The multi-input/output (IMO) from Pepperl+Fuchs is a multifunctional device for DIN rail installation and connects discrete inputs and outputs to fieldbus. It is typically installed in a field enclosure close to the sensors in the hazardous area, thereby minimizing wiring. The MIO is certified intrinsically safe and as associated apparatus: inputs and outputs are intrinsically safe even when the fieldbus connection is not.
The MIO device provides connections for up to 12 discrete inputs and 4 discrete outputs. The device is compatible to components FD0-VC-Ex* and FD0-BI-* and offers control and position feedback for 4 low-power valves. Measurements for breakaway time and runtime can be set with limits for alarming. Automatic partial stroke testing is configurable. 4 inputs can be configured for vibrating forks and 1 input for frequency and counter signals, e. g., for rotating equipment.
The MIO communicates data, configuration, alarms and function blocks to the distributed control system (DCS). Inputs can be configured all at once or individually. The fieldbus powers the sensors and the MIO itself, extra power or wiring are not required.
