The I-87211W, a new GPS solution for GPS Receiver module of I-87K family in ICP DAS, featuring high sensitivity, low power consumption and ultra small form factor with DCON and GPS protocols. This powerful item provides you with superior sensitivity and outstanding performance even in the harshest environment. The I-87211W provides extra 2-channel DO and 1-channel PPS for users. PPS signals can be used for precise timekeeping and time measurement. One can combine the PPS functionality with another as time synchronization source.

Therefore, the I-87211W can be a powerful GPS module as well as a general purpose GPS module with RS232 interface in PACs and remote I/O expansion units. It can also be applied in automotive navigation, Personal positioning and navigation, Marine navigation, Satellite time correction and etc…
