TGRF-4744, Tinytag Plus Radio Logger with 4 Voltage Inputs, 0-25VDC
TGRF-4744, 4-Channel Radio Logger for Low Voltage, 0-25VDCThe TGRF-4744 monitors four voltages from 0 to 25VDC and can be connected to a variety of sensors enabling the logging of a wide range of processes.
The data logger is waterproof and suitable for outdoor, industrial and warehousing applications.
For custom sensor monitoring, including:
- Flow rate
- Power (with a current clamp)
If required the unit can also be powered by an optional mains power supply.
The unit is able to transmit logged data to another logger or a receiver and to store data locally in the event of radio contact being temporarily lost.
The data logger has got a status LED:
+ LED off: logger is off
+ green every 4 sec.: everything is o. k.
+ red every 4 sec.: not meshed or battery low or alarm indication
Please note: This article is only one component of the Tinytag Radio Logger System.
For proper operation minimum one radio data logger and one Tinytag radio receiver with accompanying software are necessary!
