Chapter 2 The AADvance Safety Controller
KCC-EMC Registration
Main Components
An AADvance controller is built from durable processor and I/O modules and
assemblies designed to IEC 61508 standards for safety systems and runs the
AADvance Workstation software. Field devices connect direct to a controller
and external communication links over Ethernet and serial links use a secure
protocol.
Physical Features A new and innovative style characteristic of the AADvance controller is the
design of the hardware. All the modules and assemblies connect together easily
without the need for inter-module wiring.
Compact Module Design
Each processor and I/O module has a flame-retardant and impact-resistant
plastic cover. The cover is designed to help ventilation and heat dissipation
occur naturally without the need for fan assisted cooling. Processor and I/O
modules fit onto standardized base units. Base units plug together by side
connectors and are securely held in position by specially designed plastic clips
which cannot corrode or seize up. Modules are retained by a locking screw
which is easy to access from the front.
CAUTION: The controller contains static sensitive
components. When the controller is installed attach a label
that is clearly visible to tell operators to follow anti-static
precautions when they touch or move modules. Failure to
follow these instructions can result in damage to the
equipment.
