7220 16 channel measurement processor
No longer available. For information purposes only.
Description
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 7220 Measurement processor includes 16 integral Analog Input Channels, individually configurable for Voltage, 4-20mA Current, and Thermocouple 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.
Features
- Direct Sensor connection for DC voltages, thermocouples, and 4-20mA converters
- Integral network interface for distribution over 1.2 Km (4Km with extension unit)
- 16-bit measurement performance with 0.625µV sensitivity
- Solid State differential Inputs
- On board energisation
- In-built Cold Junction Compensation
- Serial Port isolated to 500 Vdc
- Local measurement speed up to 400 readings/sec, 1000/sec over the network
