chains in combustion engineering
• Chronological recording and processing of fault values and operating data. Coupling to standard field bus systems (e.g. Profibus) is possible as an option.
• Logging and further processing in conjunction with higher-level computer systems.
• Decentralised recording of locally distributed signals.

Applications

• Panel installation
• Design for wall mounting
• Design as 19"-rack
• Message text and configuration software

accessories

• Display and operating terminal
• Radio clock
• Field bus link
• Printer
• Digital output module
• External horn

Applications and accessories detail

  Application: Panel installation

Standard panel installation housing made of black sheet steel with bezel.

Dimensions (h x w x d): 144 mm x 72 mm x 200 mm.

A plastic film with integrated sealed keypad covers the front of the device.

This film also contains a pocket into which the labelling strips can be inserted.

Electrical connection is made to plug-in terminals at the back.

Removing the front and detaching the connectors can extract the electronic unit.
