Connecting sensors to DiPro 1500
Sensors can be plugged into the numbered banana jacks at the left side of the box. A
ground jack is also available if you cannot get a good ground for a sensor at the press.

SENSOR INPUTS
Figure 1-2. DiPro 1500 inputs on left side of box
Low impedance inputs
Inputs 1, 2, and 3 are low impedance inputs. They recognize a sensor's closure to
ground when the resistance in the circuit drops below 700 ohms. These inputs are
good for use with electro-mechanical sensors located in a wet area. Water (or
water-based lube) on the sensor could act as a conductor, causing current to flow in
the circuit even with the contacts open. False signals would occur. The low
impedance input blocks these false signals. It ensures that only signals from a firm
sensor contact closure are received by the controller.
High impedance inputs
Inputs 4, 5, and 6 are high impedance inputs. They recognize a sensor's closure to
ground when the resistance in the circuit drops below 7000 ohms. These inputs are
good for situations where an oil coating prevents a firm sensor contact closure or
prevents a good ground. Oil can act as an insulator and create resistance in the
sensor circuit even with the sensor contacts closed. But as long as the resistance is
not more than 7000 ohms, these inputs will detect the contact closure.
Using the inputs
You can plug any sensor into any jack whether it is a high impedance or low impe-
dance input. In most cases, which inputs you use will not matter. However, if you
have the problems described above, use the different inputs to correct the problem.
These inputs work the same way even if you use the DiPro Remote Connection Box
or Wintriss Sensor Interface for sensor connections instead of the side jacks.
NOTE:
Electronic sensors will not be affected by liquids as described above. Use
them with any input, even in wet or oily areas.
