- ARTU-KJ8 remote communication& control unit is designed particularly for acquisition of switching value and remote relay output in applications like intelligent distribution and industrial automation. It implements the data exchange through communication and upper computer monitoring system.
1 Product features
1) It is equipped with channel state indicator and communication state indicator.
2) It applies both software and hardware Watchdog in order to prevent the system halting.
3）Its size is small, and easy to install.
2 Working conditions
1)Auxiliary power supply: 24VDC（±10%）
220VAV,allow AC/DC AC/DC 85~265V
2)Power consumption: ≤5W
3)Working temperature: -5℃-+55℃
