Connecting Peripherals
Installation
Current Limiting Resistor
If a powered peripheral has inrush current over 10A, an in-line current limiting power resistor of 10Ω should be
used to ensure peripheral does not exceed max power draw, which may disrupt normal operation.
Max Line Resistance
The maximum line resistance for input wire runs should be less than 100Ω, exclusive of end-of-line
supervision resistors.
12V Power
12V Output terminals support up to 2A combined max.
Battery Backup
Battery should be sized to provide at least 4 hours of operation. The AX11 consumes 8.6W with no load (i.e.,
no inputs, outputs, or readers connected).
AC Field Wiring
If AC power is brought in via conduit, cut and splice wire going from AC inlet to PSU.
Inputs
AX11 has 16 Dry Contact Inputs. Nominal 5VDC. Line resistance should be less than 100Ω exclusive of EOL
resistor.
Relay Outputs
AX11 comes equipped with 16 Form C relays that can be driven dry. Max DC load: 24V @ 1A, Max DC current =
1A, Max DC voltage = 60VDC.
