S7841 - Four Channel Event Logger
Event Logger S7841
It is possible to download recorded values to the PC by a communication adapter.
Applications:
- record of door opening / closing
- monitoring of functions of a machine
- record of technological processes
- record of running hours
Event logger advantages:
- variability of PC connectivity - RS232, USB, Ethernet, GSM modem
- permanent connection to the PC enabled, data is possible to download even during logging
- large data memory 32000 values
- large dual line display, switchable
- robust case
- easy installation, locking enabled
- low power consumption from battery, battery life up to 4 years
- indication of remaining battery life, easy replacement of the battery
- logging start/stop is enabled in several ways: at certain time and date programmed from computer, by delivered magnet or depending on logical state on channel 4 input
- each logical state is possible to describe from the PC. Description is used on the list of the recorded values
- 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

Data logger accessories
Battery is included in delivery. No other accessory is included. For basic use it is necessary to order at minimum a COM adapter or USB adapter or LAN 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.
Anytime it is possible to download free basic Windows program for data logger. Program enables to control all logger functions and viewing and printing of record in numerical and simple graphic format. It is possible to export recorded values to dbf or txt formats for further analysis.
