This manual describes handling instructions and specifications
for
the A2C I/O unit,remoteterminalblock
I/O unit andremote
connector I/O unit (to be referred to as MINI remote I/O in this
manual) to be used with the AZCCPU unit (to be referred to as
A2CCPU inthis manual).
The MINI remote I/O is a simple I/O unit of baseless building block
type which connects itselfto the A2CCPU with twisted pair cables
without a base unit. The maximum length of twisted pair cables
allowed for this connection
is 100 meters (3.28 f?).
The MINI remoteI/O can be mounted easily to the DIN rail usingan
optional DIN railadapter.
The MINIremote I/O can be used as the I/O moduleforthe
MELSECNET/MINI-S3data
link system (to be referred to as
MINK33link in this manual).

I
Since an A2C It0 unit, remote terminal block I/O unit or
remote connector unit is aremote I10 module for the
twisted pair data link, cable connection can be made only
withtwisted pair
cables.

(1) Triac .output- units should be used instead of relay contact
output units when:
0 The outpubs are being switchedveryfrequently.
0 A large inductive load isbeingswitched.
0 Aninductiveloadwith
a lowpower factorisbeing
switched.
The life ofa relay switching any of the above conditions will be
substantially reduced.
,
(2) The ON time and OFF time for any inductive load switched by
an output unit must be more than one second.
43). Bsware of rush-currents whena transistor output unitof which
.mximum Load current is 0.3 Ais used to switch a load
incorporating a DC/DC .converter (e.g. a timer or counter).
Either connect a resistive or inductive load in series with the
load or use an output unit of which maximum load current is
large.

an external fastblow'fuse should be used at each point where fuse protection
isrequired.
The following external fast-blow fuses are recommended.

The overcurrent protection device shuts off the 24V
DC circuit and stops the systemif the current flowing
in the circuit exceeds the specified value. When this
device is activated, thepowersupply
unit LED is
switched off. In this case, remove any cause of
overcurrent and start up the system.
"3: Overvoltageprotection
The overvoltage protection device shuts off the 24V
DC circuit and stops the system if 31.5 to 38.5V is
applied to the circuit. When this device is activated,
the power supply unit
LED is switchedoff. In this case,
switch off, then on the input power to restart the
system. Thepower supplyunit must bechanged if the
system is not booted and the
LED remains off.

there is 4mA leakage current.
The voltage VTBacross terminal and commonis obtained by the
followingexpression:
VTB= 4 [mA] X 3.3 [ k Q 1 = 13.2 [VI (Voltage drop in LED is
ignored.)
Since the voltage does not satisfy the
OFF voltage of 4V or
lower, the input signaldoes not turn OFF. Therefore, connect a
resistor as shownbelow.
