Thank you for choosing a NIVELCO instrument.
We are sure that you will be satisfied throughout its use!
1. INTRODUCTION
The MultiCONT unit is a universal interface between NIVELCO’s HART-capable intelligent level transmitters and the other elements of the process control system
like the PC-s , PLC-s, displays and the actuators. Besides its role as an interface, the MultiCONT ensures the powering of the 2-wire transmitters while being capable
of complex control tasks. The MultiCONT unit supports communication with a maximum of 15 standard or 4 Ex certified NIVELCO’s HART-capable 2- and / or 4-wire
transmitters. If MultiCONT is used with NIVELCO’s MicroTREK microwave level transmitters the maximum number of transmitters in a loop should not exceed 8 pcs.
for normal transmitters and 2 pcs. for Ex version transmitters. If a system contain more transmitters than one MultiCONT can handle, further MultiCONT units can be
wired in series via an RS485 line. Remote programming of the transmitters and downloading of the parameters and measured data is possible using the MultiCONT.
The various outputs such as 4 … 20 mA, relays and digital outputs can be controlled using measured values and new values calculated from the measured values.
Measured values (Primary Value and three additional values) are able to be logged.
Large DOT matrix LCD panel facilitate a wide variety of display functions including tank content visualisation. The type and number of outputs of the basic unit can be
expanded with external (relay and/or current output) PJK-100 type Universal Interface Modules. The total number of relays included in the MultiCONT and in the
modules must not be more than 64, while that of the analog outputs (4…20 mA outputs) can be maximum 16. A further restriction is that there can be a maximum of
32 Universal Interface Modules.
Explosion proof certified versions of the MultiCONT should be installed outside the hazardous area.
