PULSE ISOLATOR
PRecon 5202B
• 2 channels - 2 or 4 outputs
• 5-port 3.75 kVAC galvanic isolation
• Dual output
• Cable error detection
• Universal AC or DC supply
Application:
• Pulse isolator with safety barrier for the supply of NAMUR sensors installed in
the hazardous area.
• Pulse isolator with safety barrier for the detec tion 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 sep arate output.
Technical characteristics:
• 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.
• The 5202B is designed according to strict safety requirements and is thus
suit able for application in SIL 2 installations.
Mounting / installation:
• Mounted vertically or horizontally on a DIN rail. Up to 84 channels per metre
can be mounted.
HOW TO DISMANTLE SYSTEM 5000
First, remember to demount the connectors with hazardous voltages.
Picture 1:
By lifting the bottom lock, the module
is detached from the DIN rail.
Picture 2:
Then, by lifting the upper lock
and pulling the front plate
simultaneously, the PCB is removed.
Switches and jumpers can now be
adjusted.
