The Avior ECO (2904.CL.NB) is a low-power DIN rail-mounted cellular controller for remote monitoring and control of industrial and building automation systems where energy budget matters — off-grid, solar-powered, and battery-backed sites. This version runs on a 9–27 VAC / 9–35 VDC wide-range power supply and includes built-in 2G/3G/4G cellular connectivity for primary connection. A factory-installed Li-Poly backup battery provides 15 minutes to 6 hours of operation during power loss. It combines 6 digital inputs, 4 analog inputs, and 4 relay outputs with an embedded web server, Modbus, MQTT, and HTTP support — enabling local and remote control without additional middleware. Alerts can be sent via SMS, call, email, chat, HTTP, or MQTT on any local event.
Unlike the standard Avior, the ECO has no WiFi or Bluetooth — it operates exclusively over cellular and supports Sleep (30 mW) and Hibernate (0.8 mW) low-power modes to dramatically extend battery life on energy-constrained deployments. Analog inputs accept 0–10 V, 0–20 mA, or NTC signals (±2% accuracy); relay outputs are rated 3 A / 250 VAC. The unit fits a 4-module DIN EN-50022 rail, is rated IP40, and operates from −20 °C to +60 °C.
Note: Built-in 4G LTE cellular connectivity (with UMTS/GSM fallback) requires a microSIM (3FF, 3 V / 1.8 V) — not included.
