Chapter 3—Installation and Wiring
Wiring Option #1—Four Isolated 24 Vdc Inputs
When using option #1, no connections are made to pins 6 or 7.
Wiring Option #2—Four Dry Contact Inputs
To use this option, pin 5 is shorted directly to pin 6. Pin 7 is
connected through a switch or relay to the appropriate input.
The maximum wire length from pin 7 to the corresponding
input is 10m.
DC Field Input wiring is accomplished with a 7-pin, 5.00 mm
pitch, removable screw terminal plug.
Note: When using Option #2, all wiring must meet PELV
requirements.
