Wintriss DiPro Sensor Interface (DSI 2)

The DiPro Sensor Interface (DSI 2) allows you to connect most electromechanical and discrete-output electronic sensors to your die protection control.
Some die mounted junction boxes are not compatible with the DSI 2. See our Application Note

The DSI 2 is available with 8 sensor inputs, and features a built-in 24VDC power supply to power your sensors.

The DSI 2 has built-in pulse stretching on inputs 1-4 (also on inputs 9-12 on 16-input units) to stretch very fast signals (usually from part ejection sensors) out to a duration of 10mSec.

The DSI 2 is a flexible sensor connection solution.   It is available with or without front- panel connectors for wiring individual sensors, along with a variety of larger connectors
(including a heavy duty 19-pin M23 connector) for use with die-mounted junction boxes that allow you to connect up to eight sensors to the DSI with a single cable.

Wintriss offers a complete line of sensors and connectivity products including proximity and photoelectric sensors, die-mountable junction boxes, cables, and connectors.

The DSI 2 is compatible with all versions of SmartPAC 2, SmartPAC 1, and DiPro 1500.

Application note Die-Mounted Junction Boxes

• Some 3rd Party Die-Mounted Junction boxes are NOT compatible with the DSI-2
• One of the most innovative features of the DSI 2 is its ability to accept input from either NPN or PNP sensors without having to do any special wiring, programing, or configuration; you just plug in either type, and the DSI-2 can monitor it.
• Because of this feature, the DSI 2 is incompatible with any die-mounted junction box equipped with LED indicators, such as the one shown below.

• In order for the DSI 2 to have the ability to monitor either NPN or PNP sensors, its inputs look for current flow rather than a specific voltage level. As long as a sensor is actuated, the DSI will detect that it is "On" whether the input voltage level is 0 volts or 24 volts.
• If the die-mounted junction box is equipped with LED indicators, these components can cause current to flow through the DSI input even when the corresponding sensor is not actuated, leading to a condition where the inputs appear "locked" on. 
• The easiest way to avoid this condition is to utilize only "plain" junction boxes without indicator lights.
