1. APPLICATION
The UNICONT PJK-1-4 is a universal interface module that
can be controlled via HART or MODBUS protocol through an RS485
interface, and (depending on type) provides relay(s) and/or 4…20 mA
current output(s).
The device is intelligent, the internal functions and services can be
set with the help of a communication protocol: the transmitter outputs
can be scaled. The error detection function can be switched on and
off. The state, in which a given output unit should be when an error
occurs, can also be set. The device can be used with Nivelco’s
MultiCONT PR-1-units as an output extension module,
and also as a peripheral device for PLC or PC controlled process
control systems. N: number of outputs of a given type of output units

4.2 RS485 COMMUNICATION TERMINALS
TB – terminator contact,
interconnect with point
„B”
B– negative terminal of
RS485 data connection
A– positive terminal of
RS485 data connection
SHLD – shielding
The Universal Interface Modules should be
connected one after another to one cable
pair. Star topology is not allowed. Max. cable
length is 1000 m, but in this case a shielded
twisted cable pair (STP – Shielded Twisted
Pair) should be used. Max. cable capacity
should be less than 100 pF/m.
All of the Universal Interface Modules in one
system should have different addresses
(0…31), see: 5.1.2.

5. INSTALLATION, SETTING UP AND PROGRAMMING
5.1. PREPARATION
5.1.1 CHOOSING A COMMUNICATION PROTOCOL
Open the housing via the four snap-on clips to
access the DIP switch for protocol selection.
DEFAULT SETTING: HART
5.1.2 SETTING THE DEVICE ADDRESS
A communication line can contain max. 32
Universal Interface Modules. These modules
should have different addresses.
Set the address with the „ADDRESS” DIP
switches (0…31), on the front panel of the device.
Settings will take effect when the unit is switched
on again!

5.3.2 OPERATION
-After the self test sequence, if the device is ready for operation, states and operation of the module and
its units are shown as follows:
-‘COM’ LED – indicates the communication with the unit that belongs to it, (all LED-s flash in case of
communication with the module), it also indicates the operation state of the device.
-‘STATUS’ LED – indicates the state of the unit that belongs to it.

5.3.3. PROGRAMMING, SETTING THE CURRENT GENERATOR AND RELAY OPERATION
Depending on the application, re-programming of the device may be needed. Programming can be done
with either a PC that controls the communication network via HART or MODBUS protocol, or a
MultiCONT (see MultiCONT’s User Manual). Parameters determining the operation:
