2.1 System Features
• Modular system
• 19” rack system for the connection of up to 256 sensors
• Complete system for up to 64 sensors with common relays (Alarms 1–4, signal fail, horn,
inhibit, power) in one 19” rack
• Maximum number of switching outputs in the system: 512
• Minimal installation work (bus system)
• Redundancy possible
• Maximum refresh rate of 3–4 seconds for alarm outputs (1–2 s for data acquisition; 1 s for
computation; 1 s for data output)
• Maximum refresh rate of 3–5 seconds for signal fail outputs (1–2 s for data acquisition; 1–2 s
for computation; 1 s for data output)
• Maximum response time of 15 seconds for system fails
• External voltage operation (85–265 VAC) no switching necessary
• Power supply unit on the rack, 250 W
• For higher power requirements, external power supplies can be connected
• Battery connection for emergency power operation
• Operating voltage range of the system modules: 19.2 VDC–32 VDC.
Recommended voltage: 24 VDC.
• Universal sensor interface with automatic sensor detection
• Operation of passive catalytic/semiconductor sensors, 3- or 5-wire.
• Automatic pre-setting of passive detectors in first calibration
• Operation of active transmitters with 4–20 mA output, 2- or 3-wire
• System operation via a graphical touch screen with a resolution of 320 x 240 pixels and indi-
vidual function keys
• Self-explanatory error messages
• System configuration and parametrization optionally via laptop (Windows user interface)
• The SUPREMATouch can be connected via a bus connection to the company communications
network (data evaluation, data display, etc.)
• Key switch connection or three password levels to control access
• Key switch connection for relay inhibiting
• Remote key switches for acknowledgment and reset
• Common alarm LEDs for 1st to 4th alarm, signal fail (sensor), system fail, inhibit, power supply
fail
• Protocol printout of status c system operations (standard ASCII, 80 CHR)
• 1 x USB + 1 x RS232 or 2 x RS232 interfaces for data transfer to an industrial PC/laptop/printer
• RS232 interfaces are electrically isolated
• RS232/RS485 converters used for longer transmission distances
• 8 MRO Module common alarm relays supplied by the rack power supply unit
• External relays are supplied with power separately
• Recommended operational lifetime according to EN 50271: 20 years
