The GG2 Display Module is an intrinsically safe apparatus for the purpose of displaying and transmitting sensor data and system information. The GG2 Display consists of a certified GG2 Display Module and associated wiring installed within an IP66 rated stainless steel enclosure. This document details the Modus and iMAC communication protocols.
The iMAC Slave Line Barrier (SLB) permits connection of non-intrinsically safe modules to an intrinsically safe iMAC fieldbus. The SLB barrier achieves this by accepting an intrinsically safe iMAC fieldbus connection at its L1 (input) terminals and creating a synchronised re-generated isolated non-intrinsically safe iMAC fieldbus at its L2 terminals (output).
The iMAC System has been approved as Intrinsically Safe for use in Group I mining applications. The iMAC Master Line Barrier (MLB) facilitates this by limiting the amount of power that can be transmitted into a hazardous area.
The iMAC EMM Module is an Intrinsically Safe Relay output module for the iMAC System. The iMAC EMM monitors the unique ‘Signal Line Healthy’ signal from the iMAC EOL (End of Line) Module to provide an alternative control relay (CR) output for the iMAC System.
The iMAC GRM Module is an Intrinsically Safe General Relay output module for the iMAC System. The module responds to iMAC Address 0 data and can be configured to operate off any bit (0-7) via a rotary switch located under the front fascia. There are three GRM variants to suit 24VDC, 110VAC, or 240VAC power supplies.
The iMAC CRM Module is an Intrinsically Safe Control Relay output module for the iMAC System. The iMAC CRM provides remote mirroring of the iMAC Controller’s Control Relay (CR). There are three CRM variants to suit 24VDC, 110VAC, or 240VAC power supplies.
The iMAC ARM Module is an Intrinsically Safe Auxiliary Relay output module for the iMAC System. The iMAC ARM provides remote mirroring of the iMAC Controller’s Auxiliary Relay (AR). There are three ARM variants to suit 24VDC, 110VAC, or 240VAC power supplies.
The iMAC RTD1 Module is an Intrinsically Safe temperature input module. The RTD1 provides a single channel RTD PT100 sensor input for monitoring temperature. The Module is powered directly from the iMAC L1 Fieldbus communication line.
