PR 3202 Pulse Isolator / Switch Amplifier
PR 3202 Pulse Isolator / Switch Amplifier
The PR 3202 pulse isolator and switch amplifier from PR Electronics offers high 4-port isolation to provide surge suppression and protect the control system from transients and noise while eliminating ground loops.
- 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 16.8-31.2 VDC
Description
- 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 mount in Safe area or in Zone 2 / Division 2 areas
- all terminals offer over-voltage protection, polarity protection, and short-circuit protection
PR 3202 Pulse Isolator / Switch Amplifier
- 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 -13 to 158˚F (-25 to 70˚C)
- NAMUR NE21, NE44
- conforms to IEC 60947 standard – switch amplifiers for NAMUR sensors
Easy Programming and Mounting
- easy configuration via DIP-switches
- applicable devices can configure via DIP-switches
- the DIP-switches are on the side of the device and can adjust with a small screwdriver or other implement
- remember to cycle power for power rail / terminals to reload DIP-switch values at power up
- the PR 3202 features two independent outputs: Out 1 and Out 2
- the two outputs are normally open / not energized
- Out 2 can be a copy of input to form a splitter functionality or Out 2 can indicate LFD alarm
- each output can invert individually
- units can mount side by side, horizontally, and vertically, without air gap on a standard DIN rail, even at 158˚F (70°C) ambient temperature
- units can receive supply separately or install on PR 9400 power rail
- the narrow 6.1 mm housing allows up to 163 units per meter
User-Friendly Operation and Troubleshooting on the PR 3202 Pulse Isolator / Switch Amplifier
The PR 3202 pulse isolator and switch amplifier provides multiple features for easy user operation and for performing efficient troubleshooting. Monitoring the operational status is easy from the front LED(s).
