Phoenix Contact Isolation Amplifier

Ex i NAMUR isolating amplifier For operating proximity sensors and switches in Ex areas. The signals are transmitted via 2 relay outputs (N/O contact) to the safe area. Line fault detection (LFD), 3-way isolation, SIL 2.

Your advantages: 

• Power supply and error indication possible via DIN rail connector  
• Installation in zone 2, protection type "n" (EN 60079-15) permitted  
• Up to SIL 2 according to EN 61508  
• Line fault detection (LFD), can be activated/deactivated, error indicated by red flashing LED with de-excitation of output relay  
• 4-way electrical isolation  
• Direction of operation can be selected (operating or closed circuit current behavior)  
• 2 relay signal outputs (N/O contact); output 2 can also be used as an error signaling output  
• Input for NAMUR proximity sensors (EN 60947-5-6), floating contacts or contacts with resistance circuit, [Ex ia] IIC  
• LED indicators for supply voltage, switching state, and malfunction according to NAMUR NE 44
