Data acquisition system MS55D
NEW - data logger MS55D replaces data loggers MS5D, MS5.
The reason of replacement is to offer system to user, which works from the user point identically as MS6 system, but it is equipped with input modules known from MS5 data loggers.
MS55D data loggers support all advantages of MS6 data loggers including faster communication protocol.
MS55D is designed to applications, where universal inputs of MS6 do not offer required parameters.
The complete solution for monitoring of temperature, humidity and other values especially
in following applications:
- Food and beverages industry (HACCP)
- Pharmaceutical industry (GMP)
- Blood stations, pharmacies
- Horticulture and cultivation of plants
- HVAC (heating, ventilation, air conditioning, cooling
- Building and energy management
- Building automation
- Research and development
- Laboratories (GLP)
Single-channel to sixteen-channel data loggers are designed for recording of values from transducers of variety of quantities, alarm state indication, and process control. Data logger with transducers configured accordingly to client order can measure analog signals, frequency, count impulses, evaluate two-state quantities and read data from devices compatible with Modbus RTU and ADAM Advantech protocol. Input signals are connected to removable terminal block located on the logger upper side. Analyzing of the record is enabled after data download to the personal computer by means of the included program via USB, RS232, Ethernet or GSM modem. Local or remote online data presentation is also enabled.
Free program for monitoring system for Windows is ready to download.

Data acquisition system especially enables:
- online data acquisition by means of the Ethernet interface. Communication via: SNMP, SOAP, internet www pages
- to get information from data logger by means of the SMS messages - actual values, alarms, memory occupation and others - as response to SMS request from the user and after alarm creation at the logger. Data logger should be connected via GSM modem supporting SMS.
- to configure individually each input channel for measurement, alarm evaluation and data logging, including individual data logging interval for each input.
- each input channel can be individually programmed for different modes of record (continuous record, time dependent record, record only if specified logic conditions are matched, record triggered by external signal, etc.).
- to set up to four different logic conditions for each channel to active alarm. Each condition compares measured values from inputs with set limits. It is possible to set hysteresis and delay of condition validity.
- to assign to each input channel name of actual recorded process to identify monitored object (e.g. type of monitored product). It is enabled to select this name from data logger keyboard during the operation.
- to indicate alarm state after matching defined combination up to four alarms from any inputs.
- Input signals are connected by means of the removeable terminal connector. Each input channel has three terminals - including shielding.
