When connecting to MicroScan V5 software
Overview
The Intech Micro 2300 series is a system of modular I/O Remote Stations, that add an even lower cost option to
Intech’s already extensive intelligent I/O Remote Station family, which connect automatically to the Intech
MicroScan V5 logging plus SCADA software package.
The 2300 series I/O stations are made up of stand-alone Digital and Analogue—Input/Output stations.
Communications between the computer running MicroS can V5 and the 2300 series stations is RS485
(1 pair cable) multi drop as standard with an option for TCP.
A 32bit ARM CPU is used in the 2300 series stations to provide high speed data processing and fast
communications turn around times. All 2300 series stations have been equipped with status led’s which are use d
to indicate the status of the Inputs or Outputs. This visual indication assists with fault finding and diagnostics.
All the I/O stations clip directly onto an industry standard DIN rail. All stations have a minimum isolation of
1000VAC rms between the field and logic.

Description.
The 2300-A8II remote station has 8 isolated current inputs. The inputs are fully isolated from input to logic and
between inputs. This station is ideal for monitoring existing 4~20mA current loops which are isolated from each
other and cannot be connected to a common point of reference.
Ordering Information.
2300-A8II 8 Isolated Current Inputs. RS485 COMMS, Modbus RTU. 24Vdc Power Supply.
Quality Assurance Programme.
The modern technology and strict procedures of the ISO9001 Quality Assurance Programme applied during
design, development, production and final inspection grant long term reliability of the instrument. This instrument
has been designed and built to comply with EMC and Safety Standards requirements.
CAUTION: Dangerous voltages may be present. The 2300-A8II has no user serviceable parts.
Protective enclosure only to be opened by qualified personnel.
Remove ALL power sources before removing protective cover.
1.1 Factory Configurations
The Intech Micro 2300 series I/O Remote Stations are factory configured to connect directly to MicroScan V5
software. Only the Station number (station ID) needs to be set via the easily accessible dip switches. No other
station settings are required, making the new 2300 series one of the most friendly available. Simply setup the
Station number on each 2300 station, install and the MicroScan software will scan the data hi-way and
automatically locate each station. All stations will be displayed on a visual map.
1.1.1 I/O Expansion
Expansion is made easy by simply installing another station with a unique station number and instructing
MicroScan to find a new station. MicroScan will support up to 127 stations. Although RS485 data hi-way is rated
for 1200 metres, it is recommended to use an RS485 booster every 500 metres or between each set of 16
stations. Due to the large variation in site conditions, this advice is based on typical site conditions and does not
guarantee no fault operating conditions.
