Features
Ursalink 4G/LTE Remote I/O with RS232/485, digital Input and Relay
Ursalink UC3452 is designed as a cost-effective industrial machine monitoring device that monitors and controls up to 1 RS485, 1 RS232, 1 DC signal and 1 drivable relay output. With the aid of the Ursalink UC3452, the alarm condition brings attention to engineering personnel immediately. Also, with Ursalink Cloud, the engineering personnel can trigger any relay outputs from anywhere at any time. The device can give immediate response to the status of both input and output conditions. A cellular modem is embedded in the Ursalink UC3x52.
(Model Naming Rule: UC3252 = 2G network version, UC3352 = 3G network version, UC3452 = 4G network version, UC3552 = NB-IoT network version)
