NAMUR isolation amplifier for operating proximity sensors and switches. The signals are transmitted to the

control level via 2 transistor outputs (passive). Line fault detection (LFD), 3-way electrical isolation, SIL 2.

The illustration shows the versions

■

Up to SIL 2 according to EN 61508

■

Line fault detection (LFD), can be activated/deactivated, error indicated by red flashing LED with disabling of transistor output

■

Signal output 2 can also be used as an error signaling output

■

LED indicators for supply voltage, switching state, and malfunction according to NAMUR NE 44

■

2 transistor signal outputs (passive); up to 5 kHz
