Frequently Asked Questions (FAQ)

• What does "universal input" mean for the 1790D-T32BV0?
  It means each input point can be wired as either a sinking or a sourcing type without hardware changes.
• What voltage level is needed to turn an input ON?
  The input requires a signal between 9.6V DC and 28.8V DC to be recognized as ON.
• How are the input points grouped for common wiring?
  Inputs are grouped with 16 points sharing one common terminal (16 points/4 COM).
• Does this module provide electrical isolation?
  Yes, it provides 1250V AC RMS photocoupler isolation between the field inputs and the internal logic.
• Do you offer a return policy for this module?
  Yes, we support a 30-day return policy for qualified products.
