WTRODUCTION 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). 2. NOTES ON SELECTING THE I/O UNITS 2.
