Moduli con segnale di uscita digitale

Pepperl+Fuchs provides digital output modules for control of intrinsically-safe solenoid valves, LED clusters, beacons, horns, or other standard switching functions. As part of the FB system remote I/O solution, these digital outputs feature terminals in protection type Ex i or Ex e for use in Zone 1 explosion-hazardous areas.

FB remote I/O digital outputs are available with different channel numbers to cover diverse application requirements:

• 1-channel versions with one digital output and two digital inputs are ideal for valve control. Through transmission of two binary input signals from NAMUR sensors or mechanical contacts, they ensure reliable valve position feedback from the field.
• 8-channel versions ensure the highest possible utilization of backplanes used for module connection, and enable compact remote I/O solutions with large channel numbers. Additionally, these modules feature shutdown inputs for bus-independent safety applications.

The digital output modules support lead breakage detection and short circuit detection. Galvanic isolation separates the inputs and outputs from bus and power. The modules are hot-swappable for quick and easy module replacement without time-consuming system shutdowns.
