Z-GPRS3

2G data logger with integrated and expandable I/O, logic functions, remote control and alarm management

Z-GPRS3 is a datalogger that can meet the growing demands of data acquisition, analysis in real time and integration with IT systems existing in automation and system/process monitoring. In line with the new productivity and communication models of Industry 4.0 and Internet of Things, it is characterized by a GPRS modem, 4 integrated communication ports (1 Ethernet 10/100, 1 RS232/RS485, 1 RS485, 1 MicroUSB), 8 integrated I/O channels (4DI/meters/totalizers, 2AI, 2DO), voice alarms/audio controls with DTMF tones and the support of Ftp, Smtp, Smtps, http rest, https, ModBUS RTU, ModBUS TCP-IP and SMS communication protocols.

Z-GPRS3 offers maximum opening towards the outside and third parties (PLC, HMI) thanks to the technology standards it complies with such as ModBUS RTU Master/Slave, Master ModBUS TCP-IP Server/Client. This unit supports different types of SIM cards and has an 8MB Flash memory, a slot for microSD expandable up to 32GB and multi-tasking real-time operating system. Like all SENECA advanced dataloggers, Z-GPRS3 is fitted also with a built-in UPS that allows an operating autonomy of up to 1 hour in case of lack of primary power supply. This unit guarantees open and flexible programming, thanks to a dedicated environment for the development of control logics (SeAL), an integrated Web Server, a mobile app (iOS/Android) for the direct management of controls via SMS and a data import/display tool (Log Factory). Z-UMTS, Z-GPRS3 e Z-LOGGER3 can be integrated with Scada, Cloud, databases and third party’s web portals already available in the systems or at the final users. The combined use of these dataloggers with the Cloud-IoT solution proposed by SENECA (Cloud BOX) completes the possibility of data management through responsive webpages with customisable dashboards and widgets.
