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.
High quality conveyor E/stop pull wire supports for utilisation on overland bulk material conveyors and underground slack line conveyors.
The Ampcontrol iMAC Conveyor Pull Cord system has been specifically designed to meet the challenge of maximizing production whilst maintaining safety in harsh, hazardous industrial environments.
The Ampcontrol Pull Wire Supports are high quality E/Stop lanyard supports intended for use in overland bulk material conveyors and underground hard rock/coal mine conveyors. The Pull Wire supports are constructed from a flame retardant polymer compound, providing superior impact strength, rigidity and UV stability. The material is non-corrosive and low friction and complies with IECEx 60079.0:2012 anti-static requirements.
This document is intended to provide a detailed explanation of the communications protocols supported by the iMAC2 Controller’s Ethernet port. The iMAC2 Controller uses industry standard Modbus TCP/IP protocol for exchanging data with compatible Ethernet devices. The iMAC2 Controller facilitates a Modbus Slave (server) device. This document is not intended to provide information on the operation of the overall iMAC System, individual modules or instruction on programming the iMAC2 Controller or modules. Please refer the relevant supplementary documents for this information.
In May 2018, the iMAC / iMAC2 Controller operating system firmware was modified to extend the iMAC Module Serial Number range. These changes occurred in iMAC Controller Operating System Firmware v4.0 (O.S. v4.0). Marcus Punch Pty Ltd was engaged to perform a safety integrity verification of these changes. iMAC2 report AMP-15-01-A1 Revision 3 (including Revisions 4 & 5) and iMAC report AMP-11-05-A2 Revision 2 (including Revisions 3 & 4) assessed these changes to be in compliance with the requirements pertaining to software modification and as a result the existing safety metrics (PFD and PFH) for the iMAC Controller, iMAC2 Controller, 2-wire and 3-wire iMAC systems remain unchanged.
iMAC Modules typically need to be programmed (configured) when connected to the iMAC L1 Fieldbus communication line. The iMAC Controller is used to program the modules. Each module (data register) must be programmed with an address and up to three other parameters. The parameters are used to control how a particular module behaves.
The SLE Signal Line Relay is designed to control conveyors in industrial and mining applications. The SLE Signal Line Relay is normally installed in the conveyor starter panel. The signal line is connected between the + and – Terminals of the Relay. The – Terminal is internally connected to the Earth Terminal. It is important that control switches are only connected to the + Signal Line.
Meet the challenges of maintaining safety while maximising productivity on underground and overland conveyors with Ampcontrol’s iMAC conveyor safety and remote isolation systems. With Ex ia certification for Group 1 explosive atmospheres and the ability to monitor distributed I/O over distances of up to 10km on a single cable run, the iMAC Conveyor safety and remote isolation systems are suitable for use on both underground and overland conveyors.
