|Auxiliary Alarm I/O|
High performance - at low Cost through advanced technology with each measurement module having its own individual 17 bit integrating ADC giving 200 or 40 measurements per second with 1uV sensitivity and 0.6C accuracy
High Termination Density - designed for location locally to each site requiring measurement or control functions High quality cage clamp connections.Thermocouple modules have purpose built isothermal connections for improved accuracy.
Robust purpose moulded Case - In a Compact module size-20 channel-plus 4 auxiliary I/O's-measures 100mmH 180mmW 45mmD.Easily enclosed in instrumentation housings with other equipment,the modules are stackable and Din Rail.
RS485 multi drop network - operating at standard Baud Rates.There is a second RS232 interface on each module for local programming during installation.Up to 5 modules can be powered from the ISA 485 serial inteface
Fast Communication - to support up to 99 modules or 1980 channels per network over 1.2Km at up to 76.8K Baud.Ethernet communication is available as an alternative for data transfer using TCP/IP protocol on its own IP address
Simple, concise programming - per module of secure error checked protocol instructions for each of the individual modules,via host computer or local terminal, aids configuration and installation.Software drivers and subroutines are supplied for measurement types allowing the highest performance
Software Calibration - Local or Remote which requires no module access for calibration. On module EEPROM storage is used for all calibration and set up parameters.
Concurrent performance - Allowing simultaneous measuring, engineering conversion, alarm processing and communication for maximum performance of operation
Local Alarm - with acknowledge inputs are available on all modules and triggered by any channel outside the pre-progranmmed threshold limits. Individual parameters can be changed without interruption to operation.
Digital Modules - Control of plant signal timing functions, counting and frequency period measurement for events with LED indicators per channel and programmable filtering of channel groups and synchronisation between modules
Flexible power requirements - 24 VAC or 12 to 28VDC module supply with the input fully isolated from input connections and communication ports.
