MSA 9010/9020 LCD and 9020-4 LCD

The control system 9010/9020 LCD provides maximum flexibility, simple operation, high reliability and superb performance at considerably reduced costs. In combination with the large range of MSA gas sensors, the 9010/9020 LCD excels in a variety of industrial applications there could be a presence of dangerous gas concentrations.
The 9010 LCD control module processes signals from one gas sensor while the 9020 LCD processes signals from two independent gas sensors. The system is also available as a single or dual channel wall mount and in ABS housings or as 19” rack version with up to 5 or 10 modules.
The 9020-4 LCD is identical to the 9020 but is configured as a four-channel IP65 controller to suit marine and industrial applications.

For more information, please see leaflets 07-516.2 and 07-517.2.
