LOGIC MODULES
x 20, total number of any combination of ‘NOT’,
‘AND’ and ‘XOR’ Gates
‘NOT’ Modules
This module requires no setting and is used to reverse the digital
inputs i.e. On/Off inputs. This can be any On or Off signal within the
IAC. For example, if a digital signal is Off when it goes into the inverter
it will be transmitted out as On and vice versa. In conjunction with the
"AND" gates, and ‘XOR’ Gates these inverters can perform interlock
functions.
‘AND’ Gate Modules
This module is used to take 2 digital inputs and "AND" them together to
give a new digital output. The gate must have both digital signals as
On before it will give an On output. In conjunction with the ‘NOT’ gates
and ‘XOR’ gates these gates can perform interlock functions.
XOR (EXCLUSIVE OR) Gates
XOR GATE, one input only must be On to give an On out. E.g. Off, On
= On out
NOTE:- All digital inputs work as a normal OR Gate within normal
modules when multiple digital signals are applied to a single digital
input. That is any number of the inputs are On then the output is On.
E.g. Off, On, Off, On, On in = On out
By placing a NOT Gate after an AND Gate the output is inverted thus
providing a NAND gate equivalent. A ‘NOR’ gate is created by
connecting two or more inputs into a ‘NOT’ gate. By placing a NOT
Gate after an XOR Gate an EQUIV Gate is created (if both inputs are
the same then the output is on if not the output is OFF).
LATCH MODULES
x 8
The Latch module is used to take a momentary Digital input and give a
latched output. The output will now stay on until it is cleared by the
reset input being set momentarily to on.
This module is used to monitor a pulse type signal and create a longer
signal.
DELAY MODULES
x 8
The Delay module enables an incoming digital signal to be
manipulated. By delaying the on state you can ensure that the
incoming signal must be on for a minimum amount of time before it is
recognised. By delaying the off state of the incoming signal a
minimum on time can be guaranteed. The output from the module can
then be used as an output to another module.

Delay Type = Hold Off
Edge = Rising
Re-trigger = No
Example 2: Minimum Run Time:
Period = T
Delay Type = Hold On
Edge = Rising
Re-trigger = No
Example 3: Minimum Off Time:
Period = T
Delay Type = Hold Off
Edge = Falling
Re-trigger = No
