INTECH Micro
2300-A8II
8 Channel mA Input Station
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 MicroScan 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 used
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.

- Page 3 2300-NET : Isolated Ethernet to RS485. 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.
- Page 4 2300-A8II Dimensions. The 2300-A8II enclosure is shown below. The station clips directly onto an industry standard DIN rail. Field wiring is on the top of the station via a separate plug in connector. The station power and RS485 communications wiring are on a separate plug in connector on the side of the housing.

If using the USB485 converter, do not connect to the computer until after MicroScan has been installed. MODBUS Applications: If using the 2300-A8II station in other applications where MODBUS is required, please refer to the 2300-A8II MODBUS supplementary manual which is available for download from the Intech website: www.intech.co.nz/2300... - Page 8 Do not mount in cabinets with power control equipment. To maintain compliance with the EMC Directives the 2300-A8II is to be mounted in a fully enclosed steel fire cabinet. The cabinet must be properly earthed, with appropriate input / output entry points and cabling.
