Description
The model DI25 digital indicator is a multi-function, competitively priced instrument for a wide variety of measuring tasks.
The basic version of the DI25 indicator features three alarm outputs. Instruments with the optional DC 24 V transmitter power supply have two alarm outputs available.
With the high IP66 ingress protection at the front, the DI25 digital indicator is also suitable for use under harsh environmental conditions.
All configuration and programming can be carried out through the front-panel keys.
Features- Multi-function input for current and voltage signals and thermocouples and resistance thermometers.
- Ingress protection IP 66 (front panel).
- two or three freely programmable alarm outputs as standard (depending on the instrument version).
- 4 ... 20 mA Analog signal output as standard.
- HOLD function.
