Overview C2000 MD82 to 8 digital inputs (DI) and 2 digital outputs (DO) acquisition and control equipment, DO can output normally open (NO), normally closed (NC) two states. Using standard Modbus RTU communication protocol for remote data acquisition and control transmission via RS485 bus. This product has good scalability, with M244, M281, M2A8 and other capture devices with networking capabilities through convenient and flexible Ethernet access to low-cost expansion cascade. 5-year warranty. Features → 8 digital inputs; → 2 digital outputs; → I / O and system completely isolated; → use Modbus RTU communication protocol; → RS485 communication interface provides optical isolation and 600W per line surge protection; → power supply has a good The overcurrent and overvoltage, against reverse polarity protection; → wealth of light. Comprehensive view of the state, timely troubleshooting; → easy to install.
