APC Dry Contact I/O Accessory for UPS Management

The APC AP9810 is an accessory with two dry contact inputs and one relay output that expands how you monitor and control an APC uninterruptible power supply. It connects to the Universal I/O port on compatible UPS Network Management Cards, allowing you to feed external alarms or sensor data into the same interface that already tracks power events.

Installation is simple because the unit ships with a Cat 5 Ethernet cable. Once in place, the inputs can receive signals from devices such as door switches, leak detectors, or environmental sensors, while the relay output can forward UPS status changes to another system or activate a local indicator. All configuration happens through the familiar APC web interface, so no additional software is required.

Data center technicians, facilities teams, and managed service providers use the AP9810 when they need UPS information to interact with broader site monitoring. In a small server room, it can send an on-battery event to a building alarm panel. In remote edge locations, it offers a cost-effective way to watch for unauthorized access and receive instant notifications through the same network card that already reports power conditions. The compact housing fits easily on a shelf or inside an enclosure, so it never competes for rack space.

The accessory operates reliably in temperatures from 32 to 104 degrees Fahrenheit and in humidity up to 95 percent. It meets EN 61000-4 electromagnetic compatibility standards and contains no moving parts, which helps ensure long service life. A two year warranty from APC provides additional peace of mind.
