ACKCIO DIGITAL NODE

CODE : N620
  • The Ackcio BEAM-DG Digital Node is a wireless data acquisition module designed for digital sensors operating via RS232, RS485, or SDI-12 communication protocols, enabling fully automated monitoring in geotechnical, structural, and environmental applications.
  • It forms part of Ackcio’s advanced wireless mesh ecosystem, allowing direct digital communication between field sensors and the central monitoring gateway without manual intervention or cabling complexity.
  • The BEAM-DG supports MODBUS RTU, SDI-12, and custom serial communication protocols, providing exceptional versatility and compatibility with a wide range of third-party instruments and data loggers.
  • The node supports baud rates between 4800 and 115200, with multiple digital ports (RS232, RS485, and SDI-12) allowing flexible integration of various sensor types including ShapeArrays, in-place inclinometers, tiltmeters, and smart digital sensors.
  • Designed for reliability in harsh environments, the BEAM-DG features a rugged die-cast aluminium enclosure with IP67 protection and an operating temperature range of −40 °C to +80 °C.
  • Power can be supplied internally by high-capacity Li-SOCl₂ batteries or externally from a 12 V DC source, ensuring long-term autonomous operation.
  • Wireless communication is handled by Ackcio Mesh, a low-power, self-healing network providing secure (AES-128 encrypted) and long-range connectivity up to 5 km in line-of-sight conditions.
  • Configuration and diagnostics are managed through the Ackcio Nimbus Android application, enabling rapid deployment and simplified network maintenance.
  • The system includes comprehensive surge, short-circuit, and reverse-supply protection to ensure stable field performance and long-term reliability.
  • Mounting options include a durable multi-purpose bracket that supports both vertical and horizontal installations on structural surfaces or poles.
