General Description
The LB-480 recorder is used for collecting and recording measurement data, subsequently shared via its communication interfaces (first and foremost: Ethernet) with the use of a range of various communication protocols.
Exemplary Applications
- Server room monitoring: temperature measurement in different points, air humidity measurement, flood sensor, door open sensor with sensor line sabotage detection.
- Mini weather station measuring the following: air temperature and humidity, atmospheric pressure, wind speed and direction, insolation.
- Local temperature measurement: possible to measure temperature in 8 points with simple and inexpensive direct thermistor probes.
- Multipoint temperature measurement: with 8 LB-711 sensors connected, temperature measurement is possible in 64 points; each probe features high accuracy measurement thanks to the platinum sensors connected with 4-wire leads.
Measurement inputs
The module is equipped with 8 inputs, each of which may be individually and independently configured to operate in the following modes:
- Any S300 sensor
- Thermistor thermometer, range of -50…+150°C
- Pt1000 thermometer, range of -200…+850°C
- Voltage measurement 0…10 V
- Current measurement 0…20 mA
- Analogue scaled input (measurement 0…10 V / 0…20 mA scaled to any other range with a measurement unit added)
- Pulse input — event counter
- Pulse scaled input (pulse counter with the possibility of defining the value of a single pulse and measurement unit)
- Binary input — positive
- Switch — detection of switch state with an anti-sabotage alarm in the form of line shorting/interruption
The module features a built-in internal temperature sensor.
Possible to connect additional measurement sensors with the use of extension modules.
Data Archiving
The module may record data in 2 ways:
- Internal memory storage (RAM).
The built-in storage capacity is 1 MB mainly designated for data recording. The memory storage features its own power supply from an integrated battery and keeps the content safe when the device is switched off. This memory may be accessed directly via LBX software.
- Memory card storage.
Concurrently with saving data to the built-in memory storage, the recorder may save data on a memory card. The data may be subsequently read on a computer. The memory card is not mandatory for recording data — the internal memory is always available. Its capacity, however, is quite limited, and a memory card enables data archiving throughout a much longer period of time.
Communication Interfaces
- Ethernet
This is the basic communication interface of the recorder, enabling connection to a data transmission network (or directly to a computer). It may operate in 10/100 Mbit/s modes.
An optional power supply through Ethernet — POE — is also possible. - USB
A USB interface enables communication between the module and LBX software installed on a computer.
- Bluetooth
With the use of an additional Bluetooth module, the LB-480 module may communicate with the LBX software installed on, for example, a portable tablet, without the need to integrate cable connections.
- RS-232, RS-485
Via these ports, the recorder may communicate with any other device, or operate as a MODBUS slave type device.
- GSM/GPRS
This module enables remote access via GSM/GPRS mobile network data transmission. An additional GSM module modem is required.
Communication Protocols
The module enables data reading via popular standard communication protocols:
Extension Modules
The functionality may be extended with additional modules. Any 3 modules may be installed at the same time:
- RS-232
- RS-485
- USB
- Bluetooth
- Relays
- GSM/GPRS modem
- GPS receiver
- Module of 3 additional S300 inputs (after the installation of 3 modules, 9 additional S300 inputs are provided)
- Fast/accurate A/C converter (ADC 24 bit @ 1 sps / 8 bit @ ~1000 sps)
- Precision Thermometer 0.001°C
Alarm Signalling
The module may operate alarm signalling independently. There are 32 independent alarms available, and each of them features an individual source (the size measured from any given sensor) and independent output. The following inputs are available:
- syslog — sending messages to remote log
- SNMP TRAP — sending notifications to SNMP agents
- email (SMTP) — sending electronic emails
- sound signalling
- digital positive output / relay — may switch on any executive device
- SMS — sent to a selected phone number
Software
The basic software for reading and visualising data is the LBX application.
Data from the recorder may also be loaded with the use of standard communication protocols, which enable integration with any other IT systems.
LB-480 Thermometer–Recorder Applications
The LB-480 recorder is designed for controlling and documenting climate conditions during the course of technological processes in production facilities, logistics warehouses — especially in pharmaceutical, medical and food industries. It is especially useful in meeting the requirements for ISO and HACCP production quality control. When equipped with suitable external sensors, e.g. LB-710T thermometers or LB-710A hytherographs, the recorder may be used to control temperature and humidity in rooms. The LB-480 recorder caters to the safety requirements for the storage of vaccines, medicines and other products sensitive to temperature in State Sanitary Inspection facilities, outpatient clinics, hospitals and pharmacies.
