The TA4621 model is a compact Ethernet sensor designed for precise temperature measurement using two external Pt1000 probes.

This type offers two independent inputs with an optimized measuring range of -200 °C to +260 °C and an accuracy of ±0.2 °C. Probe connections are realized via practical CINCH connectors, allowing one device to monitor temperature differences or two separate locations simultaneously.

The device features a backlit LCD display, complete alarm signaling (LED and acoustic), and PoE support. Significant features include inter-channel calculations and software compensation for probe cable error.

This makes the TA4621 ideal for demanding industrial processes, monitoring two freezers at once, or installation into superior systems.

Main Benefits:

  • 2× Pt1000 input for simultaneous precise temperature measurement
  • Ability to monitor temperature differences
  • Extreme temperature measuring range from -200 °C
  • Backlit LCD display, acoustic and LED alarm signaling
  • Power supply 5–24 V or PoE
  • Integrated backup memory
  • Modern web interface, IPv4/IPv6 support, Modbus TCP, COMET Cloud, and fully encrypted communication (HTTPS, SNMPv3, TLS)
  • Integrated detachable bracket for easy installation

Premium Ethernet Sensors with Display and Local Signaling

The TAx6xx series represents a new generation of Web Sensor 2.0 premium sensors. They combine precise measurement, modern network communication, and local monitoring via an LCD display, LED signaling, and an acoustic alarm.

Ideal solution for:

  • server rooms and data centers
  • laboratories and healthcare
  • industrial facilities
  • offices, schools, and public buildings
  • cleanrooms

Why choose TAx6xx?

Local monitoring without a PC

  • Backlit segmented LCD display (4 brightness levels)
  • Display of values, alarms, and IP address
  • Three-color LED signaling (green / yellow / red)
  • Acoustic alarm with local and remote mute options

Advanced next-generation alarms

  • 2 adjustable alarms per channel (no direction limits)
  • System alarms (measurement, time, or configuration error…)
  • Signaling via: LED, acoustics, e-mail (TLS / STARTTLS), Syslog

Calculations and advanced analytics

  • Dew point
  • Absolute humidity
  • Specific humidity
  • Mixing ratio
  • Enthalpy
  • Humidex and Heat Index
  • Inter-channel calculations (e.g., temperature difference, CO₂ difference)

Maximum connectivity and security

  • HTTP / HTTPS (custom certificate upload)
  • SNMP v1 / v2c / v3 (SHA, AES128)
  • Modbus TCP (including alarm mute and limit changes)
  • IPv4 + IPv6
  • COMET Cloud / COMET Database
  • TLS communication
  • 4 user accounts, 3 permission levels
  • Firmware updates via web

Power without compromises

  • 5–24 V DC
  • PoE (IEEE 802.3af)
  • RTC with battery backup
  • Backed-up memory (>2600 records)

Typical applications

Data centers

  • Monitoring of temperature, humidity, and CO₂ with instant LED indication.
  • Laboratories: High-precision Pt1000 inputs, cable compensation, alarms.
  • Schools and offices: CO₂ air quality "traffic light" for ventilation control.
  • Industry: Durable solution with PoE and SCADA integration.

The new platform brings:

  • new compact design
  • removable bracket for easy mounting
  • unified firmware
  • enhanced cybersecurity
  • RTC with battery
  • advanced alarm system
