Pilz PNOZ m EF 4AI analog input module

The latest Pilz analog input module PNOZ m EF 4AI expands the PNOZmulti 2 range of configurable, safe small control systems. It can be used to safely record and monitor any process up to PL e or SIL CL 3. One particular advantage is the separate module program (mIQ) which can be used to make fine-granular adjustments of the measured value.

The separate module program mIQ provides fast reaction times with its decentralised processing in the module. PNOZ m EF 4AI uses the PNOZmulti Configurator software tool to provide software blocks for input, plausibility, scaling and arithmetic functions. Even while configuring, the analog measurement values can be scaled in numerical quantities with any unit. The limit value, range or working area monitoring can easily be parameterised via the software module with a few mouse-clicks. The concept guarantees that the standard measurement range of sensors is safely maintained.

The module provides four independent, safe analog 4–20 mA current inputs with a resolution of 15 bits plus sign bit. The measurement range is 0–25 mA.

Arithmetic functions such as averaging, differential pressure calculation etc facilitate the use and enable more exact and faster diagnostics. Up to six analog values per module can be transferred to the fieldbus, so that processes can be accessed faster. In combination with the PASvisu visualisation software, analog values can be displayed and evaluated.
