DGH D7710 Ethernet MODBUS TCP/IP Digital Input Module

The D7710 15-channel digital input module is part of the DGH’s D7000 data acquisition module family-supporting RJ-45 Ethernet interface and communication via MODBUS TCP/IP protocol. This input module monitors ON/OFF signal inputs such as logic levels, contact closures and others. Each input contains its own pull-up biasing resistor and operates independently from each other, the data can be retrieved from the host computer using MODBUS RTU protocol. The D7710 output module can be directly connected to a wide range of sensors and annunciators. The D7710 module also features peer-to-peer (P2P) mode, sending the signal directly to a digital output module without the need to involve a host computer. It is also able to upload information to the cloud using ThingSpeak platform, and send e-mail notifications via Gmail free e-mail service (a limit value can be set for each channel separately, triggering the notification e-mail). For extra security, it utilises a non-volatile EEPROM (Electrically Erasable Programmable Read-Only Memory) to store all user-selectable settings such as the range, meaning the values are maintained in the event of power loss. The D7710 module is compatible with any commercial software supporting Modbus TCP/IP ethernet protocol and is DIN-rail mountable (MK-1 mounting kit required). Combined with other D7000 modules, it provides the complete, customised data acquisition system for a given application.
