DP2200 Analogue threshold display
6
3 Intended use
The device is used for the evaluation of an analogue signal (4...20 mA) from a connected sensor or
another device with analogue output (4...20 mA). The device has one analogue current input and two
outputs: output 1 (digital) and optionally output 2 (analogue current output).
The unit is not suited for environments with particular requirements on mechanical stability (e.g.
shock/vibration).
The unit is intended for indoor use only.
u Observe the operating conditions (Ò Technical data at www.ifm.com).

The current loop of the analogue input must be terminated. Only one load may be connected,
either an internal or an external load.
