T8151B module (GPRS wireless module, GPRS remote monitoring module) is a data communication product based on GPRS network, mostly installed in monitoring sub-station to realize remote data communication between sub-station field equipment and monitoring center. Features:
Communication function: support GPRS and SMS dual-channel data transmission; support data communication with multiple centers.
Acquisition Function: Acquisition of data from serial devices, such as serial meters, collectors, PLCs, etc.
Remote management function: support remote parameter setting and program upgrading.

T8151B modules can be installed in a standardized way and operate safely and reliably in harsh working environments where water, dust and vibration may occur. These features make them suitable for a wide range of applications, such as material handling systems, automated assembly systems, etc. Other features include support for PNP and NPN signal inputs, and embedded bright LED diagnostics to help maintenance personnel more easily determine the status of I/O, modules and networks.

The T8151B uses a high-grade rs-485 chip with complete protection measures such as electrostatic protection, overheating protection and input failure protection. Use faster response speed, withstand transient power greater new protection device tvs or bl surge absorber, such as p6ke6.8ca clamping voltage of 6.8v, withstand transient power of 500w, bl device can resist more than 4000a high current impact. If you use the chip without fault protection, such as sn75176, you can make some processing in the software, so as to avoid communication anomalies.
