The Dry Contact I/O Accessory includes: Inputs (labeled Zones A and B) for two dry contact devices One 12 V, 25 mA power output (labeled Pwr) One Form C relay (relay outputs labeled Output). Dry Contact I/O Accessories connect to Universal I/O ports on your Management Card 2: AP9635 includes one port and AP9631 includes two ports. Through your Management Card 2 software interface, you specify which alarms will cause a change in the state of the Form C relay. You also set the actions that will occur at the host due to a change in state of your dry contact devices. Installation Install the Dry Contact I/O Accessory using the details below. Connect devices to the screw terminal block using the following subsections. Item Description Screw terminal block accepts 16 AWG to 28 AWG wires Dry Contact I/O Accessory 25.4 cm (1 ft) CAT-5E RJ-45 patch cable used to connect the Dry Contact I/O Accessory to a Universal I/O port on a Management Card 2 Note: The Management Card 2 must have application firmware v5.0.2 or greater. For details on upgrading the Management Card 2 firmware, see the users guide on the Network Management Card Utility CD or on the APC Web site (www.apc.com). Note: If you are using PowerChute Network Shutdown (PCNS) and if your Management Card 2 has two Universal I/O ports, you must connect the Dry Contact I/O Accessory to Universal I/O port 2. PCNS supports only one Dry Contact I/O Accessory. dmp0114aConnecting dry contact devices to the Zone A and B terminals on the screw terminal block The sensing voltage available on the Zone A and B pins of the Dry Contact I/O Accessory is nominally 5 Vdc at less than 1 mA, referenced to system ground. Connecting a device to the power output (Pwr) terminals on the screw terminal block You can use the NO/GND terminal on the screw terminal block to connect Normally Open (NO) dry contact devices and to connect a device to the power output (Pwr) terminals. 2 Dry Contact I/O Accessory (AP9810) Technical Guide
