S7021 - data logger with counting and binary inputs

Data logger S7021

Data logger is designed for counting of pulses, optionally for logging of time events from binary signal. Counter reading and actual state of binary input are displayed on dual line LCD display. Counter status is stored in adjustable time interval into logger´s non-volatile memory. Time of event (change of binary input state) is stored immediately after event. Data transfer to the personal computer for further analysis is performed via USB, RS232 or Ethernet interface by means of a proper adapter.

Main applications:

Advantages:

  • counter reading is possible to display in real value, range of the LCD display is 19999, after exceeding of displayable value only lowest places are displayed
  • two modes are enabled: after counting of maximum value counter stops or overflows and counts again, counter reset enabled from the PC
  • in the record is possible to indicate counter state or counter state increment between logging intervals
  • record from binary input contains date and time (resolution of 1 s) when change of input logic level appeared and its logic state
  • record from binary input can be disabled
  • it is possible from the PC to assign both logic states of binary input a description, which is displayed on the record – on the LCD logic states are always displayed as ON ( contact closed) and OFF (contact opened)
  • permanent connection to the PC enabled, data is possible to download even during logging
  • dual level alarm is enabled for counting input, alarm is indicated by blinking of the value on the LCD display
  • low power consumption from battery, easy replacement of the battery
  • logging start/stop is enabled: at certain time and date programmed from computer, by external signal connected to binary input or by delivered magnet
  • also special logging mode is enabled, when logging runs only, if counter value is out of adjusted alarm limits
  • input pulse signal is recalculated and displayed in real measured physical units by means of the PC software
  • extremely low consumption from the battery, indication of remaining battery life, easy battery replacement
  • robust watertight case, easy installation, locking enabled
  • each logger is possible to describe with text of maximum 32 characters
  • each channel is possible to describe with text of maximum 16 characters
  • password protection is enabled to prevent unauthorized manipulation with logger

Accessories

Data loggers are delivered without accessories. For basic use it is necessary to order at minimum a COM adapter or USB adapter for communication with computer, optionally a start/stop magnet, if needed to control logging the other way than directly from computer or by external binary signal. Also connector for input signals connection is necessary to order.

Anytime it is possible to download free basic program for Windows. Program enables to control all logger functions and viewing and printing of record in numerical and simple graphic format. It is possible to export logged values to dbf or txt formats for further analysis.

OPTIONAL ACCESSORIES
SWR001 optional software for Windows - color printing, vertical and horizontal zooming of graphs and other functions.
