DGH D8710 Digital Input USB Module

The D8710 15-channel digital input module is part of the DGH’s D8000 data acquisition module family with the USB interface. This input module is able to monitor logic levels, contact closures, switch closures or dry contacts, utilising an internal 10K pull-up resistor on each input terminal. The input terminals can accept signals between ±30Vdc without damage. The D8710 input module can be directly connected to relays and annunciators. 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 D8710 module connects to the host computer via USB interface and is compatible with any commercial software supporting Modbus RTU protocol and is DIN-rail mountable (MK-1 mounting kit required). Combined with other D8000 modules, it provides the complete, customised data acquisition system for given application.
