7221 8 channel Measurement Processor (no scanner expansion) Measurement Systems

7221 8 channel Measurement Processor (no scanner expansion)

£925.00

The 7200 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 7221 Measurement processor includes 8 integral Analog Input Channels, individually configurable for Voltage, 4-20mA Current, Thermocouple, Strain ,PRT and Resistance measurement.

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.
