Two analogue channels and up to 8 digital ports are available at each remote unit. Communication is via either the national GSM radio network or a land line to the remote site with the host computer connected by a modem and dial up link to the Public Switched Telephone Network.
The remote analogue ports operate on a 4 to 20 mA current loop and can work with a range of sensors. Alternatively the sensors may be powered by the Remote Telemetry Unit - Series BI-5000 using the internal power supplies.
The analogue ports are fully isolated to operate on separately powered loops without any interference. Interrogation schedules may be pre-programmed in the host computer for a number of remote sites.
The analogue values read at each site are stored in a database at the host PC and may be printed directly in a series of reports or exported to other data processing applications for further analysis.
The system is ideally suited to interfacing with the Bintech BI-2000 and 3000 series liquid level measuring system. Optional 3½ digit displays may be fitted within the remote units for a local indication of tank level.
The digital output ports enable alarms to be reset, security systems controlled, pumps started or stopped etc. The standard software enables multi-site operation with a custom interrogation schedule for each site.
