Secure Discrete Signals, Maximum Functionality

FieldConnex MIO monitors the status of up to twelve NAMUR sensors or controls up to four valves—including final position feedback and partial stroke test. The Multi-Input Output is equipped with integrated breakaway and runtime monitoring for valves, and emits an alarm signal when limit values are exceeded. The MIO also enables overflow and idle level of containers and conduits monitored by vibration limit switches. For the first time, the fieldbus component collects signals from pulse and frequency generators. The MIO‘s features allow targeted and predictive maintenance and extended maintenance intervals with the highest level of efficiency. This prevents unplanned downtime and increases the economic efficiency of the plant.

All inputs and outputs of FieldConnex MIO are intrinsically safe and offer simple, convenient handling due to their ability to be configured collectively or individually. The component is installed in the immediate vicinity of the sensor to ensure efficient plant design. This reduces the wiring effort as well as the cost and time required for installation. In addition, the improved cable entrance and generous terminal space ensure simple connection.

The interchangeability of Multi-Input Output with existing FieldConnex products, like valve couplers (FD0-VC*) and binary inputs (FD0-BI*), is also guaranteed. To do this, the MIO identifies itself as the configured product at the request of the control system. Module exchange is possible during operation, since the control system configuration remains unchanged.

• Connects up to twelve discrete signals via a single fieldbus address and integrates them into the control technology.
• Intrinsically safe ignition protection for sensors in Zone 0.
• Monitoring of wire breaks, short circuits, valve breakaway, and runtimes facilitates needs-based, targeted maintenance.
• Automatic partial stroke test extends maintenance interval.
