Basic Description: This system is used for multi-point data accumulation e.g. if there are multiple points where temperature & Humidity (or any two analog parameters) are to be monitored and recorded locally. The alarms will be generated locally. Such multiple instruments will be interfaced to a PC through a centralized receiver.
Specifications:
Input – Analog 1: PT100 / PT1000 / 4 – 20 mAmp / 0 – 5 VDC
Input – Analog 2: PT100 / PT1000 / 4 – 20 mAmp / 0 – 5 VDC
(For Both inputs the type is Factory Selectable)
Excitation Voltage: Excitation Voltage for sensors is generated through the data logger keeping the sensor alive on the internal battery in case of main power failure.
