PMX420 SERIES<br />
Universal, four-digit, current/voltage display<br />
Typical application of PMX 420 Plus<br />
The current/voltage displays of the PMX420 SERIES are<br />
available as a pure PMX420 display unit or optionally with<br />
analogue outputs/4 alarm outputs.<br />
The basic model is suitable for displaying all standard current<br />
or voltage signals. The inputs signals are electrically isolated,<br />
smoothed and scaled. An integrated power supply can be used<br />
for supplying external sensors and input devices.<br />

The PMX420Plus adds four alarm channels (each with it’s own<br />
status indicator and relay contact outputs) and a fully isolated<br />
analogue current/voltage output.<br />

Device functions can be configured, specifically for the<br />
application, using the integrated keypad on the front panel.<br />
There are also several other handy features like maximum and<br />
minimum value recall, integrated linearisation, an acoustic alarm,<br />
a group alarm function, and the option for manual or automatic<br />
alarm reset.<br />
