Multi-Channel IR Monitoring System RS485/Modbus Outputs

The OS-MINIHUB IR Monitoring System is an industrial infrared temperature monitoring system, with miniature sensing heads and optional display modules. OS-MINIHUB sensors are designed to measure the surface temperature of non-reflective materials in industrial applications, from -20 to 1000°C (-4 to 1832°F). They are sealed to NEMA 4 (IP65), built from 316 stainless steel, and fully tested to industrial EMC standards.

OS-MINIHUB sensors have an operating temperature rating of up to 120°C (248°F) with no need for cooling.


The sensors measure just 45 mm (1.7″”) long (plus cable gland), so they can fit into the smallest of spaces.


Up to 6 sensors can be connected to the optional TSD600 interface module, which provides temperature display, configuration, and high-capacity data logging to a MicroSD Card. Analog and relay outputs are available via separate DIN rail mounted modules.

Low Cost

With up to 6 sensors connected to one TSD600, the OS-MINIHUB is an ideal low-cost non-contact temperature measurement system.


To measure more than 6 locations, OS-MiniHUB sensors and TSD600 sub-networks may be connected to an RS485 Modbus SCADA system or PLC. It is possible to measure the temperature of hundreds or thousands of locations on the same network.
