As part of its LB system remote I/O solution, Pepperl+Fuchs offers a power supply for use in Zone 2, Class I/Div. 2 explosion-hazardous areas.
This 24V remote I/O power supply in protection type Ex nA feeds the I/O modules and com units/gateways mounted on the corresponding backplane.
Based on the number of I/O modules and power consumption, a third remote I/O power supply in standby operation is needed for redundancy mode.
Features:
- 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.
