Chapter 2 │General Introduction
Purpose of the MX 43 controller
This controller is intended for the continuous measurement and control of the
gases present in the atmosphere.
Wall-mounted MX 43
Rack-mounted MX 43
8-relay modules and 4 4-20
mA output modules
Figure 1: Wall-mounted MX 43 and examples of the modules.
The system primarily comprises:
■a wall-mounted MX 43 (4 or 8 lines) or rack-mounted MX 43 (8 lines);
■different modules (detector with digital or analog output, logic inputs,
analog inputs, relay outputs, and analog outputs).
The MX 43 instantly handles the measurements of detectors and input
modules. As soon as the measurements reach the programmed limit, a sound
and visual alarm are given. At the same time, the corresponding relay or
relays are activated, in turn controlling the additional internal or external
actions envisaged by the user.
The MX 43 controller is programmed by using the COM 43 application.
Figure 2 presents a configuration example.
