The Nivelco MultiCONT multi-channel process controller 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 likewise capable of realizing complex control tasks. The MultiCONT multi-channel process controller supports communication with a maximum of 15 standard or 4 Ex ia 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 ia version transmitters. Remote programming of the transmitters and downloading of the parameters and measured data is possible using this multi-channel process controller. 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. The internal current outputs (max. 2 pcs.) of the Nivelco MultiCONTcan transfer and even modify information supplied by the transmitters. The built-in relays (max. 5 pcs.) can be freely programmed and assigned to the transmitters. If a system contains more transmitters than one MultiCONTcan handle, further MultiCONTunits can be organised in chain via RS485 interface. The large dot-matrix display allows visualisation of a wide range of informative display functions. One special feature is the "Echo-Map" visualisation when communicating with NIVELCO's EchoTREK and EasyTREK transmitters.

Trend Logging (Optional);
Onboard logging capable versions of MultiCONTare able to store measurement values and three additional parameters of the connected transmitters in a measurement system into the internal FLASH memory or an SD memory card. The two modes, time-controlled and event-controlled logging modes can be used simultaneously. Monitoring the average, minimum and maximum value or highest values of the flow can be used only for NIVELCO manufactured transmitters used in flow-metering mode. Content of the internal memory is retrievable through USB port, within the capacity of 65000 entries. Maximal capacity of the applicable SD card is 2 GB.
Nivision Process Visualisation Software (Optional);
RS 485 capable versions of MultiCONT are able to communicate with NIVELCO’s NIVISION process visualization software to indicate parameters of a process control system graphically on a process controller PC. The process, the measured values or any further processed values can be visualized also in tabular form with NIVISION. The NIVISION performs data logging, trend monitoring, database handling and various other tasks in addition to a basic visualization. The software is sold as a custom-tailored product.
