Flexible, modular components designed to fit your evolving building's needs

EasyIO Neo Series provides a modern, modular approach to building automation control systems, combining compact I/O, flexible networking, and intelligent edge performance. Designed for fast installation and expansion, it supports scalable BAS and BMS control system deployments across new and existing buildings.

By pairing high‑density, plug‑and‑play I/O with next‑generation edge controllers, the Neo Series reduces panel footprint, speeds up commissioning, and creates a future‑ready foundation for evolving building energy management systems (BEMS).

Features

  • Modular I/O architecture with up to 10 signal modules (80 points)
  • BACnet MS/TP and Modbus RTU compatibility
  • Spring (tool‑free) terminals
  • 16‑bit ADC with high‑accuracy measurement
  • Ultra‑thin, compact module design
  • Universal signal support for HVAC and lighting
  • Temperature‑compensated measurement (0°C to 50°C)
