What are the iO1000 auxiliary power output ratings for powering external 24VDC devices?

The iO1000 provides two auxiliary power outputs, Aux 1 and Aux 2, each rated at 500 mA at 24 VDC nominal (Page 4) [1].

Aux 1 is a continuous circuit typically used for two-wire smoke detectors or remote annunciators, while Aux 2 is a resettable circuit that can be software-configured for continuous operation (Page 31) [1].

Key specifications include:

1. Total Capacity: Aux 1 and Aux 2 can supply a combined total of 1.5 A (Page 31) [1].

2. NAC Power Trade-off: Any current draw exceeding 0.5 A total across both outputs reduces the available Notification Appliance Circuit (NAC) power by that same amount (Page 4) [1].

3. Voltage Range: 21.9 to 28.3 VDC (Page 4) [1].

4. Supervision: Both circuits are supervised for shorts and grounds (Page 4) [1].

5. Ground Fault Impedance: 0 to 5 kΩ (Page 31) [1].
