Pulse isolator / switch amplifier
3202
- Input: NAMUR, NPN open collector, contact
- Output: 2 x relay or NPN transistor output
- 2.5 kVAC 4-port galvanic isolation
- Line Fault Detection (LFD) / cable break detection
- Power supply 16.8 VDC…31.2 VDC
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.
