Up to 4 physical Inputs - 2x TERMINALS + 2x MiniDin

Multilogger M1322 inputs
Removable inputs allows connection of:
  • Sensors with woltage output (range 0-10 V; accuracy ±10 mV)
  • Sensors with current output (range 0-20 mA; accuracy ±20 µA)
  • Devices with two-state output (potential-less contact or voltage signal 0-30V); may be applied to input 3 and 4
  • Devices with pulse signal (potential-less contact or voltage signal 0-30V); may be applied to input 4
  • Temperature probes Pt1000 with built-in configuration memory (serie xxx/M)
  • Temperature/relative humidity probes with digital output - DigiS/M, DigiL/M, DIGIH/M
  • The probes are interchangeable without calibration to a specific device and regardless of the length of the cable. The length of the cable can be 1, 2, 5, 10, 15 meters

Evaluation of up to 16 variables

Multilogger - LCD detail
Up to 16 variables may be calculated from the four connected probes / sensors. This is the sum of the measured and calculated values. The calculated values can be a further expression of moisture – dew point temperature, absolute humidity, specific humidity, mixing ratio, specific enthalpy. It can be also the result of inter-channel conversions, e.g. the difference of two connected temperature probes.

The measured values are stored in the internal non-volatile memory. Memory capacity is up to 1 million values. Logging mode can be adjusted as non-cyclic, when logging stops after filling the memory, or cyclic, when after fulfilling the memory oldest stored values are overwritten by new ones.

Measured values are displayed on the screen with backlight option and the ability to change the size of display digits

Power supply

Multilogger - Power Supply
Multilogger - Power Supply

Multilogger can be powered by AC adapter or by rechargeable batteries with charging capability. Batteries are always a part of the device (you can also use standard alkaline AA batteries). Batteries power the device for several months.

While using the AC adapter, the batteries provide backup operations and provide recording and measurement during power failure. Thanks to the Ethernet output the device informs about the failure via e-mail message.

Alarm limits and alarm indication

Multilogger - Alarm limits

It is possible to set two independent alarm limits for each channel (i.e. measured or calculated value).

Alarm signalization can be acoustic (built-in beeper), optical, sending an e-mail alert or an alarm output. The alarm output is for connecting an external audio or visual alarm.

Communication interfaces

Multilogger - Alarm limits

Multilogger is always equipped with USB connector for communication, data analysis and also for charging of the rechargeable batteries.

Included Ethernet interface allows to:

  • send an e-mail when an alarm state starts or ends
  • use DATALINK: display current values or download values from memory to Comet Database in your PC. Software Comet Database contains many useful tools for data analysis - graphs, tables, statistics, etc.
  • simple wireless communication with Wi-Fi TP-LINK router
  • third-party applications to read the actual measured values using universal protocols SNMPv1 and XML
  • view current measured values using your web browser

Output ALARM OUT

Multilogger - Alarm limits and alarm indication
  • Output can be used for controling other devices when alarm is launched, such as external buzzer, telephone dialer etc.
  • Type of output - open collector transistor
  • Max. switching current - 100 mA
  • Max. voltage on output - 24 V
  • Auxiliary voltage at terminal - +5 V (only when the mains supply is present)
  • Users can receive alarms if the values go outside the paramters set. Alarms are indicated through an internal buzzer , 3 LEDs or email alerts via Ethernet port.
