Discrete Output Lines
These individual signal lines are part of the 'Discrete Interface' cable and all are low power
outputs which use a common control line referenced (“ComO”; the green wire). This common
line is either a supply or ground return connection for these outputs.
a.
Low power means these outputs are intended for +9Vdc min to +24Vdc max @ 120 mA.
Refer to Electrical Interface Details in the Appendix for additional information.
b. All outputs default as normally open contacts, but can be configured as to normally
closed contacts. Note they still all use a common control line.
c. If the common control line is connected to ground, then all outputs are in low-side or
return path configuration. This means when VeriColor Spectro activates the 'pass' output,
it is providing a ground return for an external light or relay coil to turn on. See Figure 1.

d. If the common is connected to power (voltage ranging from +9Vdc to +24Vdc), then all
outputs are in high-side or supply path configuration. This means when VeriColor Spectro
activates the 'pass' output it is providing a positive voltage signal for an external light or
relay coil to turn on. See figure 2 on the next page.
