7021 8 channel analog input module (V, I, Tc, PRT & Strain) Measurement Systems

7021 8 channel analog input module (V, I, Tc, PRT & Strain)

£650.00

The Datascan 7000 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 7021 Analog Input expansion module includes 8 integral 6-pole differential Input Channels, individually configurable for Voltage, 4-20mA Current, Thermocouple, Strain ,PRT and Resistance measurement.

It provides cost effective expansion for the Datascan Measurement Processors (7010, 7320,7321) with up to 16 of these modules being able to be added to a single Measurement Processor unit.
