Specialty Modules
In addition to the above module types, the iMAC System also has a speciality module for monitoring
conveyor belt speed, belt slip and belt sequencing. For detailed information on the installation and operation
of this module, refer to the relevant technical datasheet.
Type
Description
Function
Example Application
SSW
Speed Switch
Module
Monitors two proximity
sensor heads, one on the
conveyor drive roller and
one on the free running
idler roller.
Provides belt slip protection, speed
indication and sequence control for
conveyor belts using the iMAC System.
Protection Modules
The iMAC system has two lightning protection modules available. For detailed information on the installation
and operation of these modules, refer to the relevant technical datasheet.
Type
Description
Function
Example Application
LPU2
Lightning Protection
Module for 2-Wire
Modules
Provides lightning
protection for 2-wire iMAC
modules
Sacrificial lightning transient protection for
2-wire modules e.g. DI4 module.
LPU3
Lightning Protection
Module for 3-Wire
Modules
Provides lightning
protection for 3-wire iMAC
Modules.
Sacrificial lightning transient protection for
3-wire modules e.g. IIM module.
End-of-Line Modules
iMAC End-of-Line modules form a key part of the safety feature of the iMAC System. In order for the iMAC2
Controller Control Relay (CR) to be energised, the Controller must be successfully communicating with the
End-of-Line module.
There are two types of End-of-Line modules, the End-of-Line (EOL) module and the Monitoring-End-of-Line
(MEOL) module. In 2-Wire systems, only the EOL module is required, 3-Wire systems require both an EOL
and a MEOL to be installed and communication to be healthy before the Control Relay (CR) can be
energised.
Type
Description
Function
Example Application
EOL
End of Line
Module
Ensures healthy communications
on the L1 fieldbus signal line.
Required in all iMAC Systems where
the Control Relay (CR) safety function
is required. Terminates L1 fieldbus
signal line.
MEOL
Monitoring End of
Line Module
Ensures healthy communications
on the L1 fieldbus monitoring line.
Required in all 3-wire iMAC systems.
Terminates L1 fieldbus monitoring line.
