Monitoring and Operation
Monitors resistance of PTC resistors connected to terminals T1 and T2 (or 5 and 6)
Operates based on resistance thresholds related to motor coil temperature
Relay remains active when resistance is below rated value; releases when resistance exceeds the threshold
Includes a test button for fault simulation and manual reset
Alarm status indicated by red LED
Operation modes vary between models, with some relays providing remote alarm reset and others featuring internal reset buttons
Dimensions & Wiring
Detailed wiring diagrams and dimensions are available in the datasheet. The relays are designed for easy DIN-rail mounting or plug-in installation, ensuring flexible integration into industrial control systems.
Unfortunately I havent tested the 5G, Only difficult part was connecting antennas. But everything is good, by default it runs on Qualcom's QMI mode, Had to switch to MBIM and it works good with Windows. Planning to run with OpenWRT soon.
