2.1 Introduction
The SUPREMA control system, which is used in the area of gas measuring technology, is
characterised by the following properties:
• modular system design
• compact construction
• highly flexible
• minimal installation work (bus system)
• high availability
At the maximum degree of expansion, 256 sensors can be connected. The system can drive
up to 512 relay outputs.
For higher safety levels, the system can be built with redundancy.
Via a CAN bus interface, an industrial PC can be connected to tie the system into the company
communications network, for example.
2.2 Features of the System
• 19” rack system for the connection of up to 256 sensors.
• Output of up to 512 alarm messages.
• Complete system for up to 64 sensors with common alarm in one 19” rack.
• Modular system.
• Compact construction.
• High flexibility.
• Minimal installation work (bus system).
• External voltage operation (85 ... 265 VAC) no switching necessary.
• Power supply unit on the rack, 150 W.
• For higher power requirements, external power supplies can be connected.
• Battery connection for emergency power operation.
• Operating voltage of the modules = 24 VDC; voltage controller for 5 V, etc., on the
modules.
• The system is laid out so that card coding is no longer necessary.
• Operating voltage range of the system modules: 19.2 VDC ... 32 VDC.
• Operation of passive catalytic-/semiconductor-sensors (D-7600, D-7100, D-7010, etc.),
3- or 5-wire.
• Operation of active sensors with 4 ... 20 mA output, 2- or 3-wire (DF-7100, DF-9500,
etc.).
• Maximum number of sensors in the system: 256.
• Maximum number of sensors in one rack: 64.
