The FreeWave IOEX‑4440 is an advanced I/O expansion module designed for industrial and remote‑automation systems. It adds up to 12 additional I/O channels. These include 4 universal, 4 input‑only, and 4 isolated digital input channels. These expansions occur when stacked with a FreeWave serial or radio base. Certified for Class I Division 2 hazardous locations and built for rugged environments, it is tailored for SCADA, telemetry, IIoT, and wireless I/O configurations.
Key features include:
- Adds 12 I/O channels for legacy or new systems (4 universal, 4 input, 4 isolated DI)
- Modular stacking: up to 15 expansion modules can plug into one base for up to 192 I/O points
- Certified for hazardous environments (Class I Div 2) and rated for –40 °C to +75 °C
- Supports analog inputs (4 ‑ 20 mA, 1‑5 V, 0‑10 V), digital I/O and sensor power for flexible deployment
Whether you’re expanding field telemetry, enabling wireless I/O networks, or scaling SCADA systems with modular I/O, the IOEX‑4440 delivers flexible, scalable and rugged I/O capabilities.
