Function: FF MIO

FF Modular I/O connects conventional field signals to FOUNDATION Fieldbus H1. It makes use of established reliable hardware and employs standard FF multi-function blocks. It supports NAMUR or switch type inputs as well as solenoid outputs, temperature signals or supply circuits for 2- or 4-wire transmitters, proportional valves and positioners. In contrast to dedicated digital input devices the FF Modular I/O combines analog and digital I/O in one device.

The modular approach enables a very compact solution, offering up to 40 digital, or 20 analog, or any combination of analog and digital inputs and outputs. The FF Modular I/O is installed locally near the instrumentation. The fieldbus cable serves as backbone. A selection of housing materials and accessories enables installation in Zone 2, Zone 22, Div. 2, or safe area.
