Isolador de Pulso
Principais características

2 channels - 2 or 4 outputs
Dual output
5-port 3.75 kVAC galvanic isolation
Cable error detection
Universal supply by AC or DC


Pulse isolator for the supply of NAMUR sensors.
Pulse isolator for the detection of mechanical contacts.
One input signal can be used on two separate outputs.
A cable error alarm can be detected on a separate output.

Mounted vertically or horizontally on a DIN rail. Up to 84 channels per meter can be mounted.


PR5202A1 and 5202A2 have relays with change-over contacts or open NPN collectors.

PR5202A4 has 4 SPST relays, which are activated simultaneously two and two. Each relay can be programmed to the function N.O. or N.C.

Inputs, outputs and supply are floating and galvanically separated.

5202 is designed according to strict safety requirements and is therefore suitable for application in SIL 2 installations.
