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 MultiCONTensures the powering of the 2-wire transmitters likewise capable of realizing complex control tasks. The MultiCONT unit 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 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. The internal current outputs (max. 2 pcs.) of the MultiCONT can 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 MultiCONT can handle, further MultiCONT units 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.
