FB1208B Digital Input

• 8-channel
• Inputs Ex ia
• Installation in suitable enclosures in Zone 1
• Module can be exchanged under voltage (hot swap)
• Dry contact or NAMUR inputs
• Positive or negative logic selectable
• Simulation mode for service operations (forcing)
• Line fault detection (LFD)
• Permanently self-monitoring
• On/Off delay

Function

The device accepts digital input signals of NAMUR sensors or mechanical contacts from the hazardous area.
Open or short circuit line fault alarms are detected.
The inputs are galvanically isolated from the bus and the power supply (EN 60079-11).
