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.
The iMAC DO4 module is an Intrinsically Safe (Ex ia I Ma) Digital Output module that provides four (4) general purpose relay outputs.
The relay outputs can be operated directly from the iMAC controller or by programming an input module such as a DI4 module to the same address as the DO4 module, in which case each relay output will respond to the respective input of the DI4 input module. Multiple DO4 modules can be programmed to the same address, allowing distributed simultaneous control in multiple locations.
The Electrochemical (EC) CO and O2 models of the GG2 Detector are intrinsically safe sensors for monitoring the atmospheric concentration of Carbon Monoxide (CO) or Oxygen (O2) gas. The stainless steel housing is robust, corrosion resistant and fit for purpose. Power and communications is facilitated through the low profile connector, allowing for quick plug and play connections to compatible models, such as the GG2 Display.
The Ampcontrol Outlet Test System – Earth Leakage (OTS-EL) provides a fully automated outlet EL testing facility. The OTS completely eliminates paper-based record keeping by concurrently updating a historical database with the latest test data.
The OTS-EL is comprised of an OTS-EL module, embedded within the outlet electrics, and an OTS Comms Module, mounted on the door to provide Bluetooth connectivity to the outlet tester.
The OTS-EL System can be installed into Ampcontrol Substations, Distribution Boards and Outlet Control Boxes. The OTS-EL greatly simplifies the statutory testing process, performing a hands free, automated testing function whilst simultaneously providing a comprehensive record management tool.
