DEFINITIONS:
Hazardous voltages have been defined as the ranges: 75...1500 Volt DC, and
50...1000 Volt AC.
Technicians are qualified persons educated or trained to mount, operate, and
also troubleshoot technically correct and in accordance with safety regulations.
Operators, being familiar with the contents of this manual, adjust and operate
the knobs or potentiometers during normal operation.
RECEIPT AND UNPACKING:
Unpack the module without damaging it and make sure that the manual always
follows the module and is always available. The packing should always follow
the module until this has been permanently mounted.
Check at the receipt of the module whether the type corresponds to the one
ordered.
ENVIRONMENT:
Avoid direct sunlight, dust, high temperatures, mechanical vibrations and shock,
as well as rain and heavy moisture. If necessary, heating in excess of the stated
limits for ambient temperatures should be avoided by way of ventilation.
All modules fall under Installation Category II, Pollution Degree 1, and Insulation
Class II.
WARNING
This module is designed for connection to hazardous electric
voltages. Ignoring this warning can result in severe personal
injury or mechanical damage.
To avoid the risk of electric shock and fire, the safety instructions
of this manual must be observed and the guidelines followed.
The specifications must not be exceeded, and the module must
only be applied as described in the following.
Prior to the commissioning of the module, this manual must be
examined carefully.
Only qualified personnel (technicians) should install this module.
If the equipment is used in a manner not specified by the
manufacturer, the protection provided by the equipment may be
impaired.
WARNING
Until the module is fixed, do not connect hazardous voltages to
the module. The following operations should only be carried out
on a disconnected module and under ESD-safe conditions:
Dismantlement of the module for setting of dipswitches and
jumpers.
General mounting, connection and disconnection of wires.
Troubleshooting the module.
Repair of the module and replacement of circuit breakers
must be done by PR electronics A/S only.
GENERAL
HAZARD-

WARNING
5202B4:
To keep the safety distances, one relay must not be connected
to hazardous voltage at the same time as the other relay on the
same channel is connected to non-hazardous voltage.

Manufacturer’s signature
MOUNTING:
Only technicians who are familiar with the technical terms, warnings, and
in struc tions in the manual and who are able to follow these should connect the
module.
Should there be any doubt as to the correct handling of the module, please
contact your local distributor or, alternatively,
PR electronics A/S, Lerbakken 10, 8410 Rønde, Danmark tlf: [phone].
Mounting and connection of the module should comply with national legislation
for mounting of electric materials, i.e. wire cross section, protective fuse, and
location. Descriptions of input / output and supply connections are shown in
the block diagram and on the side label.
The following apply to fixed hazardous voltages-connected modules:
The max. size of the protective fuse is 10 A and, together with a
power switch, it should be easily accessible and close to the module.
The power switch should be marked with a label indicating that it will
switch off the voltage to the module.
Year of manufacture can be taken from the first two digits in the serial number.
CALIBRATION AND ADjUSTMENT:
During calibration and adjustment, the measuring and connection of external
voltages must be carried out according to the specifications of this manual. The
technician must use tools and instruments that are safe to use.
NORMAL OPERATION:
Operators are only allowed to adjust and operate modules that are safely fixed
in panels, etc., thus avoiding the danger of personal injury and damage. This
means there is no electrical shock hazard, and the module is easily accessible.
CLEANING:
When disconnected, the module may be cleaned with a cloth moistened with
distilled water.
LIABILITY:
To the extent the instructions in this manual are not strictly observed, the
customer cannot advance a demand against PR electronics A/S that would
otherwise exist according to the concluded sales agreement.

• 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.

Function description:
Examples of connections on block diagram (1)...(4)
(1) NAMUR sensor with cable error detection in case of cable disconnection or
short-circuit.
(2) Mechanical contact with cable error detection in case of cable disconnection
or short-circuit, when Rs and Rp are mounted on the contact.
(3) Mechanical contact with cable error detection in case of cable disconnection,
when Rp is mounted on the contact.
(4) Mechanical contact without cable error detection.
jumper programming:
• When a channel 1 signal or cable errors are transmitted to channel 2, JP 22
must be in position 2-3, and JP 23 must be in position 1-2.
• Signal transmission to channel 2: If the channel 1 signal is inverted (JP11 in
position 2-3), the channel 2 signal will also be inverted. In this case, the
inversion on channel 2 can be reversed by inverting the channel 2 signal
(JP21 in position 2-3).
• When channel 2 is used individually, input 2 is activated by JP 23 in position
2-3.
