Option 4 NPN KOSMOS OPTOS

Option of 4 programmable SETPOINTS across the entire display range. Can be added to the instrument providing alarm and control capabilities via individual LED indicators and NPN transistor outputs.
All setpoints have programmable delay by timing (in seconds) or symmetric or asymmetric hysteresis (in points) and selectable HI/LO activation mode.
Furthermore, it is possible to configure the alarms to operate independently (each one triggering at a different setpoint) or to condition the activation of one or two of them on the activation of the main alarms. This latter function is referred to in this manual as TRACK, and its numerous applications are described on the following pages.
In the 4 setpoint option, one of them also features automatic drag. The options are supplied as plug-in cards that activate their own programming software, fully configurable by the user, and whose access can be independently blocked by a switch connected to the base of the instrument.
