Wired Input
From VersaVision Support
OVERVIEW
Inputs on an I/O Module or MIM can be used to connect to a machine through a wired connedtion.
Two types of input circuits can be used in these modules, dry contact or DC signal. Each of the (4) contacts can be configured separately. The configuration is decided by the state of the associated switch (S1) and which of the 3 terminals the wiring is connected to.
This page explains where the inputs are on the I/O and how to wire it according to the type of signal being used.

CONTACT TYPES
- Dry Contact - Non-Voltage
- The dry contact configuration looks for a contact closure/open between DI#+ and V+.
- There should be no voltage, from the Machine, connected to this input.
- Power for the connection will be provided by the VersaCall I/O Module.
- DC Signal Contact - Voltage
- The DC signal configuration looks for a DC voltage input.
- This input is looking for a change in the voltage state from a high state of anything over 1.5 – 26 VDC to a low state of 0 - 0.9 VDC.
CONTACT INFORMATION
- Downtime
- Use this contact to signal when the equipment is in a down state (not producing). The user decides what constitutes downtime.
- Depending on the equipment, the signal can come from different sources. PLC or Control Circuitry is the easiest method to pull a contact from.
- The contact can come from a non-Auto Run state. It is possible to connect multiple relays in parallel to achieve the desired result.
- Equipment can be considered down when there is a power loss.
- Equipment can be considered down when the E-stop has been activated.
- Equipment can be considered down when there is no power to a certain motor.
- Count
- Use this contact to signal when a part has been completed. Depending on the type of equipment, the contact can come from a variety of different sources.
- A sensor such as an electronic eye can indicate a count when the plane is broken.
- A signal such as a machine cycle can indicate when a count is completed.
- An external button press from an operator can indicate when a count is completed.
- Use this contact to signal when a part has been completed. Depending on the type of equipment, the contact can come from a variety of different sources.
- Equipment Fault
- Use this contact to determine when equipment generates a fault.
- This contact would come from a PLC or other control circuitry equipment where faults have been programmed into the equipment's logic.
- Use this contact to determine when equipment generates a fault.
- Sensor Limit
- Use this contact to determine when a sensor reaches a critical limit.
- This requires a special type of sensor to trip a contact at a certain point.
- Common examples are the monitoring of temperature, pressure or some fluid level.
- Use this contact to determine when a sensor reaches a critical limit.
