iMAC SYSTEM OVERVIEW
The iMAC system is an Integrated Monitoring and Control system designed specifically for long line
distributed monitoring and control in harsh hazardous areas such as mining and heavy industry. The system
is IECEx Ex ia Group I certified allowing use in intrinsically safe underground mining applications.
The iMAC system is basically a configurable logic controller, with fieldbus connected I/O modules. Modules
are simply multi-drop connected to the iMAC fieldbus which reach up 10km and beyond. Note: the maximum
length possible depends on a number of factors such as the number and type of modules connected, the
distribution of modules, and the fieldbus cable type. Ampcontrol has a number of optimised iMAC fieldbus
cables available to cater for your specific system requirements. Please consult with a qualified Ampcontrol
applications engineer whom will be able to discuss and advise the most cost effective cable to meet your
requirements.
Key Features:
Remote monitoring and control using a flexible range of I/O modules
Digital input modules (most input modules are powered directly from the fieldbus)
Relay output modules
Analogue input modules
Serial interface modules
Fault tolerant fieldbus with high electrical noise immunity
Advanced fieldbus diagnostics (including individual module loop resistance readings and individual
module communications error counters)
Fieldbus E/stop function qualifies for SIL2 or SIL3 applications
Intrinsically Safe Certification (IECEx Ex ia Group I)
Typical Applications:
Emergency Stop Systems
Overland bulk material conveyors (E/stop, Pullkey monitoring, belt drift/wander, belt tear, blocked
chute, sequencing, and remote isolation controls)
Underground mining conveyors (E/stop, Pullkey monitoring, belt drift/wander, belt tear, blocked
chute, sequencing, and remote isolation controls)
Underground mine wide gas monitoring systems (NERZ/ERZ systems, CH4, CO, CO2, O2, H2S
monitoring)
Longwall monitoring and control (AFC, BSL, E/stop, sequencing and remote isolation controls)
Coal prep-plant/washery monitoring
Rail network traffic monitoring
Any application that requires reliable monitoring and control of fieldbus I/O distributed over large
distances. Up to 10km and beyond can be achieved, subject to system configuration and cable type.
