¶ Device Description
Multi-channel ROSSMA IIOT-AMS ANALOG Ex X4 meter-switch for analog (current, resistive) signals with wireless data transmission over LPWAN networks (LoRaWAN, NB-IoT standards). This switch is equipped with four analog inputs.
WARNING: Meter-switches are equipped with non-rechargeable lithium thionyl chloride (LiSOCl₂) battery ER34615M/T manufactured by Fanso. Attempting to charge the battery may cause fire!
Explosion-proof modifications (Ex) have explosion protection marking 1Ex e IIC T4 Gb X and are designed for operation in hazardous areas according to GOST R 31610.0-2014. Protection rating IP66.
The meter-switch supports two operating modes:
¶ ✅ Operation with Active Instruments
Operation with instrumentation devices powered by external power supply.
¶ ✅ Operation with Passive Instruments
Operation with instrumentation devices powered by the built-in battery of the meter-switch.
