The instrument has three keys on the front panel, with which the operator can set the parameters and configure the instrument as desired. A four-digit red LED digital display is provided on the front panel which indicates the process value in real time. The display can indicate any scale range between –999 to +9999 units. A Micro-SD Card slot is available to insert or removed SD Card.The instrument has non-volatile memory (i.e., in case of power failure, the set points and other settings are retained in memory and the indication and control actions resume after power is restored).

The instrument accepts a standard analog current loop signal of 4 to 20 mA DC and displays the process value with Periodic data logging into Micro SD Card as well as in Microcontroller memory(Limited to 4000 logs), the set-points of which may be configured through the Membrane Keypad on the front panel. Data Logging will always start when process value crosses this set point.The process display is factory calibrated to the desired operating range of the input through the instrument software and may be changed whenever desired. The input signal is suitably isolated and conditioned by the micro-controller, which displays the actual process value in real time on the digital display.

The micro-controller based process Indicating and data logger Model VZ-70 is therefore an ideal instrument for process measurement applications because of it’s versatility and inherent accuracy in process measurement, besides other superior characteristics such as total immunity to shocks, dust, ambient temperatures, and humidity. It is available in standard DIN Rail enclosures. It operates on 24 V DC power supply.
