The WM20 completes, in its medium-low end, the range today covered by the WM30 and WM40.

It bears a totally new LCD display, which clearly shows the contrasted variables and the relevant indications.

The WM20 is user-friendly analyser which can be equipped with:

• 1 output module (either relay or static versions)
• 1 communication module (among Modbus, both versions, BACnet, both versions, and Profibus)

The above modules make the WM20 the ideal solution for several applications mainly targeted at the building and industrial automation markets.

The optical port at the front can be used via the OptoProg interface in order to:

• connect the analyser with PC/tablet for configuration or real-time diagnostic/datalogging via UCS Universal Configuration Software
• upload/download configuration files without any external device, just connecting the OptoProg interface and pressing a button
• datalog plant history (up to 20 days) directly on board of the OptoProg interface, for a deferred analysis

The WM20 “new design” will become the common family feeling of the whole WM range of products.
