Rockwell Automation 1606-XL240-UPSE Power Supply Reference Manual - Manual (Page 11)

All parameters are specified at an input voltage of 24V, 10A output load, 25°C ambient and after a 5 minutes run-in time unless noted otherwise.
It is assumed that the input power source can deliver a sufficient output current.

14. Relay Contacts and Inhibit Input
The DC-UPS is equipped with relay contacts and signal inputs for remote monitoring and controlling of the unit.
Relay contacts:
Ready: Contact is closed when battery is charged more than 85%, no wiring failure is recognized, input
voltage is sufficient and inhibit signal is not active.
Buffering: Contact is closed when unit is buffering.
Replace Battery: Contact is closed when the unit is powered from the input and the battery quality test (SOH test)
reports a negative result.
Relay contact ratings max 60Vdc 0.3A, 30Vdc 1A, 30Vac 0.5A resistive load
min 1mA at 5Vdc min.
Isolation voltage max 500Vac, signal port to power port
Signal input:
Inhibit: The inhibit input disables buffering. In normal mode, a static signal is
required. In buffer mode, a pulse with a minimum length of 250ms is
required to stop buffering. The inhibit is stored and can be reset by
cycling the input voltage. See also section 27.3 for application hints. 7 +
