Usage Tips: Using A/C Inputs
to Sense Dry Contact ClosuresMost Notifact devices come standard with four dry contact
inputs and four AC voltage-sensing inputs, but did you know the AC inputs can be converted for use as dry
contacts? Here's how:
When using any of the four AC inputs to monitor dry contact points, such as a
temperature monitor, just energize the circuits to 24 Vac. You can use a 110 Vac to 24 Vac transformers
to step down the voltage if needed. Only the AC inputs that are used need to be energized.
