1. Introduction
Mains operated UNICOM 300 with mains supply is available in three versions:
•
The UNICOM 300 version with 2G/4G modem / datalogger
•
The UNICOM 300 version with 2G/4G modem / datalogger and backup battery for preservation
of the log functions.
•
The UNICOM300 version with 2G/4G modem / data logger and rechargeable accu for full
functionality.
Mains operated UNICOM 300 is a (GSM-CSD/GPRS/LTE cat.1) 2G/4G modem and data logger. The
inputs are equipped with Ex barriers so that mains operated UNICOM 300 may be used with equipment
that is placed in a zone 0 with a potentially explosive atmosphere.
Two microprocessors provide several functions including pulse registration, readout of an encoder
counter, processing and storage of data (data logging), communication of this data via 2G/4G, timer
(scheduler) for switching the 2G/4G modem on and off and creating and sending logged data in an FTP
message.
Mains operated UNICOM 300 is equipped with inputs for both Encoder and two pulse contacts and a
serial connection for communication with UNIGAS 300.
Mains operated UNICOM 300 can communicate in the following ways:
•
through GSM data (CSD)
•
through a TCP connection over GPRS/LTE Cat. 1
•
by sending FTP files. One FTP server can be set up where the FTP files are to be sent to.
•
synchronizing clock (date / time) with an NTP server
UNICOM 300 automatically detects the presence of a backup battery or a back-up accu and will adjust
a number of relevant functions itself.
