Connect Wiring to the Contact Input Option Card
The contact input card provides four connectors for termination of up to 24 individual dry contact
inputs. A screw terminal is provided for each input and accepts 4–0.5 mm
labeled to assist in referencing during termination.
Note:
1. Pull wire from the device supplying the contact closure into the DIN rail box that houses the
option card.
2. Strip the insulation from each wire pair back 6 mm.
3. Notice each connector is labeled for your wire termination reference. Using a 3 mm flatblade
screwdriver, loosen the terminals and insert each of the data + and data - wire set into the
appropriate terminal for the circuit.
• Data wires in the set are polarity independent.
4. Tighten each screw terminal until the wire is secure.
5. Repeat steps 1–4 for the remaining dry contact closures.
6. Noting the connector orientation, plug one end of the supplied wire harness into the five pin
connector on the upper right corner of the option card.
7. Noting the connector orientation, plug the other end of the wire harness into the "Option 1"
or "Option 2" connector labeled on the lower edge of the EchoDINcontroller.
