PI31 Programmable indicator vertical


Digital indicator with 2 programmable alarm contacts for display, monitoring and regulation of temperature and process values. Panel installation, available in many standard or customer-specific measurement ranges.


In addition to the display of measurement values the Pi-indicator has two programmable switch contacts through which various switch functions can be realised. By using a single-chip micro-controller all settings, switch points and switch functions can be simply programmed by the user. The Pi-31 indicator is supplied including mounting and connection components in a vertical DIN housing for panel installation 48×96 mm. Thanks to the internal universal input card a large number of input ranges are possible. This can also be supplied completely installed in a cabinet, possibly with connection clamps and wiring.
