Overview C2000 MD44 four digital inputs (DI) and 4 digital outputs (DO) collection equipment, DO can output normally open (NO), normally closed (NC) two states. Using standard Modbus RTU communication protocol for remote DI data acquisition and transmission via RS485 bus. This product has good scalability, easy to use. You can also convenient and flexible cascade flexibly through M244, M281, M2A8 and other capture devices with networking capabilities of low cost Ethernet access, and achieve a variety of digital and analog combination expansion acquisition. 5-year warranty. Features: → 4 digital inputs; → 4 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; → supply with Good overcurrent and overvoltage, against reverse polarity protection; → rich indicators and comprehensive view of the state, timely troubleshooting; → easy to install.
