Pulse isolator / switch amplifier 3202

Functional highlights

• Interfaces a NAMUR sensor to typical control system input cards.
• High 4-port isolation provides surge suppression that protects the control system from transients and noise and eliminates ground loops.
• Provides simple splitter function: 1 in – 2 out.
• Monitor signal source for cable short-circuit or cable break with alarm function on secondary output, power rail and LED status.
• The device can be mounted in Safe area or in Zone 2 / Division 2 areas.
• All terminals are over-voltage protected, polarity protected and short-circuit protected.

Technical highlights

• Output options: NPN transistor or mechanical relay.
• Response time: Relay < 20 ms / NPN < 0.1 ms.
• Collective DIN-rail alarm.
• Line Fault Detection (LFD) / cable break detection.
• Wide ambient temperature range -25...70°C.
• NAMUR NE21, NE44.
• Conforms to IEC 60947 standard - switch amplifiers for NAMUR sensors.

Programming

• Easy configuration via DIP-switches.

Mounting

• Units can be mounted side by side, horizontally and vertically, without air gap on a standard DIN rail, even at 70°C ambient temperature. 
• Units can be supplied separately or installed on PR 9400 power rail.
• The narrow 6.1 mm housing allows up to 163 units per meter.
