Type
Description
Function
Example Application
LED4
4 x LED Output
Module
Provides 4 x Output LEDs
that mimic the state of an
input module with the
same address.
Alternatively, LEDs can be
remotely controlled by the
iMAC2 Controller.
Control LED outputs at remote locations
e.g. indicate remote isolation, status of
conveyor signal lines etc.
Can be used in hazardous areas.
LIM
LED Indication
Module
Provides 7 selectable LED
profiles for green, yellow
or red flash sequences.
Responding to a 4-20mA Analogue Input
with green, yellow or red LED indication.
Serial Interface Modules
The iMAC System allows certain external equipment to communicate with the iMAC2 Controller through the
use of Serial Interface Modules. These modules form a communication bridge between the iMAC System
and compatible RS485 Modbus devices, allowing up to 16 Modbus Holding Registers to be read from a
Modbus Slave RTU device and be transmitted to an iMAC2 Controller across the iMAC Fieldbus.
