Technical Data Sheet – iMAC Digital Output Module D04

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.

User Manual – iMAC2 Controller Modbus TCP-IP Communications

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.

Declaration of Conformity – iMAC Controller

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.

User Manual – iMAC Module Programming Procedure

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.

Technical Datasheet – iMAC LIM

The iMAC LIM is an Intrinsically Safe (Ex ia), highly configurable remote indication module, which interfaces directly to the iMAC Fieldbus.

Catalogue – H3RO Harsh Environment Reticulated Optics

With fibre optics becoming the absolute foundation of all industrial networking and cabled communications infrastructure, we’ve made things easier with H3RO – Harsh Environment Reticulated Optics. By using a combination of 12 and 4 core optical cables and H3RO Bots, a relatively limitless number of industrial Ethernet application scenarios can be achieved with this simple modular system.
