More Info
The following is specifications and dimensional information on the housing for the Moduloc Control Systems Model MD85100  of Self Contained “All-in-One” Digital Hot Metal Detector.

 

Additional Technical Information

To accommodate variation in bar temperature and background IR, various precise threshold are programmable via covered switches from 250°C to 1,000°C ( 518°F to 1832°F) to ensure reliable switching with reference to both the displayed background and product IR signal. Furthermore, response time is programmable from 1ms to 250ms to accommodate black spots on the bar.

The MD85100 incorporates a remote self-check facility remotely energized by closed contacts that lights up an internal IR LED to switch the detector and verify its' outputs operate correctly.

The MD85100 will operate from either 80-240 VAC or 24VDC power input. Standard outputs include a cradle relay, a fast reed relay and both NPN/PNP transistor outputs.
