7321 8 channel Measurement Processor (w/scanner exp.port) Measurement Systems

7321 8 channel Measurement Processor (w/scanner exp.port)

£1125.00

The 7300 series is designed to provide a simple reliable accurate and cost effective means of connecting plant sensors to standard computers for real time monitoring and data acquisition.

The 7321 Measurement processor includes 8 integral Analog Input Channels, individually configurable for Voltage, 4-20mA Current, Strain, PRT / RTD and Thermocouple measurement.

The Local expansion bus offers the ability to connect with Datascan 7020 / 7021 / 7027 / 7031 / 7035 / 7036 / 7050 scanner expansion modules.

Alternatively, by using the units RS485 network port it can become part of a distributed network of up to 1000 channels spanning a distance of up to 1.2 Km.
