Issue
What are the pulse input ratings for a Niagara G3 Jace-6?
Environment
Niagara G3
Cause
Job site has pulse meters which require termination to the Jace-6.
Resolution
The universal inputs support both pulse contacts and normal dry (equipment status) contacts.
- Pulse contacts may have a change-of-state (COS) frequency of up to 20 Hz with a 50% duty cycle. Note: Minimum dwell time must be > 25ms.
(Contacts must remain open at least 25ms and be closed at least 25ms.) - Standard dry contacts must have a 1 Hz. (or less) COS frequency, with minimum dwell time > 500ms.
(Contacts must remain open at least 500ms and be closed at least 500ms.)
Both types of dry contacts support 3.3 Vdc open circuits or 330 μA short-circuit current.
