Data archivation
To store the values of the measured parameters, the registering device is equipped with a built-in non-volatile memory of not less than 2 Mb. The memory operates as a cyclic one rewriting new data in the archive beginning when the memory is full. The frequency of data registration in the archive is 1-60 sec (set by the user). The time period for archive storage at the archive period of 3 second is at least 30 days. Archive file reading can be conducted through interfaces RS-232 or RS-485 on the computer and a USB-flash card through the interface USB-Host(only for the version 01).
Built-in power supply source
The calibrator consists of the built-in stabilized DC power source (the output voltage is 5; 12; 24 V) with the overload and short circuit protection device and galvanically separated from other circuits.

By the customer’s order the registering device version 01 is completed by the interface USB-Host to record archive data on the USB-flash card
There is an opportunity to connect the registering device with the interface RS-485 directly to a PC through the USB interface with the help of a converter of interfaces ЭнИ-402 (RS-485 USB)(see the catalogue section «Interface converters»). Recommendations on Layout of Main RS-485.
Commutation channels
Depending on its version, a registering device may have up to four galvanically separated commutation channels of AC and DC circuits, Commutation is ensured via a relay, optical relay or optical bidirectional triode thyristor.
The commutation channels state (closed/open) depends on the preset values (trigger level, hysteresis and trigger logic), the measured parameter value and regulation law. The preset values and parameters of a registering device by the customer. The registering device operation logic enables PID- control.
