Pulse Isolator
Key features

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

OVERVIEW

Pulse isolator with safety barrier for the supply of NAMUR sensors installed in the hazardous area.
Pulse isolator with safety barrier for the detection of mechanical contacts installed in the hazardous area.
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.

TECHNICAL DETAILS

PR5202B1 and 5202B2 have relays with change-over contacts or open NPN collectors available in the safe area.

PR5202B4 has 4 SPST relays, which are activated simultaneously two and two, available in the safe area. Each relay can be programmed to the function N.O. or N.C.

Inputs, outputs and supply are floating and galvanically separated.

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