The SCADALink IO900 is a Modular Point-to-Point I/O Telemetry System that allow license-free, bi-directional transmission of digital and analog process signals at distances of up to 20+ miles. The base IO900 Controller which has 1 AI, 1 AO, 2 DI, and 2 DO points. The IO900 System also uses a simple-to-use modular system that allows an addition of up to 8 I/O Expansion Modules to expand its I/O capabilities.
- License Free 900MHz
- 20+ Mile Range
- Secure Factory Set RF Configuration
- 12-30VDC Operation
- Class I Div II
- DIN Rail Mounted Modules
- For Point-to-Multipoint module, see SMX-900
- Modular Expansion to 8 I/O Modules
Bentek Systems' I/O Modules can be attached to the IO900 via the I/O bus:

The following figure shows two I/O expansion modules, the AI4 and the DO8, connected to the IO900:
