GasScreen 40 Multi-channel control unit ■ 4 channels 4-20 mA ■ Large 5” colour touch screen display ■ Maximum versatility ■ Easy assembly and configuration ■ Powerful CPU for input and alarm management ■ Optional WiFi and Datalogging The control unit for gas monitoring GasScreen 40 enables the connection of 4 inputs in 4-20mA or 16 inputs in RS-485. The input terminal block also accepts 0-20 mA signals, or in Volts (0-5 V, 0-10 V), making this control unit versatile also for managing sensors with different input logics. The connectable sensors can be all those available, for combustible gases, oxygen and toxic gases. The configuration of the connected sensors, as well as the detection parameters and alarm modification, are carried out on a large and comfortable 5" colour touch screen display, in a simple and intuitive way, which displays the measurement in real time, the relative unit and the type of gas detected, providing clear information in case of alarm: The channel display in alarm will turn yellow in case of fault alarm (sensor malfunction or absence of electrical signal), orange if the first alarm threshold is exceeded and red if the second alarm threshold is exceeded. During the configuration steps, the user is guided by a simple and functional menu. For slight deviations around the sensor calibration value, it is possible to act directly on the GasScreen 40 from the relative auto-calibration menu, thus being able to align the measured value without having to act on the sensor. A bottom plate for wall mounting ensures easy installation on any type of surface. The CPU is set up for local wireless or GPRS connection (by inserting an optional card inside the instrument); Internet connection is available on the Ethernet socket. The datalogger (optional) enables the storing of up to 30 days of measures at one-minute intervals, as well as all alarm events that occurred during the given period, and these data can then be exported to a USB stick to visualise trends in the gas concentration graph, directly on the large display.

For each channel there are 2 relay contacts (8 relays in total); then there is a general alarm contact, a fault alarm relay common to the 4 channels and 2 "spare" relays that can be used, for example, in case of TLV alarms.

The colour display indicates the alarm level (yellow stands for fault, orange for first threshold exceeding and red for second threshold exceeding, while green indicates no alarm in progress). 4 channels are displayed simultaneously, each with its own identifying name, gas name and corresponding mA output. If there are more than 4 sensors connected, the channel that goes into alarm is automatically displayed on the main screen. In the programming menu, you can enable/disable each channel. Then, for each active channel, it is possible to select the gas name from a drop-down menu (from a...
